Hurricane Season 2020 Forecast & Facts As We Know Them in Late April.
2020 Hurricane Names for the Atlantic Basin.
The names above are a FACT.
Not a FORECAST.
The first named storm will be Arthur.
Followed by Bertha.
The below is a FORECAST.
It's worth noting quality trumps quantity.
We can have more named storms but weak ones.
Conditions exist that inhibit them from strengthening.
When conditions exist that could enhance strengthening.
We have to pay attention and be ready to take action.
So don't look at last year's 18 named storms...
..and think oh CSU shows 2 less.
Last year we had many named storms ...
.... that were extremely weak!
Barely there ... but they got a name.
While some weak named storms always show up...
.. this year I'm worried on many stronger Hurricanes.
Major Hurricanes that could make landfall.
As always hope for the best ...
...but prepare for the worst.
The graphics are from TWC.
As always the NHC is the official source of information.
Please add it to your subscribed sites on YouTube.
As mentioned yesterday in my rant...
Many of us go to YouTube for news and updates.
I missed today's Cuomo Press Conference...
With 2 daughters living in New York I watch it usually.
... I'll check it out on YouTube after proofing this blog.
In 2020 we have many options.
From the Apps we use to the websites we use.
From the people we subscribe to ...
... to the links others share with us.
As I said yesterday "choose wisely"
Currently nothing is in the tropics to worry on...
We are in Severe Weather Season still.
A tornado warning exists today in Georgia.
That system moves into Florida and the Carolinas soon.
Off Africa there are your early pre-season waves.
And in the N Atlantic there are remnants of the last system.
Today's blog post is all about the Hurricane Season of 2020. I promised that yesterday and keeping my promise today. I'm giving my thoughts on our current situation with five important reasons that this coming Hurricane Season is forecast to be stronger than average and to have a higher potential for landfalling systems than other years when we could have a plethora of named storms that stay out at sea or fall apart victim to wind shear that is not forecast to be a large factor this year. That said, note wind shear forecasts are often iffy and subject to change but the patterns that exist and are evolving show a disturbing picture for what we will be facing sooner rather than later. The official start of the Hurricane Season in the Atlantic is June 1st, but very often we have an early season storm that makes landfall before the season officially begins. Mother Nature doesn't always obey the calendar rules as we all know when we see Springtime snow or Severe Weather in the Winter before Spring officially begins. Just as we can have 80 degree temperatures in North Carolina in March before a cold front races through and the temperature drops we may easily see Arthur in May not sometime in June.
When discussing "forecasts" for the Hurricane Season I need to mention Covid-19 because they will at some point collide and we must deal with it in an appropriate way. In the same way I'm giving an example of how forecasts and hyped headlines can change rapidly when dealing with Covid-19 from no worries on using a mask to cities and states advising you must wear a mask if you go to the store our outside in public. In the same way forecasts for a possibly weak season based on cool water temperatures may lead many to letting down their guard to suddenly having the rug pulled out from below them when a Major Hurricane such as Dorian is forecast to track dangerously close to their home towns in Florida. Forecasts are based on facts known at that time and they are subject to change so watch for updates frequently and learn from everything including our battle with Covid-19.
As promised yesterday I would buckle down today and begin a serious look at the 2020 Hurricane Season. It's been hard for me to jump into discussing this early as I normally do as we are all going through a difficult time dealing with the fast moving stream of information regarding Covid-19. Many of us have been personally impacted by the disease and the deaths of people we know and love as every day brings a new tragic story as well sometimes a happy story of someone leaving the hospital and going home that had previously been given low chances of surviving the disease. There seems to be a randomness to Covid-19 in that sometimes a young healthy person dies despite the discussion on older people being most at risk and then you read a story about some older person in their 90s who survived the disease. I believe all of the hype on how it mostly kills older people was over played and gave many younger people the misconception that they were almost invincible and that they only had to worry that their grandparents didn't die. While that is true on some levels, many young people have health conditions that go unnoticed or they simply were not able to fight off the disease. How often have you read about a high school football player who collapsed on a field in what seemed to be the healthiest phase of his life to only later find out he had a hidden heart defect that caused his death? The same such person would be a high risk if they contracted Covid-19 as often once in the hospital battling the disease the heart or the kidneys begin to collapse leading to a very long stay in the hospital or a devastating death for the family members who never expected he or she would succumb to the disease.
While mentioning the fact here that sometimes "facts" can be misconceived or misunderstood or sometimes later after learning more "facts" change - it's worth remembering that when looking at forecasts for the 2020 Hurricane Season. Sometimes, though rarely, weather conditions change unusually fast and a colder than average winter on the East Coast turns to a mild, winter without any accumulation of snow and despite the predictions made by experts "something changed" and that happened recently when the basketball season ended only to be followed by other sports stopping and theaters closing as we evolved into a world where the landscape looks different from any that we could have ever imagined. Oil dropped to a DOLLAR a BARREL and while gas is extremely cheap most of us are not currently commuting anywhere so supply and demand slammed an already difficult time for those who were used to being rich from the high price of oil. The Stock Market at all time record highs suddenly hit a wall and fell for days on end while many watched the value of their portfolios drop way lower than ever expected. While many said a correction was coming, no one saw the free fall that happened when the reality of the Corona Virus that was renamed Covid-19 became apparent and impacted the Stock Market.
Forecasts are predictions based on what we know currently as facts. Facts can often change.
Let's look back at the early Pandemic Predictions:
Cruise ship travel would most likely be okay.
No need to wear masks or gloves just stay a safe distance from others.
Social Distancing rules evolved from 4 feet to 6 feet to people feeling safer staying home.
Air Travel shouldn't be a problem was an early prediction and then.... we learned more facts.
Things changed.
The picture above is from the New York Times.
(Why isn't she wearing gloves?)
Hmnn ....
Note how spaced out passengers are here.
On Monday my best friend's two adult children who live in New York had to find a flight to Miami for the funeral for their father who died suddenly during the Covid-19 crisis in Miami to be with their other two siblings living there. The flights on JetBlue cost them $600 round trip each and there were only 50 passengers allowed on the plane with everyone spaced out wearing mandatory face masks and gloves. On Tuesday I watched with my best friend on Facebook Live that was live streamed the small funeral for friends and his many grandchildren to watch. Life in 2020 seems unreal but after a few weeks this has become "normal" and I mention it as I know many of us are going through similar sudden decisions on traveling to a funeral or wishing we could go to someone's house to comfort them and maybe bring a casserole but we are now limited to talking on Facebook Messenger, sharing pictures on Instagram and making a brief condolence call.
Below we have Alaska Airline crew members.
(Why don't they have on masks?
I know they are now wearing them.)
Maybe they thought the mask images would be scary.
A Seattle trip squeezed in fast to see my kids there.
Because I knew things would change fast.
Spoiler Alert: They changed even faster than I expected.
Faster than forecast... if you get my drift.
So while reading 2020 Forecasts for the Hurricane Season.
Remember they are forecasts.....
....they may change in real time.
They may verify... they may not.
Let's hope they do not because the forecasts are wicked.
Wicked in that all signs seem GO for a strong hurricane season.
Why you ask?
Showing five reasons below today.
I'll continue to list other reasons soon.
Today I'm posting graphics from 2 meteorologists.
And every day or two I'll post two more experts.
You can compare and contrast their forecasts.
Today I'm starting with Crown Weather and CSU.
Why those two?
Because I have always admired their forecasts.
I admire and respect many others.
I'll post them too over the next few weeks.
Today I'm listing 5 Factors to remember.
Again I'll post more factors in future posts.
1. El Nino is not expected to be a factor this year. Neutral or more likely La Nina conditions will exist and it is possible if not probable that La Nina may show up as we move into August and September. IF that happens, it would favor a more active, dangerous hurricane season.
Note No El Nino doesn't mean La Nina ... maybe it stays Neutral but La Nina is looking possible.
2. Sea Surface Temperature forecasts continue to be warmer in areas that would produce hurricanes.
3. Forecasts for areas in Africa that may have more rainfall than normal could reduce the impact of SAL (Saharan Dust) but remember that SAL predictions are always prone to error and seasonally it usually disappears at the worst time as we move towards late August and early September. While watching it reign in May and June and July we often end up with a plethora of headlines giving the general public a sense of a false reality that gets ripped out from under them when SAL begins to disappear at the worst time possible Currently SAL may me mitigated by moist conditions nearby in Africa. Think of this as being told you don't need to wear a "face mask" and then being told you "could if you want" then being told you will not be allowed in a store without one and then being told it's better to wear one when out in public around others. Again remember this ...things change and often they sometimes change fast.
4. Signs in the Indian Ocean show we will have a strong hurricane season. Why watch the Indian Ocean? Because what happens in the Indian Ocean impacts Africa and what happens in Africa directly begins to impact us as we move into the heart of the Hurricane Season.
5. The forecast is for a lack of Wind Shear across many areas for this coming Hurricane Season that would allow strong tropical waves to develop into hurricanes without being torn apart by shear. We often see incredibly formed tropical waves make it across the Atlantic and yet as they battle what is wind shear they succumb to the shear the way a young, seemingly healthy young football player on the field during practice collapses as mentioned previously. Very often a very moist, large, messy tropical wave turns into a poorly organized tropical storm and then finding a fast sweet spot develops into a hurricane closer to our side of the world. But strong shear or negative conditions can literally topple the named storm everyone is worried on the way a large, tall, improperly secured crane topples over when hit with stronger than expected winds.
Below is Hurricane Debby's NOAA report.
Wind shear suddenly strengthened.
And Hurricane Debby toppled over like a falling crane.
There's more to the story but this is the official one below.
This old forecast track shows why people were worried.
An image of Debby in her "better days" before...
...wind shear began to strengthen.
I mention this as even now..
Shear Forecasts are often iffy ...
...and often Shear develops fast.
Or wind shear suddenly disappears.
Wind shear forecasts favor a busy hurricane season.
During El Nino wind shear protects some areas.
Especially the Caribbean and the GOM.
This year we cannot rely on that wind shear to be there.
I'll give more reasons I am concerned on the 2020 Hurricane Season later as we move into May and the concern for early season storms forming before June 1st becomes a reality.
But for now the 5 factors listed above are what I want you to take away from today's blog.
Someone I leaned to trust and enjoy reading is Rob from www.crownweather.com that I commonly refer to as "Crown Weather" as I learned over time and across many avenues of social media (as we go way back) to appreciate his cautiousness and when he shows concern to take it seriously. In 2017, 2018 and 2019 his Pre Season Maps were spot on and he nailed the locations Hurricane Florence would threaten eventually landfall as well as Hurricane Michael months ahead of the peak of the hurricane season. The year that Maria and Irma traipsed across the Atlantic, slamming into islands in their path and scaring everyone on the East Coast and Florida he drew those possible tracks in his Pre-Season maps. It really doesn't get better than that for picking up on current and long term trends and applying them to predicting where hurricanes may track and make landfall.
www.crownweather.com is a pay service, you can write him and ask for payment or donation information but it's better than the average information you will find on Twitter, Instagram, your family WhatsApp Group or where ever you get your general information. He posts regularly online on Twitter with excellent information. Note the people on TV in your local viewing area do a great job but honestly they rarely veer away from the official NHC or the CSU forecast shown below and until a hurricane is headed directly towards your town their information is informative yet basic. When you want better information with more details sometimes you gotta pay for it or really know how to find it online.
The link to Rob on Twitter
@crownweather (easy to remember)
If you see this picture you have the right person.
Understand Rob is a very good writer.
A good communicator.
It's good for meteorologists to be able to ...
...clearly communicate information.
That's important.
I'm using a few of his images below.
When I said shear could be low....
.... that would be a problem.
If the forecast verifies.
Note the areas below in blue.
If shear is low there....
It means waves turn into named storms.
And are not blown apart by shear.
How strong they would get is a question.
But the potential is there for strengthening.
Again graphics from Crown Weather.
Below Average Wind Shear is not good.
It allows hurricanes to form.
Often those regions in the Carib have high wind shear.
The wind shear protects the Carib and ....
......inhibits then from strengthening.
This would favor storms that track West...
..... into Central America.
Or they could drift over the Yuctan...
...as storms often do.
Then strengthen in the GOM
Once in the GOM ..someone gets hit.
Understand?
@bobbistorm on Twitter for any questions.
Below we have "peak of the season"
Note this would favor Caribbean/GOM storms.
Also storms coming at Florida from many directions.
Storms such as Cleo that came up from Cuba.
Or any hurricane that hits from the ESE...
...heading WNW
Look at Cleo coming up from Cuba.
Then look at the graphic below.
It shows how that could happen.
Every hurricane is different.
Every year is different in some way.
The graphic below I've shown before.
Rob will fine tune it over time.
When you understand the shear problem shown above.
As well as where warm water may be.
Steering currents.
You will better understand the graphic below.
It shows areas of the coastline in danger.
In danger as per our early forecasts.
2020 has been a year of unusual events....
...that pop up fast suddenly.
Things change.
From Covid 19 to Tornadoes in the South.
So use it as a guide early on.
East Coast would be vulnerable.
Note below CSU shows this also.
And GOM is a concern.
The Caribbean is a high concern.
Note also CSU points this out below.
So moving on to the CSU report.
Lots of detail and more academic.
But you can understand if it you go slow.
And many of you here know your lingo.
Several important point are mentioned by Phil.
An old picture of Phil with Dr. Gray.
Phil carries on Dr. Gray's legacy.
He's older now but still has very youthful looks.
You can follow him on Twitter.
@philklotzbach
Graphics from the CSU forecast that I find particularly relevant to remember.
The first graph below shows you in bright red lines how this season's potential seems to be way above average for trouble, exceeding Climatology. Basically saying higher odds on it being stronger than most average seasons based on "climo" as we often refer to it. Generally climo wins out over hype and worry when watching tropical waves forming into hurricanes, but in sometimes forecasts are heaped high with positive factors vs negative factors and we all know this 2020 how we prefer negative results to positive ones so keep that in mind. You may read the whole report linked below to understand this graphic better, but you can look at it and see that the forecast for 2020 currently exceeds the normal climo probabilities.
Please refer to the link below and look for this graphic in the report towards the end of the long report. I say long in a good way as year back when I would carefully read Dr. Gray's report I would learn much from reading and studying the details. Sometimes the forecast verified all too well and other times such as in 1997 when the "Mother of All El Ninos" came out of nowhere much like today's Covid-19 and the forecast was a bust it ended up being a very slow hurricane season. But, whether the forecast verifies or is a bust or is somewhere in between the point of reading the long, detailed report is that you learn much on the whys and hows a season is impacted by specific factors and trust me you will know more than you knew before you took the time to read it. And, thanks to Covid-19 and our new world where many of us can't go to work or the hairdresser or the Mall or the movies or meet Aunt Dolly or Sally at our favorite dining spots we have a bit more down time and can read up and research topics we love to learn more about so if you got the time... sit down with a cup of coffee or tea or whatever you enjoy and read and learn. Spoiler alert...when you click on this image or go to the report it shows that all areas are at an enhanced risk this year but especially the East Coast 92% and the Caribbean 94% much higher than the average year. Also refer to his report as sometimes he includes the Florida Peninsular in the "East Coast" statistics so be sure what he means when he uses terminology that may not jive with your vision of the Hurricane Coast.
I'm concerned that the Year of Covid-19 could evolve into The Year of Deadly Hurricanes and that is not hype and no I cannot tell you if this will be the Bertha to get the name finally retired or Dolly will or won't be a Category 5. But what I can tell you is that this year's current forecast based on current conditions portends a deadly hurricane season for someone and we may have multiple deadly Major Hurricanes as we had when Irma and Maria came close together.
I am mentioning Irma because the sort of wild rush to evacuate Florida and the search for safe shelters will be severely negatively impacted by the ongoing Covid-19 crisis. How so? Well most of us are low on funds and even those who had money put away for an emergency have less money put away for an emergency. Many people are out of work, travel is discouraged and contact with people at rest stops or buying gas are now health concerns and as for food chain lines.... as I said earlier things change fast these days. We've been told food chains would not be impacted yet currently several chicken, pork and meat producers have had to close up because people tested positive. They will open up again in theory soon but at times our "food supply chain" may be impacted so keep that in mind and hopefully it will not be a factor.
We were told to stop "hoarding food" because the food chain lines will be fine. We were also told not to go out often, so we aren't so much hoarding as buying food that will last for several weeks before we buckle up into our hazmat suits or begin putting on our masks or gloves and our now every present hoodie covering our head and venturing out in search of pasta and tuna fish and whatever produce that we hope will last more than a week or two. Perhaps you are the type that isn't wearing a mask nor wearing gloves and going shopping as you were while trying to maintain a safe distance from people ...especially those who are coughing or who look sick.... you still may have to wait in line a long time come July or August to get into a store to buy hurricane supplies way longer than you normally do when you think "this is crazy" because what if we hit a peak again in August and stores limit shoppers and you may get online for your local Publix blocks away from the actual store. I'm not saying this will happen. I am saying this could happen and you MUST figure it into your Hurricane Season Preparation this year.
So if you are at the store this week buy an extra few tins of tuna and put them in a box and do not use them. Buy an extra peanut butter and hide it away the way you would a candy bar from your hungry teenagers. Buy an extra bottle of bleach or any disinfectant supplies you can get your hands on for the Hurricane Season. And, I hate to say this but it is very possible that this virus goes on deep into 2021 as Pandemics similar to the Spanish Flu don't just disappear overnight when it's convenient for us or when the calendar year changes so if you don't use the tuna by November 30th, 2020 feel free to transfer your Hurricane Supplies to your Covid-19 supplies.
I'll continue to show different predictions for this Hurricane Season and add layers of perspective for you to think on and research yourself over the next month. I'll talk on Analog Years given by many including the years that I believe are Analog Years and show old hurricanes from those years. Thanks for letting me rant yesterday as I needed to get that off my chest and be able to move on to being serious about the Hurricane Season because to be honest we really need to take this Hurricane Season seriously because we've seen from recent tornadoes, severe weather, hail and earthquakes Mother Nature is not in quarantine or socially distancing and she has ripped people's homes that they were staying home in apart and tossed them wildly off their foundations in deadly tornadoes. That's heartbreaking but it should be a stark reminder to you that not only can't you reason with hurricane season you can't reason with Mother Nature either.

Hurricane Chris Out to Sea. Beryl Remnants Remain a Possible Problem. DIY Ideas and Hurricane Prep. Busy Year So Far and It's Early. Do You Have a Hurricane Plan?
HURRICANE CHRIS
Only cities that need to worry about wind from Chris.
Looks good...doesn't it?
Far off shore.
Not bothering Bermuda or East Coast.
Just cruising along NE at 22 MPH
Put it in motion.
Hurricane Chris is churning up the waters of the Atlantic far away from the Atlantic coast to have any impact other than high surf and small craft should probably be aware it's there. If you have a small craft you are usually aware of the weather as it's the first thing you need to check before taking the small craft out into the water obviously. So even though you can go online and see these stunning visual images of a big hurricane off the coast know it's staying off the coast.
The truth is unless you live on Cape Cod you aren't worried about Chris and they aren't really worried as they have winter storms that are way stronger than hurricanes. That's what they ALWAYS tell me, my friends up in those parts. "Oh we have real Nor'easters stronger than hurricanes" and yeah that's because they die before they get up to your cold waters. Kind of clueless in ways as what they often experience is not what people experience on the Pacific Islands that are lashed by 185 MPH winds or the hell that Hurricane Maria created when it sandblasted an island in the Atlantic before going on to disrupt life in Puerto Rico where life is still being put back together. Yes, I know your Nor'easters are awesome but nothing compared to a slow moving West Indies Hurricane. Nuff said on that.
So in truth no one really cares that much about Chris other than from a visual and academic perspective. In truth last night it looked to be a Major Hurricane, Cat 3 yet was kept at Cat 2 with long discussion explaining why they kept it at Cat 2 strength when it appeared to be a Major hurricane. For the record books it was a Cat 2 with a Cat 3 appearance. What's 5 MPH between friends? It's an impressive hurricane here too early making 2018 a now busy hurricane season with good ACE numbers so let's store those headlines about a dead hurricane season away and put them in a file named 2018 Hurricane Season. Yes, some people actually have files; some keep newspapers and others keep intricate folders on their computers. Hurricane Trackers and Chasers should really be renamed for that they truly are and I've done it so you can include me in for my own chasing days. We are Hurricane Stalkers. That's the real honest way to put it, yet it's not so politically correct so we call ourselves "Storm Chasers" but really people are just stalking the storm trying to touch it's energy, understand it and get pictures of it to store away in their cache of memories.
And, when Chris goes out to sea........ people look elsewhere to see what's next.
So what's next?
The remnants of Beryl remain a question. I'd use the word quandary but I've used that already so let's just say it's a big question. Currently at Noon it's still 50/50 and you ask why I bet? Yet there is a huge about of convection over a large area traveling en masse off the East Coast following in the wake of Hurricane Chris. Waters some what cooler than they were before Chris visited and not very warm to begin with in July. Well, warm enough for something but not for real trouble to happen. We are on the C storm looking for the D storm in early July. If this continues we will need to worry about hurricanes that play peek a boo with cold fronts and high pressure systems in this part of the Atlantic as those powers that be often bring real trouble to the coastline; trouble not just high surf and riptides.
So Chris exits stage right.
Models have been playing with Beryl's remnants.
The presence of a storm of any kind...
...keeps the ante up and the NHC is monitoring it.
Note on the 5 day that X is orange.
The 2 day is shown below.
You can see the ripple in the winds on Earthnull
Models below show the weak concern.
Weak as in currently nothing is there.
But in general the water is hot in the Bahamas.
And it's quite warm just offshore.
The Gulf Stream is always warm.
Especially in July.
Note the 3 model slivers below show two things worth noting. One is the presence of the remnants of Beryl trying to form into some sort of closed low. Those remnants actually loop about much like Chris did for a day or two. Chances are only 50/50 and it's worth remembering Beryl was always enigmatic so expect more odd behavior if it does really try and form. Also note the strength of the high to it's right over the Atlantic.
As models keep throwing out this close in solution.
The NHC will continue giving it medium odds.
50/50 in the 5 day.
It would be pretty amazing for X Beryl to pull that off.
Elsewhere........
A wave near Africa exits and enters the stage.
Short window to stay alive.
But so far not expected to develop.
Note Global Hazards Map highlights the area still.
Lastly leaving you with some Hurricane Prep reading.
Yellow X Over NC - Development Near OBX? 10 - 20% Chances Something Could Develop. Questions on Cool Water By Africa in the East Atlantic and Why You Shouldn't Really Care. Makes Great Click Bait and a Researcher's Dream But Close In Hurricanes Could Happen in 2018. Despite the Headlines Waves Keep Rolling Off of Africa. Come September We Need to Remember Climo Usually Wins.
Woke up this morning to the site of a Yellow X on the NHC 2 Day map just to the West of me. I always joke that Greensboro gets more weather than Raleigh and obviously that includes yellow 10% areas of possible development from the NHC. Some models spin this up and spit it out into the Atlantic where it moves in Derecho manner across the open water zooming out to sea. Some models do have it following the warmth of the Gulf stream close up the coast but off the coast sucking in as much energy (available heat from warm water close in) and sliding up towards the banks of Newfoundland. The EURO is more bullish on this system than the GFS that does not see anything of consequence evolving. Remember that as it will be interesting to see which model read this set up better than the other. Well, interesting for those of you who find that interesting ;)
So let's look at the models.
Using the 850 mb relative vorticity version here of Euro model to try and show the exact "center" of this possible tropical disturbance I'm showing three images below. Again, it is not currently tropical but it may present itself as tropical later in the forecast period. Confusing I know but it's the only real show in town so going to explain it as best as I can in a simplistic way. The orange splotch over NC is the yellow X with 10% chances over North Carolina.
It then shoots it out near OBX into the Atlantic.
Kind of like spitting out a watermelon seed...
It's on it's way the next day.
Fast moving blip.
Could it attain TD status?
Possibly.
Water there is warm.
Remember this map above for later discussion.
For our purposes today there is warm water there.
It has a very narrow window to develop.
Sustainability is a big word used often these days in other arenas of discussion, but going to use that word here today in relation to tropical development as water needs to be warm enough to sustain tropical development. Kind of that simple. It also needs low shear that will not interfere with development. If you have a well developed low pressure area move over the warm waters off of the Carolinas where there is low shear it has a window where it could develop into a more truly tropical system.
There is something about the way these low pressure systems over land and how they evolve as they hit the warm water that sometimes spins up a named storm. This is a perfect example of how a set up can produce a tropical system given the right circumstances. And, this is why I am more worried about the water temperatures close in to the coast on our side of the world in June and July than I am about the water temperature near Africa that is historically still cold this time of year. Again, sustainability is a factor and evolution is the process that can make a difference when it comes to Homegrown Tropical Systems. The set up is not ideal, but it is there enough to warrant the low numbers given it from the NHC; that being 10% in the next two days and 20% in the next five days.
Perhaps the GFS feels there is too much shear there?
Currently today there is severe weather on the maps.
Watches and warnings up from NWS.
Live News feed on Twitter.
There are three points to take away from this blog today. The first is that we currently have a "Yellow X with 20%" chances on the NHC map for a possible, fast forming, fast moving system that could take on tropical characteristics. Many are asking if this could be Beryl, other's see a Tropical Low or Tropical Depression while others see nothing of significance forming or to talk about. Time will tell who is right, but Dabuh watches the surf along with the weather so anything that brings the surf on is of significance to him.
Two the over concern with the cool water temperatures out near Africa in late June is a matter of Academic significance and scientific discovery. It matters little how cool or hot the water in the East Atlantic is if you live in coastal towns that have a history of home grown development close in giving little warning time before landfall and making huge coastal impacts. Over the very warm waters of the GOM or Florida hot water and low shear close in can be the best set up available for rapid intensification of a developing tropical system. Watch how fast Wilma intensified just off shore of the Yucatan and one can only imagine what it would be like to have had satellite imagery of the Labor Day Hurricane that formed in the Bahamas in 1935.
When we talk about ACE it is basically the sum total of the intensity of the hurricane season as a whole. That often includes intense hurricanes that form in warm pools of water in the Eastern Atlantic early on and far away that tend to turn NW out into open waters becoming beautiful ocean spinners. They are also beautiful in that they spare the East Coast and the Islands direct hits such as last year's Hall of Fame winners Maria and Irma. There are years where ACE is high and hurricanes happen everywhere yet make landfall nowhere. Those are golden years for hurricane researchers to learn more about the various stages of development and steering conditions that impact hurricanes. However they often stay far away from land, yet oddly years with overall low ACE can present dangers close in that leave their imprint on the coastal towns for years and the list of those storms is long. So yes on one level we will (in theory) have less long tracking CV Hurricanes moving WNW slowly at 15 MPH giving us photogenic images of true Atlantic Hurricanes. On the other hand it means nothing as to what the chances are for landfalling hurricanes in Florida, South Carolina, North Carolina or the Mid Atlantic States in the same places slammed by Hurricane Sandy that came up out of the Caribbean, across Cuba and surfed her way North over the very warm Gulfstream. A look at 1985 is another excellent example of just this sort of problematic years where hurricanes made landfall often yet most formed close in and few formed near Africa. The Southwest Carib was mostly shut down as this year could be as well as shear there is high. Two systems formed out near Africa and made it across, yet many formed closer in and there was a traffic jam of landfalling hurricanes.
Ask anyone who went through Gloria....
...how memorable 1985 was.
Keep in mind Gloria formed in the heart of the season.
When water by Africa is at it's warmest.
Gloria formed September 16th.
Climo almost always wins.
It's really not about quantity but quality.
Thankfully it could lessen the danger to the Caribbean.
Cooler waters by Africa means less early hurricanes.
The Islands are rebuilding slowly.
Florida is covered with blue tarps still.
They can use a break in tropical action.
But it means little to the the SE, GOM or NE.
Look at the map below.
June, July and August are about W of 55 Degrees.
Usually, most years.

Again ACE is an academic term and we love to throw it about online and use it as a measure for how "active" a Hurricane Season may be or how busy it was in retrospect; it also makes great headlines and click bait in quiet times such as June and July. In real time you need to worry on what may be knocking at your door after rapidly developing close in the way Andrew did after wheezing it's way across the Atlantic constantly in danger of having the NHC pull the plug only to blow up in waters closer to the coast the same way the Labor Day Hurricane did in 1935. There was NO Ace until late August in 1992 when Andrew developed, yet we spent years rebuilding in South Florida after Andrew.
Yesterday Allan Huffman posted his thoughts on this topic of water temperatures being below normal close to Africa, yet pointing out that the cool water pool of water ends at 55 degrees West. Is the cup half full or half empty? There are two ways to look at every question and we need to not let our guard down about the 2018 Hurricane Season that will hopefully, thankfully not be as active as 2017.
Watch the discussion that followed.

With all it's annoyances....
...Twitter is a great place for real time discussion.
Rob from www.crownweather.com is 100% correct and people need to not let their guard down because there is a current anomaly of cold water near Africa as it doesn't mean that the danger of hurricanes forming close in (especially in this particular year I'll add) do not pose a serious threat and people need to prepare properly for the 2018 Atlantic Hurricane Season. It also doesn't mean that come September we will have to remember hurricanes form in the East Atlantic the way Gloria did in 1985. I'll write on this more over the next few days. But it's true and Bastardi mentions it often that no models showed the dramatic decline of warm water in the distant Atlantic and that makes me wonder how good the models really are when it comes to long term forecasting especially with regard to this year. Often they are great, however in swing years as this one may be if the much whispered El Nino develops, but some years have contrasting signals and their own unique problems so I beg you to take this year and every year seriously and do what you do need to do to get a hurricane plan set up for how you would deal with a landfalling hurricane or very, slow moving strong Tropical Storm that may dump copious amounts of rain and slam your area with tornadoes. Let's leave the scientific terms used for evaluating a season to the academics and the researchers and prepare as if this is the year that Andrew or Gloria is going to come knocking on your door!
Oh and #3 .... despite cool pools of water by Africa and high levels of Saharan Dust the waves over Africa keep on coming. The last one, the newest one earned a purple splotch on the maps we watch to see where development could happen. A little smirk there yesterday on that last wave. The one behind the smirky one has quite the structure, however it's going to plop down in mighty cold water way too early to expect development just yet.

If you are wondering how I am dealing with a Yellow X over my head... I made a tropical breakfast of Avocado Toast and Mango Slices ;) A girls got to do what a girl's got to do . . . and am loving the cooler weather on the balcony listening to the excited birds singing while waiting on the rain to fall.
