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 northern coastal sections
of Sierra Leone near 08N13W to 05N28W. The ITCZ continues from
05N28W to 06N40W to the coast of N Brazil near 04N51W. Scattered
moderate convection is from 02N-07N between 00W-15W. Isolated
moderate convection is from 03N-13N between 15W-41W.

GULF OF MEXICO...

As of 25/1500 UTC, a cold front entered the NW Gulf of Mexico
near Galveston Texas. A prefrontal squall line is noted on radar
from New Iberia Louisiana near 30N93W to the NW Gulf near 28N95W.
Scattered moderate to strong convection is within 30 nm of the
squall line. Elsewhere, scattered showers are over S Florida
and the SE Gulf. The remainder of the Gulf has SE return flow
with mostly fair weather.

The cold front will progress over the northern Gulf today.
The front will stall and lift northward on Thu. A strong cold
front will move into the NW Gulf waters Sun morning bringing
fresh to strong northerly winds across the basin.

CARIBBEAN SEA...

Scattered moderate convection is along the coast of Central
America from Honduras to Panama. Elsewhere, scattered showers
are over the Virgin Islands, Puerto Rico, and Hispaniola mostly
due to the tail end of a cold front over the W Atlantic.

High pressure building behind a cold front north of the region
will increase winds and seas in the central Caribbean through
Thu. Moderate to fresh trade winds will prevail across most of
the area Thu night through Sun.

ATLANTIC OCEAN...

A cold front extends from 31N57W to a 1016 mb low pressure area
near 26N61W to N of Puerto Rico near 20N65W. Scattered moderate
convection is E of the front N of 23N between 52W-57W. A 1038 mb
high is centered over the Azores near 41N30W dominating the E
Atlantic with surface ridging.

The Atlantic cold front will move slowly eastward today, then
become stationary Thu. Fresh to locally strong NE winds
associated with the front will prevail over the western Atlantic
through early Thu. Northerly swell behind the front is expected
to impact the Atlantic waters and local passages beginning
tonight through Fri.
