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 0600 UTC surface analysis and satellite imagery through
1045 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal areas of Sierra
Leone near 08N13W to 04N20W. The ITCZ continues from 04N20W to
01N33W. A surface trough is from 08N34W to 02S35W. The ITCZ
continues again from 00N36W to the coast of Brazil near 03S43W.
Widely scattered moderate convection is from 00N-04N between 12W-
30W. Scattered moderate to isolated strong convection is from 3N-
08S between 30W-48W.

GULF OF MEXICO...

As of 07/0900 UTC, a 1018 mb high is centered over the NE Gulf of
Mexico near 29N87W. A cold front extends from Cape Canaveral
Florida to Venice Florida, then continues to the E Gulf of Mexico
near 25N87W. A dissipating stationary front continues to N of
Corpus Christi Texas near 28N97W. Scattered showers linger over
S Florida, and the SE Gulf. Scattered moderate convection is over
S Texas and NE Mexico from 25N-27N between 96W-100W. Scattered
moderate convection is also over the Bay of Campeche from 18N-21N
between 95W-97W. South of the front, light to gentle east-
southeast winds are noted. Gentle to moderate northeasterly winds
are north of the boundary.

The front will weaken and gradually dissipate today, with high
pressure building in its wake. A thermal trough will develop each
night over the Yucatan Peninsula, and support pulses of fresh to
locally strong winds in the SW Gulf at night. Smoke and haze from
ongoing agricultural fires in Mexico could reduce visibilities in
the western Gulf and the Bay of Campeche.

CARIBBEAN SEA...

15-25 kt tradewinds are over the Caribbean Sea with strongest
winds along the coast of N Colombia. Scattered moderate to
convection is over the N Yucatan Peninsula. Scattered moderate to
isolated strong convection is over S Guatemala, the Gulf of
Honduras, and W Honduras. Scattered moderate to isolated strong
convection is over NW Colombia, and central Venezuela. In the
upper levels, a ridge is over the Caribbean with upper level
moisture.

Fresh to strong easterly winds will prevail in the south- central
Caribbean and the Gulf of Honduras through early Wednesday before
diminishing. Smoke and haze from ongoing agricultural fires could
reduce visibilities north of Honduras.

ATLANTIC OCEAN...

A cold front is over the W Atlantic from 31N72W to Cape Canaveral
Florida near 28N81W. Scattered moderate convection is within 60
nm of the front. A 1022 mb high is over the central Atlantic near
25N53W. Another 1022 mb high is over the E Atlantic near 26N31W.

The W Atlantic cold front will shift eastward through Wed. High
pressure will build across the forecast area in the wake of the
front.
