Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A weak Atlantic surface ridge prevails N of the
area. The associated pressure gradient between the ridge and
lower pressure over northern South America is supporting fresh
to strong E winds in the south-central Caribbean. These winds in
the will shift eastward to offshore of NW Venezuela through Tue
night and diminish early on Wed. 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.
