Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...High pressure extends from the central Atlantic
westward along 25N to 72W. 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.
