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
1015 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coast of Sierra Leone near
07N12W to 02N22W. The ITCZ continues from 02N22W to 02S43W.
Scattered showers are noted within 90 nm north of the ITCZ mainly
west of 32W.

GULF OF MEXICO...

Mid-to upper-level ridging prevails over the Gulf of Mexico,
leading to mostly fair weather across the basin. Patchy fog is
reported in the NW Gulf. Gentle to moderate anticyclonic winds
prevail across the basin except over the Florida Straits, where
moderate to fresh easterly winds are noted. Seas across the basin
range between are 3 to 6 ft.

Low pressure over northern Mexico and a surface ridge across
the northern Gulf will support fresh SE winds this morning. A
slow-moving cold front will reach the NW Gulf tonight, then stall
and weaken over the northern Gulf through the weekend. Strong NE
to E winds will develop each evening north of the Yucatan
Peninsula, and weaken overnight as a thermal trough moves
offshore.

CARIBBEAN SEA...

Mid-level troughing extends across the northern Caribbean.
Scattered showers are noted across Hispaniola, Puerto Rico and
the Lesser Antilles. Fresh to strong easterly winds are noted
south of Hispaniola across the central Caribbean, while strong
winds are also noted in the Windward Passage. Moderate to fresh
trades prevail across the remainder of the basin. Seas are ranging
between 3 to 7 ft.

A ridge north of the area will support fresh to strong winds in
the south-central Caribbean through Mon night. Strongest winds
will be near the coast of Colombia each night. Fresh to strong
winds will persist over the Windward Passage and south of
Hispaniola through Sun.

ATLANTIC OCEAN...

Surface ridge prevails across the west Atlantic mainly west of
55W. A slow moving cold front extends across the central Atlantic
from 31N42W to 23N48W. A surface trough extends south of the
front from 21N49W to 11N55W. Showers are moving along and within
75 nm east of the front, with seas of 9-12 ft. Another surface
trough is analyzed west of the cold front from 31N44W to 28N46W
with no significant weather associated with it. Surface ridging
extends across the eastern Atlantic.

Strengthening high pressure over the west-central Atlantic will
increase winds and seas mainly S of 25N through tonight. A weak
cold front drifting SE from the coast of Georgia this weekend will
stall east of northern Florida Mon night, then lift north as a
warm front on Tue. The low/front over the central Atlantic will
push south through the next 24 hours enhancing winds and seas
north of 27N between 40W-48W.
