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
0930 UTC.

...ITCZ/MONSOON TROUGH...

The Monsoon Trough extends from the African coast near 11N15W to
03N20W. The Intertropical Convergence Zone continues from 03N20W
to the South American coast near 04S39W. Scattered moderate and
isolated strong convection are S of 03N and E of 08W and from 01N
to 06N between 15W and 20W. Isolated moderate convection is south
of 02N between 37W and 47W.

...DISCUSSION...

GULF OF MEXICO...

High pressure centered over the western Atlantic extends westward
across the northern gulf coast, supporting moderate to locally
fresh east to southeast winds across most of the gulf basin
this morning, except fresh to strong winds over the SE Gulf and in
the vicinity of a surface trough over the eastern Bay of Campeche.
Isolated showers are over the eastern gulf in low level moisture.
Otherwise, fair weather dominates the gulf basin. Over the next
24 hours a cold front will approach the northwestern gulf and will
enhance shower and thunderstorm activity along the Texas coast
and possibly the nearby offshore waters.

CARIBBEAN SEA...

High pressure north of the region supports moderate to fresh
easterly trades over the majority of the Caribbean basin this
morning. The only exception is locally strong winds along the
northwestern coast of Colombia. Scattered showers cover the
Greater Antilles, with numerous showers in the vicinity of the
southern portion of a surface trough that extends from the
Atlantic, across Puerto Rico, to near 17N67W. Over the next 48
hours the surface trough will be absorbed by a developing broad
area of low pressure north of the eastern Caribbean. This will
help to disrupt the trade wind flow over the northeastern
Caribbean. Little change is expected elsewhere.

...HISPANIOLA...

Scattered showers and isolated thunderstorms are across the
island this morning as enhanced moisture associated with a
stationary front to the north continues to spread southwest over
the area. This shower and thunderstorm activity will continue
through at least this evening.

ATLANTIC OCEAN...

A stationary front extends from 31N57W to 28N64W, then transitions
to a warm front to near 24N71W. A surface trough lies just east of
the stationary front with an axis from 29N58W to 25N61W.
Scattered moderate convection is from 26N to 31N between 58W and
68W. Another surface trough extends from 23N63W southwestward
across Puerto Rico. Numerous showers and isolated thunderstorms
are within 120 nm of either side of the trough axis. High
pressure of 1024 mb centered near 35N42W dominates the central
Atlantic. A surface trough extends from 31N22W to 25N29W. No
significant convection is noted. Over the next 24 hours showers
and thunderstorms will continue near the stationary and warm front
as the front transitions to a frontal trough through Tuesday,
then develops into a broad area of low pressure on Wednesday.
