I give this a 25% chance of becoming a named storm. I'll start having faith in the tropics again once things actually happen.

5:30 AM TWO

AN AREA OF DISTURBED WEATHER ASSOCIATED WITH A SURFACE TROUGH AND
UPPER-LEVEL LOW IS CENTERED ABOUT 225 MILES NORTH-NORTHWEST OF
PUERTO RICO. THIS SYSTEM HAS CHANGED LITTLE IN ORGANIZATION EARLY
THIS MORNING...HOWEVER...ENVIRONMENTAL CONDITIONS ARE GENERALLY
FAVORABLE FOR SOME DEVELOPMENT OVER THE NEXT COUPLE OF DAYS AS IT
MOVES SLOWLY NORTHWARD.

8:05 AM TWD:

THE ATLANTIC OCEAN...
AN ELONGATED SFC TROUGH ANALYZED FROM 22N63W TO ERN CUBA
DOMINATES THE SW PORTION OF THE ATLC BASIN. THERE ARE A FEW
EMBEDDED VORT MAXES ALONG THIS STRETCHED OUT TROUGH AXIS.
HOWEVER...THE MAIN ENERGY APPEARS TO BE NEAR THE UPPER LOW
LOCATED JUST N OF THE DOMINICAN REPUBLIC. THIS INTERACTION IS
PRODUCING SCATTERED SHOWERS AND TSTMS S OF 24N BETWEEN 62W-72W.
PRECIP APPEARS MOST CONCENTRATED JUST N OF THE LEEWARD ISLANDS
FROM 19N-21N BETWEEN 63W-65W. ENVIRONMENTAL CONDITIONS ARE
GENERALLY FAVORABLE FOR SOME DEVELOPMENT OVER THE NEXT COUPLE OF
DAYS AS IT MOVES SLOWLY NORTHWARD.

Its pretty far south. The models have shifted so that the first trough misses 93L but it does not move WNW very fast.
Any further south and it is going to start having land interaction problems.

well... the favorable conditions lasted for 12 hours. Looks like northerly shear.

The SW Caribbean has little shear though, typial of an October la nina. We just do not have a surface feature there

I think there is still very loose turning at the 93L position north of Puerto Rico.

I don't think so... it's hard to tell in the midst of all this mystery weather :wink:

93 is becoming better organized this afternoon.
We may have a depression by tomorrow morning.
With the high building over the system, it should move W or WNW for a few days.
