CORRECTED CARIBBEAN SEA SECTION

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 
0000 UTC. 

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal sections of Liberia
near 06N11W, to 04N20W. The ITCZ continues from 04N20W to 01N26W
02N34W, to the Equator along 50W. Precipitation: scattered 
moderate to strong rainshowers are from 02N to 08N between 11W 
and 21W. rainshowers are possible elsewhere from 10N southward 
from 60W eastward.

...DISCUSSION...

GULF OF MEXICO...

An upper level trough is pushing a cold front through the Gulf of
Mexico, now passing through the Florida Panhandle, into the N
central Gulf waters, into and beyond NE Mexico. Rainshowers are
possible to the NW of the 28N80W 23N97W.

A stationary front cuts across Andros Island in the Bahamas,
through the Straits of Florida, to the Yucatan Peninsula of
Mexico. Precipitation: scattered moderate to strong rainshowers
cover inland and coastal areas of Central America, from 13N in
Honduras to 21N in the Yucatan Channel between 86W and 96W in the
Isthmus of Tehuantepec of southern Mexico.

The current cold front will reach the SE Gulf on Saturday, where 
it will stall and dissipate. High pressure will build in the wake 
of the front and prevail through Tuesday. 

CARIBBEAN SEA...

A stationary front cuts across Andros Island in the Bahamas, 
through the Straits of Florida, to the Yucatan Peninsula of 
Mexico. Precipitation: scattered moderate to strong rainshowers 
cover inland and coastal areas of Central America, from 13N in 
Honduras to 21N in the Yucatan Channel between 86W and 96W in 
the Isthmus of Tehuantepec of southern Mexico. Isolated moderate 
rainshowers cover the area from Cuba to 25N between 72W in the 
Atlantic Ocean and 85W in the Gulf of Mexico. 

A NE-to-SW oriented middle level trough extends from the north 
central Caribbean Sea into the SW corner of the area. 
Precipitation: Scattered moderate to strong rainshowers cover 
the area from 05N to 11N between 72W and 78W, mostly in Colombia 
and possibly a bit in NW Venezuela.

A surface trough is moving through the Mona Passage from 15N to 
21N. Precipitation: rainshowers are possible from 16N to 22N 
between 64W and 69W. 

Moderate to fresh trade winds will prevail in the south central 
Caribbean Sea. Gentle to moderate trade winds are expected 
elsewhere.

ATLANTIC OCEAN...

A stationary front passes through 32N69W to Andros Island in the 
Bahamas, through and beyond the Straits of Florida. 
Precipitation: rainshowers are possible from 20N northward from 
60W westward.

A central Atlantic Ocean cold front covers the area that is from
22N northward between 44W and 58W. A 1018 mb low pressure center
is near 29N49W. Precipitation: widely scattered moderate
rainshowers are from 22N to 30N between 42W and 47W. rainshowers
are possible elsewhere from 20N northward between 30W and 60W.'

The current stationary front will dissipate this evening. A 
second cold front will move into the northwest waters Fri night, 
reach from 31N74W to southern Florida Sat night, then slowly 
dissipate by Sun morning. A third cold front will push south of 
31N Sun. This front will reach from 30N65W to the northern 
Bahamas Mon night and from 25N65W to the central Bahamas on Tue 
night.
