Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W
.SYNOPSIS...A weak and narrow Atlantic ridge extends westward
along 24N/25N and into the NW Bahamas. The associated pressure
gradient between the ridge and lower pressure over SE Mexico is
supporting fresh to strong E to SE winds across the Gulf of
Honduras, and fresh to locally strong E winds in the south-
central Caribbean. Winds in the Gulf of Honduras will become
moderate to fresh today through Mon. Fresh to strong winds will
pulse at night in the Gulf of Venezuela and offshore Colombia
through early Mon then shift eastward to offshore of NW
Venezuela through Tue night. A vigorous middle to upper-level
trough will dig southward across the western Caribbean Mon night
through Thu, and support very active weather over central
portions E of 80W Tue through Thu. Smoke due to agricultural
fires in Central America continues across the Gulf of Honduras
and areas of the northwestern Caribbean.

Synopsis for the the SW N Atlantic including the Bahamas
.SYNOPSIS...A weak frontal trough extends from 31N56W
southwestward to 26N69W, while a narrow high pressure ridge
extends E to W to the south of the trough along 24N/25N and into
the NW Bahamas. The trough will shift eastward through late Sun
as it weakens further, allowing the ridge to build modestly into
the region E of 72W Mon and Tue. Scattered showers and
thunderstorms will move from the NW waters southeastward through
this evening, ahead of an upper level trough. Behind this
feature, a new front will sink 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 Thu night. Low pressure is expected to form along the
trough near 24N68W Thu evening and move NE.
