Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1715 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of Sierra
Leone near 08N13W to 03N19W. The ITCZ continues from 03N19W to
00N29W to the coast of Brazil near 04S39W. Scattered moderate to
isolated strong convection is from 02N-07N between 14W-18W.
Widely scattered moderate convection is from 06N-05S between
24W-54W.

GULF OF MEXICO...

As of 22/1500 UTC, a cold front extends from Port Saint Lucie
Florida to Tampa Florida to Mobile Alabama. The front is void of
precipitation. 10-20 kt SE return flow is over the Gulf of Mexico
S of the front. Strongest winds are over the NW Gulf.

A developing low pressure system over the U.S. southern plains
will pull fresh to strong SE to S winds across the basin through
Thu. The low will drag a cold front across the northern Gulf Thu
through Fri. A second cold front will move into the NW Gulf Fri
night, then extend from S Florida to the SW Gulf Sun.

CARIBBEAN SEA...

10-15 kt trade winds are over the Caribbean Sea. Scattered
showers are over the Leeward Islands, Puerto Rico, and south
of Hispaniola. Elsewhere, isolated moderate convection is over
N Colombia and NW Venezuela.

E to SE winds will increase over the Gulf of Honduras tonight,
then continue through Fri, in response to a cold front
moving across the NE Gulf of Mexico. A ridge over the western
Atlantic will maintain fresh to strong trade winds over the S
central Caribbean tonight through Sun. Moderate to fresh trades
are expected elsewhere Thu through Sat.

ATLANTIC OCEAN...

As of 22/1500 UTC, a cold front is over the W Atlantic from
31N62W to 25N70W to central Cuba near 22N78W. Scattered
moderate convection is within 150 nm S of the front E of 70W.
A reinforcing cold front is over the W Atlantic from 31N73W to
Port Saint Lucie Florida near 27N80W. This front is void of
precipitation. A 1027 mb high is over the central Atlantic
near 37N33W. The tail end of a dissipating cold front is over
the E Atlantic from 31N29W to 27N36W. Scattered showers are
over the Canary Islands.

The leading W Atlantic cold front will slowly push SE today,
then dissipate from SW to NE tonight through Thu. Fresh to
strong SW winds will precede the front N of 27N this morning.
A cold front will head E from the SE United States coast Fri
through Sat morning. Strong S to SW winds are expected ahead
of this front N of the Bahamas Thu and Thu night. Another cold
front will move off the coast of northern Florida late Sat
night, then extend from near Bermuda to S Florida Sun.
