Noticed some rotation in this cluster of convection just off the NE tip of South America.

Zoom in and speed up the animation.......

I noticed that too but it looks like it has blown off.


2009 is a bad year for satellite spotting.

This area should approach us in the islands especially Martinica and even Guadeloupe tonight Sanibel. An yellow alert should be issued at 11 AM in Guadeloupe for a risk of strong showers/tstorms...

Whats invest 97L on NRL ?

NRL got confused and 97E is the same as 97L. Which means that 97L doesn't exist.

Wouldn't surprise me if this Windwards convection blows off again tonight.

This one has the worst tropical characteristics, but it's in the best position for potential:

Nothing there but a tropical wave in the eastern Caribbean interacting with an upper low. Upper winds not favorable for development.

[Recurve]

Upper low spinning over PR in water vapor. Convection along old front/trough through Bahamas. Drier air heading toward SFL from the west. You can almost feel a hint of fall. Except it's still 90F.

In the Atlantic Ocean the remnants of Hurricane Fred continue to produce periodic thunderstorm activity in the eastern Atlantic Ocean about midway between the Cape Verde Islands and the Lesser Antilles. It appears that the low level circulation is getting weaker as it moves westward at 15 mph. At this time regeneration into a tropical depression or tropical storm is unlikely.

An area of low pressure is producing moderate thunderstorm activity just to the west of the Cape Verde Islands. Environmental conditions are marginally favorable for development as the low moves westward away from the islands.

A tropical wave just to the east of the Lesser Antilles is producing scattered showers and thunderstorms in Barbados, the Grenadines and Grenada. This wave moves west spreading the rain north and westward through the remainder of the Lesser Antilles over the next two days.

Large system, but hopefully convection has diminished a bit since this morning. We should experience some possible strong showers locally and isolated tstorms. Yellow alert have been maintained for the night, but should be dispruted tommorow morning...meaning a return in green alert . I have some infos about this twave
Latest measurements of Meteo-France during this episode:

Pretty modest amounts have been reported in Guadeloupe: 10 to 20 millimeters in numerous areas of Grande-Terre and also in vicinity of les Saintes, Marie-Galante, and la Désirade. Whereas, 30 to 50 millimeters have been estimated in the north tip of the island, near Ste-Rose, Deshaies.
