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 0000 UTC surface analysis and satellite imagery through
0415 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Sierra Leone near
07N12W to 04N15W. The ITCZ continues from 04N15W to 01N30W to
the coast of Brazil near 01S47W. Scattered moderate to isolated
strong convection is from 05N to 03S between 30W and 45W.

GULF OF MEXICO...

A cold front has recently exited the Gulf of Mexico. A 1023 mb
high is centered over the NE Gulf near 30N87W. Surface ridging
and dry air is over the Gulf. Elsewhere, scattered moderate
convection is over central Texas and NE Mexico. 5-10 kt
anticyclonic winds are in the vicinity of the high. 15-20 kt SE
winds are over the NW Gulf.

A new cold front will move into the northern Gulf Wed evening,
and reach from the Florida Big Bend to northeastern Mexico Thu
morning. The western part of the front will become stationary
and weaken through late Thu night, while the rest of the front
will weaken as it exits the SE Gulf late Fri. Weak high pressure
in the wake of this front will slide eastward across the
northern waters through Sat night.

Smoke from agricultural fires over SE Mexico and Central America
may reduce visibility over the Bay of Campeche.

CARIBBEAN SEA...

The tail end of a cold front extends from central Cuba near
23N79W to the the Yucatan Peninsula near 20N90W. Scattered
showers and thunderstorms are noted over the N Yucatan Peninsula
N of 19N. A 1007 mb low is centered over N Colombia near 10N74W.
Scattered moderate to isolated strong convection is over
N Colombia. Scattered showers are over Panama and Costa Rica.

The cold front along the northwest boundary of the basin will
wash out and dissipate Tue. High pressure extending from the
central Atlantic to the NW Bahamas will maintain fresh to strong
trade winds over the south-central Caribbean through Tue before
gradually weakening Wed through Fri.

Smoke from agricultural fires in Central America will continue to
reduce visibilities over the Gulf of Honduras for the next few
days.

ATLANTIC OCEAN...

A cold front over the W Atlantic extends from 31N67W to central
Cuba near 23N79W. Scattered showers are within 60 nm of the
front. A 1025 mb high is over the central Atlantic near 29N47W
producing fair weather. Scatterometer data shows fresh to strong
winds N of 30N just ahead of the front, and back along 80W where
the local pressure gradient was tight. Moderate to fresh winds
were noted elsewhere west of 60W.

The southern portion of the front S of the Bahamas will
transition to a weakening stationary front Tue and dissipate Tue
evening. The remainder of the front will shift east. Another
cold front will move off the southeastern U.S. coast and into
the W Atlantic Thu, preceded by fresh to strong southerly winds
beginning Wed. The front will reach from near 31N76W to east-
central Florida Fri morning, and weaken as it reaches from the
central Bahamas to NW Cuba Sat. Scattered showers and
thunderstorms are expected ahead of this front.
