Africa near 10N14W and continues west-southwestward to 05N19W.=20
The ITCZ extends from 01N23W to 02S44W. Scattered moderate=20
isolated strong convection is noted from 00N to 04N between 03W=20
and 13W. Widely scattered moderate convection is observed from 02N
to 04N between 25W and 45W.
...GULF OF AMERICA...
High pressure is building into the Gulf waters, currently centered
over the NW Gulf. Fresh to strong winds, and seas of 6-9 ft=20

For the forecast, fresh to strong winds and rough seas will=20
diminish today. High pressure will build in the Gulf, supporting=20
moderate to locally fresh S to SE winds over the western and=20
central Gulf, and gentle to moderate winds in the eastern basin=20
through this weekend. A surface trough will develop over the=20
Yucatan Peninsula and move into the Bay of Campeche nightly=20
through Sun, increasing winds to fresh to strong speeds in the=20
Peninsula adjacent waters. The next cold front may enter the=20
northwestern basin early next week.=20
...CARIBBEAN SEA...
Please refer to the Special Features section above for
information on a Gale Warning.
A cold front is over the Yucatan channel. Moderate winds prevail
over the far NW Caribbean, with seas in the 3-4 ft range. Fresh to
strong winds, and seas of 8-9 ft are over the south central
waters, with moderate to fresh winds elsewhere S of 15N and E of
78W. Gentle to moderate winds, and seas of 2-5 ft, cover the
remainder of the Caribbean waters.=20=20
For the forecast, fresh to strong E to NE winds offshore of=20
Colombia and Venezuela will pulse to gale force offshore of=20
Colombia each night and early morning into early next week. A cold
front entering the northwestern Caribbean will support moderate=20
to fresh NE winds and moderate seas in the wake of the front=20
through this morning. The front will dissipate today. Fresh to=20

31N51W and extends SW to near 27N55W. Scattered moderate and=20
isolated strong convection is within 90 nm SE of the front. A=20
surface trough is SE of the front, with an area of scattered=20
moderate and isolated strong convection in the vicinity of the=20
trough. Fresh to strong winds are found N of 26N and E of the=20
front to near 47W. Subsiding W to NW swell ushered in by these=20
features is supporting 8-locally 12 ft seas over the waters N of=20
