and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas
...GULF OF MEXICO...
Strong southeast winds are noted from the Straits of Florida to
the Texas coast, ahead of a cold front approaching the coast of
Texas from the west. The front will move east and reach from near
Mobile Bay to the southwest Gulf tonight, and then stall from the
Florida Big Bend area to the northwest Yucatan peninsula by late
Monday. Strong winds will follow the front Sunday, reaching gale
force off Tamaulipas and Veracruz. Scattered to numerous showers
and thunderstorms will rake the northern Gulf along the front
through tonight. Winds and seas will diminish through Monday as
the front weakens. The front will lift north through late Tuesday
into Wednesday, ahead of another cold front moving into the
northwest Gulf early Thursday. Gales are possible again off the
Mexican near Tamaulipas and Veracruz by late Thursday.
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...
A ridge located north of the area is supporting pulses of fresh
to strong east to southeast winds near the Gulf of Honduras,
easterly trade winds off Colombia and northwest Venezuela and a
smaller area south of Cabo Beata in southern Dominican Republic.
Winds will diminish over these areas later this morning, but will
repeat again tonight. Fresh trade winds and seas 6 to 8 ft are
expected over the central Caribbean through late today along with
fresh northeast winds into the Windward Passage. Winds and seas
diminish across the region from Monday through the middle of
next week as the high pressure weakens and shifts east, leaving
mainly fresh trades off Colombia and gentle to moderate breezes
...SW N ATLANTIC INCLUDING THE BAHAMAS...
Ridging along 30N continues to support fresh to strong trade
winds south of 25N west of 70W from the Turks and Caicos across
the southern Bahamas to southeast Florida, with 5 to 8 ft seas in
open waters. Elsewhere moderate to fresh southeast winds are noted
with 3 to 5 ft seas. This pattern will persist into Monday.
Southeast to south return flow will increase off the coast of
northeast Florida through late Monday as a weakening cold front
approaches the area from the eastern Gulf of Mexico. The front
will stall along the Florida coast by early Tuesday then become
diffuse. Winds and seas diminish late Tuesday through mid week
as weak high pressure builds west along roughly 28N.
