Does this have a realistic shot of developing? I really want there to be a S storm this year since it shares my name. :D

It reminds me of last year's Tomas in terms of the location.

This must be what GFS sees replace 96L in the SW Carribean in a week or so?

This was the 2 PM TWO for this area.

A BROAD AREA OF LOW PRESSURE HAS FORMED ABOUT 350 MILES
EAST-SOUTHEAST OF TRINIDAD IN THE SOUTHERN WINDWARD ISLANDS.
CLOUDINESS AND SHOWERS ASSOCIATED WITH THIS LOW HAVE BECOME A
LITTLE BETTER ORGANIZED AND THE POTENTIAL FOR DEVELOPMENT HAS
INCREASED. THIS SYSTEM HAS A LOW CHANCE...20 PERCENT...OF BECOMING
A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. REGARDLESS OF
DEVELOPMENT...CLOUDINESS AND HEAVY RAINS WILL LIKELY SPREAD OVER
NORTHERN VENEZUELA AND THE SOUTHERN WINDWARD ISLANDS DURING THE
NEXT FEW DAYS.

Very interesting formation. It's rare to have a tropical low develop nearly inland along the coast of South America. I'm curious to see what track this takes.

Hi Caribbean friends,islandguy246 and Hylian Auree. I moved both posts that you made at the models thread to this discussion thread as both were not related to model runs. :)

Keep us informed about the weather related to this system that may impact your islands.

If 97L develops it will be a E Caribbean problem w/o passing 70W IMO! :D

very interesting indeed! Reminds me of Tomas too Luis.
We had all prepared last year for it, and it took a huge jog NW.
I see that more models are showing this jog. Yet I can't ignore those that show a direct path for Trinidad. Guess it's gonna be a long night watching and waiting.......

Plenty of rain will be the biggest threat for the SE Caribbean islands from this as of right now.

8 PM TWO

SHOWERS AND THUNDERSTORMS HAVE DECREASED IN ASSOCIATION WITH A BROAD
AREA OF LOW PRESSURE LOCATED SEVERAL HUNDRED MILES EAST-SOUTHEAST
OF THE SOUTHERN WINDWARD ISLANDS. ENVIRONMENTAL CONDITIONS ARE
MARGINALLY FAVORABLE FOR SOME SLOW DEVELOPMENT OF THIS DISTURBANCE
DURING THE NEXT COUPLE OF DAYS. THIS SYSTEM HAS A LOW CHANCE...20
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS
AS IT MOVES SLOWLY WEST-NORTHWESTWARD. REGARDLESS OF DEVELOPMENT...
CLOUDINESS AND HEAVY RAINS COULD SPREAD OVER THE WINDWARD ISLANDS
AND NORTHERN VENEZUELA DURING THE NEXT FEW DAYS.

Looks like I can rest comfortably tonight.
Never fails to amaze me how things get blown apart down here.
There might be a chance of reorganization at some point, but nothing to lose sleep over.

Yes,shear is too strong right now as long that big upper low is around. But let's still watch it as that trough is forecast to lift out by early next week.
