Caribbean - Central America Weather

[Gustywind]

A strong line of showers is just pulsing in my location... nice gusts since 1 minute!

For info given Meteo-France Guadeloupe, gusts were approaching 34 knots yesterday in some localities especially St François, le Moule and the airport of Le Raizet (where Meteo-France is located). That's why i was a bit "surprised" by these nice gustywinds.

[Gustywind]

The other wave approaching the EC continue to gain nice convection. Looks like unstelled weather should continue at least Monday even Tuesday Thus this wave continue to be fairly well organized with cyclonic turning and exhibits nice cyclonic curvature. We should continue to monitor carefully this twave becoming active...
