...TROPICAL WAVES...

An Atlantic Ocean tropical wave is along 16W from 12N southward,
moving westward at 15 knots. Precipitation: the wave is moving
through the area of the ITCZ. The wave is surrounded by ITCZ
precipitation.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the northern coastal sections
of Guinea near 11N15W, to 08N33W. The ITCZ continues along
07N38W to 05N42W to 05N50W. Precipitation: widely scattered
moderate to isolated strong is in clusters from the Equator to

to 10N between 13W and 47W.

GULF OF MEXICO...

A surface trough is analyzed south of Louisiana. A second
surface trough in the far SW part of the Gulf of Mexico near the
coast of Mexico. Precipitation: isolated moderate is in the
coastal waters and coastal plains of the U.S.A. from 28N
northward between the Florida Panhandle and 94W.

Broad surface anticyclonic wind flow spans the rest of the Gulf
of Mexico.

A ridge will dominate the Gulf of Mexico during the next several
days. Gentle to moderate easterly winds, and 2 to 4 ft seas, are
expected through Sunday.

CARIBBEAN SEA...

A weak upper level inverted trough is in the SW corner of the
Caribbean Sea, between 80W and Nicaragua. The monsoon trough is
along 09N from 74W in Colombia beyond Costa Rica. Precipitation:
scattered to numerous moderate to strong is within 30 nm to 45
nm on either side of a line that runs from 10N77W to 17N84W.

A 700 mb inverted trough extends from the Yucatan Channel to the
eastern coast of the Yucatan Peninsula to Belize and the Gulf of
Honduras. Precipitation: widely scattered moderate, isolated
strong is from 17N northward and from Jamaica westward, in the
waters between Haiti, Cuba, and Jamaica.

The tropical wave along 57W will cross the Windward Islands
later today. The wave will reach the central Caribbean Sea on
Thursday night. The tropical wave along 36W will reach the
Lesser Antilles on Friday. Fresh to strong trade winds will
continue in the south central Caribbean Sea through Friday, and
then expand in coverage during the upcoming weekend.

ATLANTIC OCEAN...

A cold front passes through 32N75W to 29N75W. A surface trough
continues from 29N75W, to the Bahamas near 25N76W, to the coast
of Cuba near 23N80W. Precipitation: isolated moderate to locally
strong covers the area that is northeast of the Bahamas from 24N
northward, and from 60W westward.

Upper level cyclonic wind flow covers the Atlantic Ocean from
27N northward and 33W eastward. Rain showers are possible in the
area of cyclonic wind flow.

The current surface trough will drift eastward, N of 27N,
through Thursday, and then it will weaken. Atlantic Ocean high
pressure will build across the region by the end of the week.
Fresh to occasionally strong easterly winds will pulse, in the
waters north of Hispaniola, at night.
