A very vigorous cold front, for this time of year, extends from the panhandle of Florida south-southwest to the Bay of Campeche. Numerous showers and thunderstorms, some severe, are associated with the front north of 23N. The pressure gradient between the front and the Bermuda High is causing SW winds up to gale force today.

The cold front will exit the Gulf tonight and winds will quickly subside on Sat. Weak high pressure will subsequently build in over the Gulf promoting quiescent conditions Sun through Tue. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...
