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

.SYNOPSIS...An 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 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.
