from 07N to 19N W of 55W, the N Atlantic from 19N to

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W
.SYNOPSIS...A weak Atlantic surface ridge extends westward along
25N and into the N Bahamas. The associated pressure gradient
between the ridge and lower pressure over SE Mexico is
supporting pulsing fresh to strong E to SE winds across the Gulf
of Honduras, and fresh to locally strong E winds in the south-
central Caribbean. The winds in the Gulf of Honduras will
diminish to fresh speeds overnight. The fresh to strong E winds
in the south-central Caribbean 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 appears to be thinning out.

Synopsis for the the SW N Atlantic including the Bahamas
.SYNOPSIS...A cold front is analyzed N of 30N, while a high
pressure ridge extends along 25N and into the N Bahamas.
Scattered showers and thunderstorms prevail ahead of the front

southward into the waters offshore of Georgia and NE Florida
early Mon, and move southeastward and stall from near 31N72W to
SE Florida late Tue. A trough will develop southeast of the
weakening front and extend into the central Bahamas early on
Wed, and drift eastward through Fri night. Low pressure is
expected to form along the trough near 24N68W Thu evening and
move NE through Fri night.
