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

.SYNOPSIS...Fresh to strong northeast to east winds will pulse
offshore of northern Colombia each night and morning well into
next week due to the pressure gradient resulting from the
combination of high pressure over the western Atlantic and
relatively lower pressure over northern Colombia and the south-
central Caribbean. Rough seas can be expected with these winds.
Elsewhere, the gradient will also support moderate to fresh
trade winds along with moderate seas over the remainder of the
basin through the period. Scattered to numerous showers and
thunderstorms associated with a trough are over the western
Caribbean from 14N to 20N between 81W and 85W. Gusty winds are
possible with this activity as it may linger into late tonight.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A dissipating stationary front extends from near
31N58W southwestward to 26N67W. Weak high pressure off east-
central Florida will shift southeastward through early Mon in
response to a cold front that will move off the northeast
Florida coast this morning. The front will reach from near
Bermuda to Sebastian Inlet, Florida by early Mon. The eastern
portion of the front will continue eastward and reach from 30N55W
to 27N70W by early Tue, while the portion west of 70W starts to
lift back north as a warm front. High pressure will shift
eastward off the Mid- Atlantic coast during the week, with its
related gradient supporting moderate to fresh northeast to east
winds and moderate seas over the region, with large northwest
swell following the front southeast of Bermuda. Looking ahead,
winds and seas will diminish west of 70W by Wed, ahead of front
expected to move off the northeast Florida coast early Thu. The
front will reach from Bermuda to the Straits of Florida by late
Thu night, followed by fresh northeast winds and building seas.
