-95L emerged off Africa high 90% chance as heads West
-Area just emerging off Africa 40% chance as heads more W/NW behind Rene.

E Pac:
Area well off SW Mexico now 80% chance formation as heads out to sea.

They always build once they move away from FL. Can't buy a tropical system.

Fri 11Sept 5pEDT/4pCDT TD19 (Formally 96L):
Winds 35mph(55km/h)
Moving WNW 8mph(13km/h)
Pressure 1009mb
A small spin developed in 96L earlier today and is evident on Miami radar, clouds have improved as well. TS Watch issued for Jupiter Inlet to N of Ocean Reef. The storm is only 4mph away from being classified as a TS and named and it's possible this happens before crossing FL tonight. Up to a few inches of rain and breezy for S FL is all though. Can't rule out a small brief tornado spin up here or there. Then it enters the Gulf while sending up showers into parts of Western FL. NHC forecast currently has a 70mph TS coming near LA/MS general region Monday/Tuesday, subject to change.

As Levi points out in below tweet, having radar this close we can see the low level (LLC) spin (not much convection/storm with it, located E of Miami between Miami and the main convection rain blob) and the mid-level (MLC) spin (the main convection spinning). Think of these like a double layer chocolate cake...bottom portion LLC, top section MLC. Storms prefer to be more aligned so no rapid intensification expected before moving over S FL tonight.

TD19:
Sat 12Sept 8aEDT/AST,7aCDT:
Winds 35mph(55km/h)
Moving W 9mph(15km/h)
Pressure 1004mb
About to emerge off S FL into the Gulf.
Storm likely lopsided for awhile with most convection on the East to maybe North side.
The slow journey over the Gulf will mean prolonged Surge and rain effects on it's approach towards Central Gulf coast region. Hurricane status near landfall is possible.

Watches:
-East FL coast Watches canceled.
-TS Watch for Ochlockonee River to Okaloosa/Walton Co. line.
-TS and even Hurricane Watch may be extended/issued later today or Sunday.

Sat 930aEDT: Up to 3” per hour rain rates are possible Keys and extreme S FL:
