Erin Downgraded to Tropical Depression... Invest 92L at 10%
Mystery Invest... 92L
I call it that cause it's a mystery to me why we have been watching it for days.
Seems sort of black and white to me. Nothing there, nothing really has been there and possibly never will be there. It could and that should be in gray... could... possibly...form a small circulation that moves off towards TX/MX border.. maybe.
The water vapor loop also shows a big dry slot moving down into the Gulf of Mexico.
See the really dry arrow of darkness moving down into the Gulf of Mexico across Oklahoma and down through Texas? That is not exactly conducive to a developing tropical storm that feeds off warm, moist air vs a Mid August Cold Front going all the way into the GOM.
Nada... nothing happening. Infact the NHC has lowered it's chances to 10% with a yellow circle. When my friend and I saw that today we high fived each other. I mean how long can you watch TWC hype a non-existent system and a wayward ULL traveling across the Caribbean and the Gulf of Mexico with no real signs of circulation and no real convection.
This is an exercise in tropical insanity. Okay, a couple of days ago the models were bullish. We never give up on any wave when a model or two of importance pay attention. We are no longer watching the waves we are it seems watching the models.
Invest 92L may go down in history as the most watched Invest in history if it doesn't develop into a weak TD somewhere before it hits land.
As for Erin... it's been downgraded to a Tropical Depression
Weak, very weak.
Already talk that it might become a remnant low... but it has a long way to go if it can stay together so we can write it off another day if it indeed is going to die out.
Here's the actual discussion explaining why the NHC is watching it for future development down the line IF it stays alive and how and why Erin might move more to the WNW and get under neath a stronger high IF it survives.
From 5 PM Discussion.
ERIN HAS CONTINUED TO MOVE TOWARD THE NORTHWEST OVER THE PAST FEW HOURS...LIKELY DUE TO THE INFLUENCE OF A DEEP-LAYER LOW SOUTH OF THE AZORES. RECENT SATELLITE IMAGES SHOW THAT ERIN HAS TURNED BACK TOWARD THE LEFT...AND THE INITIAL MOTION ESTIMATE IS 315/11. THE TRACK MODEL GUIDANCE IS INSISTENT ON ERIN TURNING BACK TOWARD THE WEST-NORTHWEST IN THE NEXT DAY OR SO AS IT COMES UNDER THE INFLUENCE OF A SUBTROPICAL RIDGE BUILDING TO THE NORTH AND ANOTHER CUTOFF LOW CURRENTLY LOCATED NEAR 24N/49W. IF ERIN SURVIVES LONG ENOUGH...IT WILL LIKELY TURN BACK TOWARD THE NORTHWEST INTO ANOTHER WEAKNESS IN THE RIDGE THAT DEVELOPS BY 72 HOURS.
From 11 PM Discussion.
TROPICAL DEPRESSION ERIN DISCUSSION NUMBER 13 NWS NATIONAL HURRICANE CENTER MIAMI FL AL052013 1100 PM AST SAT AUG 17 2013 THE LOW-LEVEL STRUCTURE OF ERIN HAS RECENTLY DEGRADED WITH THE CIRCULATION BECOMING ELONGATED FROM NORTHWEST TO SOUTHEAST. IN ADDITION...THE ASSOCIATED DEEP CONVECTION IS FARTHER AWAY FROM THE CENTER. AN ASCAT PASS FROM 2310 UTC SUGGESTED MAXIMUM WINDS OF 30-35 KT...AND GIVEN THE DECREASING DVORAK ESTIMATES AND THE RECENT SATELLITE TRENDS...30 KT IS CHOSEN AS THE INTITAL INTENSITY. SOUTHWESTERLY SHEAR...DRY AIR...AND MARGINAL SEA SURFACE TEMPERATURES SHOULD CAUSE ERIN TO BECOME A REMNANT LOW WITHIN 48 HOURS. THE LATEST NHC INTENSITY FORECAST FOLLOWS THE TREND OF THE PREVIOUS ADVISORY AND IS SIMILAR TO THE GLOBAL MODEL GUIDANCE...WHICH SHOW ERIN DEGENERATING INTO A TROUGH OF LOW PRESSURE BY 72 HOURS. ASCAT DATA SUGGEST THE CENTER OF ERIN HAS MOVED WESTWARD DURING THE PAST FEW HOURS BUT A LONGER-TERM MOTION IS 290/10. A SUBTROPICAL RIDGE REBUILDING OVER THE CENTRAL ATLANTIC APPEARS TO HAVE CAUSED THE LEFTWARD TURN AND SHOULD STEER ERIN ON THIS GENERAL COURSE FOR THE NEXT COUPLE OF DAYS. MODEL GUIDANCE HAS SHIFTED NOTABLY SOUTHWARD ON THIS CYCLE...WITH A FEW MODELS EVEN SHOWING A DUE WESTWARD TRACK. ASSUMING A WEAKER ERIN WOULD BECOME MORE STEERED BY A STRONGER LOW-LEVEL RIDGE...THE NHC FORECAST IS ADJUSTED TO THE SOUTH.

So if you are wondering if that's all there is and we are going from summer to winter without any hurricane season you are so, so wrong.
Nooo... it's just still early and the season begins to ramp up this week and as the say going August
Get Ready, September Remember.
June -- too soon. July -- stand by. August -- look out you must. September -- remember. October -- all over.
There's a reason that's an old saying... it's true!
So, where is the color of the tropics? The life? The energy? Have we moved from summer straight into winter without any Hurricane Season? The Color is Coming...
So I wouldn't write off the season just yet because before September we haven't had some big Major Cane.
I'll say it ONE MORE TIME... this week when it's quiet in August... GET READY.

A good read is cut and pasted below from the Librarian at the NHC.
Sweet Tropical Dreams...and tomorrow when you wake up... go out and buy what you need just in case. Makes some lists and then go out and have a great day.
Remember...September is around the corner!
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&..............just do it!
