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
0510 UTC.

...TROPICAL WAVES...

An Atlantic Ocean tropical wave is along 29W/30W from 15N
southward, moving westward 20 knots. Precipitation: the wave is
moving through the area of nearby ITCZ precipitation.

An Atlantic Ocean tropical wave is along 44W/45W from 16N
southward, moving westward 15 to 20 knots. Precipitation: the
wave is moving through the area of nearby ITCZ precipitation

A Caribbean Sea tropical wave is along 62W/63W, from 19N
southward, moving westward 20 to 25 knots. Precipitation:
isolated moderate to locally strong is from 21N southward
between 60W and 70W.

A Caribbean Sea tropical wave is along 77W/78W, from Jamaica
southward, moving westward 15 to 20 knots. The monsoon trough is
along 09N74W 07N80W, beyond 08N85W in the eastern Pacific Ocean.
Precipitation: scattered to numerous strong is in the coastal
waters of Panama that are from the monsoon trough northward,
between the tropical wave and 80W; and from 10N southward
between the coast of Colombia and 80W.

A tropical wave is moving through the SW corner of the Gulf of
Mexico, along 96W/97W, from 20N southward, moving westward 15 to
20 knots. This tropical wave is moving through an area of upper
level anticyclonic wind flow, and SE wind flow from 700 mb to
500 mb. Precipitation: isolated moderate to locally strong is in
the coastal waters of Mexico from 22N to the Mexico coastal
border with Texas.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal border sections of
The Gambia and Senegal near 13N17W,to 11N22W, 08N26W, 09N29W,
and 09N35W. The ITCZ continues from 09N35W, to 08N42W, 05N46W,
and 06N53W. Precipitation: widely scattered to scattered
moderate and isolated strong is from 02N to 10N between 22W and
35W; and within 90 nm to the south of the line that runs from
09N60W 08N53W 07N46W. Isolated moderate is elsewhere from 11N
southward from 60W eastward.

GULF OF MEXICO...

A tropical wave is moving through the SW corner of the Gulf of
Mexico, along 96W/97W, from 20N southward, moving westward 15 to
20 knots. This tropical wave is moving through an area of upper
level anticyclonic wind flow, and SE wind flow from 700 mb to
500 mb. Precipitation: isolated moderate to locally strong is in
the coastal waters of Mexico from 22N to the Mexico coastal
border with Texas.

A surface ridge extends from a 1021 mb high pressure center that
is near 29N85W, in the NE corner of the Gulf of Mexico, to the
coastal border of Texas and Mexico.

A surface ridge will prevail in the Gulf waters through the
weekend. Moderate to fresh E to SE winds are expected across
most of the basin through Tuesday.

CARIBBEAN SEA...

An upper level trough extends from a cyclonic circulation center
that is about 120 nm to the SSW of Jamaica, through the Windward
Passage, and more northeastward to 32N57W in the Atlantic Ocean.
Precipitation: isolated moderate to locally strong is in the
Caribbean Sea from 16N northward from the Mona Passage westward.

A Caribbean Sea tropical wave is along 62W/63W, from 19N
southward, moving westward 20 to 25 knots. Precipitation:
isolated moderate to locally strong is from 21N southward
between 60W and 70W.

A Caribbean Sea tropical wave is along 77W/78W, from Jamaica
southward, moving westward 15 to 20 knots. The monsoon trough is
along 09N74W 07N80W, beyond 08N85W in the eastern Pacific Ocean.
Precipitation: scattered to numerous strong is in the coastal
waters of Panama that are from the monsoon trough northward,
between the tropical wave and 80W; and from 10N southward
between the coast of Colombia and 80W.

Fresh to strong trade winds will prevail in the south central
Caribbean Sea through the weekend. The Wind speeds will pulse to
near gale-force near Colombia overnight, with the sea heights
building to 12 feet.

ATLANTIC OCEAN...

An upper level trough extends from a cyclonic circulation center
that is about 120 nm to the SSW of Jamaica, through the Windward
Passage, and more northeastward to 32N57W in the Atlantic Ocean.
Precipitation: isolated moderate to locally strong is within 420
nm to the east, and within 300 nm to the west, of the line that
runs from the northern coast of the Dominican Republic near
20N70W to Bermuda.

High pressure in the central Atlantic Ocean will dominate the
region during the next several days. Fresh to occasionally
strong easterly winds will pulse to the north of Hispaniola
during the overnight hours.
