.SYNOPSIS...An Atlantic surface ridge prevails N of the area.
The pressure gradient between the ridge and lower pressure over
northern South America is supporting fresh to strong E winds in
the south-central Caribbean. A deep layer trough will dig
southward across the western Caribbean Mon night through Fri,
supporting active weather E of 80W Tue through Fri. Fresh to
strong E to SE winds will develop in the central Caribbean Tue
and shift eastward through Thu while diminishing to mostly fresh
speeds. Smoke due to agricultural fires in Central America
continues across the Gulf of Honduras, but continue to thin out.
