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.

...TROPICAL WAVES...

A tropical wave is partially over Africa along 12W from 01N-12N,
moving W at 15 kt. The wave shows up well in the satellite
imagery and in the model diagnostic data. Widely scattered
moderate convection is from 03N- 06N between 11W-15W.

An Atlantic tropical wave is along 32W from 01N-15N, moving W at
20 kt. Widely scattered moderate convection is from 03N-08N
between 29W-36W.

An Atlantic Ocean tropical wave is along 48W from 01N-14N, moving
W at 15-20 kt. Isolated moderate convection is from 02N-14N
between 45W-51W.

A Caribbean Sea tropical wave is along 68W from 02N-15N, moving W
at 15 kt. Scattered moderate convection is from 05N-13N between
62W-70W.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of Guinea-
Bissau near 12N15W to 08N18W to 06N22W. The ITCZ extends from
06N22W to 06N31W, then resumes W of a tropical wave near 05N34W to
05N46W. Besides the convection mentioned in the tropical wave
section, scattered moderate convection is from 03N-07N between 36W-
44W.

GULF OF MEXICO...

As of 08/2100 UTC, a cold front extends from S Mississippi near
30N88W to the NW Gulf near 27N92W to S Texas near 27N97W.
Scattered showers are within 60 nm of the front N of 27N.
Scattered moderate convection is in the warm section over the NE
Gulf from 28N-31N between 83W-87W. Elsewhere, scattered moderate
convection is over central and south Florida S of 29N.

A broad low pressure area over the southern U.S. will maintain
moderate southwest to west winds across the NE and north-central
Gulf through Sun. A weak cold front in the NW Gulf will stall and
weaken in the north central Gulf overnight. A stronger cold front
will move across the NW Gulf Mon, then weaken in the northern
Gulf Tue and Wed.

CARIBBEAN SEA...

10-20 kt tradewinds are over the Caribbean Sea with strongest
winds over the south central Caribbean, and weakest winds over the
far SW Caribbean. Besides the convection associated with the
tropical wave, widely scattered moderate convection is over Puerto
Rico, E Hispaniola, and Cuba. Clusters of scattered moderate to
isolated strong convection is inland from Honduras to Panama.

A weak ridge north of the area will support moderate to locally
fresh trade winds across most of the Caribbean Sea during the
next several days. Fresh to strong trade winds are expected in
the south central Caribbean Sea through Thu, with building seas
to 9 ft.

ATLANTIC OCEAN...

Widely scattered moderate convection is over the W Atlantic N of
25N and W of 75W. A large 1032 mb high is centered over the
central Atlantic near 37N38W. Of note in the upper levels, an
upper level low is centered over the W Atlantic near 25N64W.
Scattered showers are within 300 nm of the center.

A ridge will dominate most of the W Atlantic through Mon while a
low pressure area will remain over the SE of United States.
Moderate southerly winds are expected across the Atlantic the
next few days. A weak cold front will reach the waters off NE
Florida by late Tue, then lift N of the area by Wed.
