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

.SYNOPSIS...A stationary front extending from eastern Cuba to
near the border between Nicaragua and Costa Rica will weaken and
dissipate during the weekend. Fresh to locally strong N winds
are behind the front with seas to 8 ft. These winds conditions
will gradually diminish through Sun. A tightening pressure
gradient between developing low pressure in the southwestern
Caribbean and high pressure building over the southeastern
United States will promote fresh NE winds in the Atlantic
Passages and in the lee of Cuba on Sat, and moderate to fresh NE
to E winds and moderate seas in E swell will develop across much
of the basin Sun through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from near 31N66W to 26N72W and
to 23N74W, where it transitions to a stationary front to eastern
Cuba. A reinforcing cold front extends from near 31N73W to near
Vero Beach, Florida. This front will reach from near 31N72W to
SE Florida by early this afternoon. Gale force west to northwest
winds are expected behind this front beginning this afternoon N
of 30N between the front and 77W. Fresh to strong winds are
expected elsewhere on either side of the front N of 26N. The
front will merge into the first front from near 31N64W to 26N69W
and to near the Windward Passage by late tonight, at which time
the gale conditions are expected to diminish. Seas of 12 to 15 ft
are expected with the gale winds, and seas of 8 to 12 ft
elsewhere N and NE of the Bahamas through late tonight. Long-
period N swell with this front will produce rough seas for areas
north of 25N by Sat morning. Rough seas will shift eastward
through this weekend, and seas greater than 8 ft will continue
into next week for areas east of 65W.
