Tropical Weather Discussion for North America, Central America
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 1800 UTC surface analysis and satellite imagery through
2315 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Liberia near 07N11W
to 00N16W. The ITCZ continues from that point to 03S30W to the
coast of Brazil near 03S45W. Widely scattered moderate convection
is from 01S-07S between 25W-50W.

GULF OF MEXICO...

A 1029 mb high is centered over South Carolina near 34N82W. A
surface ridge extends SW from the high to the Bay of Campeche near
20N96W. 10-15 kt easterly winds are over the Gulf of Mexico with
strongest winds over the Straits of Florida. Fair weather is over
the entire Gulf. In the upper levels, a ridge is over the Gulf
with very strong subsidence.

A cold front will move over the NW Gulf Sat night followed by
fresh to strong NE winds and building seas. Gale conditions could
develop behind the front for the waters near Tampico Sun night.

CARIBBEAN SEA...

A stationary front extends from NW Hispaniola near 20N73W to
Nicaragua near 13N83W. Scattered showers are within 60 nm of the
front. 15-20 kt N winds are N of the front. 20-25 kt NE winds are
along the coast of N Colombia. 10-15 kt tradewinds are over the E
Caribbean E of 75W. Scattered showers are over Puerto Rico,
Hispaniola, and Jamaica. Isolated moderate convection is inland
over N Colombia. In the upper levels, strong subsidence persists
over the Caribbean Sea and Central America suppressing deep
convection.

The front will gradually weaken through late Fri. Elsewhere
generally moderate trade winds will persist across the Caribbean
and tropical Atlantic west of 55W through early next week.

ATLANTIC OCEAN...

The stationary front enters the waters near 31N60W and extends
SW to 26N65W to a 1014 mb low near 27N71W. A cold front extends S
from the low to NW Hispaniola near 20N73W. Scattered moderate
convection is N of 23N between 60W-69W. Scattered showers are
elsewhere within 180 nm E of the front. A 1028 mb high is centered
over the central Atlantic near 35N36W. A 1018 mb low is over the E
Atlantic near 31N21W. Another 1016 mb low is over the Canary
Islands near 29N17W.

Over the W Atlantic, winds and seas will gradually diminish
tonight as the low slowly weakens and drifts E toward 26N65W
through late Fri. High pressure will build off the U.S. east coast
in the wake of the front through Sun, then move E ahead of the
next cold front expected to move off the NE Florida coast early
next week.
