Tropical Weather Discussion for North America, Central America
Gulf of America, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
0830 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 10N15W to 03N18W. The ITCZ
continues from 03N18W to 03N39W. Scattered moderate and isolated
strong convection is within 300 nm on either side of the ITCZ.

GULF OF AMERICA...

A cold front extends southwestward from central Florida to a 1016
mb low near 25N96W, then stationary to near Veracruz, Mexico.
Fresh to strong winds are N of the front over the NE Gulf. Gentle
to moderate winds prevail over much of the remainder of the
waters, except reaching fresh speeds west of the Yucatan
peninsula. Seas are in the 5-7 ft behind the front, and 2-4 ft
ahead of the front.

For the forecast, fresh to strong N to NE winds and moderate to
rough seas will follow the cold front through Mon. On Tue, the
western portion of this boundary will gradually dissipate over the
central and western Gulf, while the eastern portion will resume
moving southward into Cuba and the Yucatan Channel. Gentle to
moderate southeasterly winds will return to the Gulf on Thu.

CARIBBEAN SEA...

Moderate winds, and seas of 4-5 ft prevail E of 75W. Gentle
winds, and seas of 1-3 ft, prevail W of 75W.

For the forecast, a weaker than usual pressure gradient will
support mainly gentle to moderate winds over much of the forecast
waters through the week. Fresh to strong NE winds may develop Tue
night and Wed across the Windward Passage and at the lee of Cuba
associated with a late- season cold front moving across Cuba.

ATLANTIC OCEAN...

A cold front extends from 31N75W to central Florida. Fresh to
strong winds, and seas of 4-7 ft are found W of the front. Light
to gentle winds, and seas of 3-4 ft, are noted E of the front to
72W. High pressure dominates the remainder of the discussion
waters, where gentle to moderate winds, and seas of 4-7 ft,
prevail.

For the forecast west of 55W, fresh to strong N to NE winds and
rough seas will follow the front as it reaches from Bermuda to the
Florida Straits by late this afternoon, and from 31N60W to
central Cuba by Tue afternoon. Winds will begin to diminish Tue
night as the front stalls and dissipates along 22N by late Wed.
High pressure will settle in between northeast Florida and Bermuda
in the wake of the front. Large N swell may linger near the
dissipating front Wed into Thu, including waters near the Windward
Passage.
