Tropical Weather Discussion for North America, Central America
Gulf of America, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
2230 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 14N17W to 11N20W. The
ITCZ continues from that point to 09N60W. Scattered moderate
convection prevails from 03N-10N and E of 34W.

...GULF OF AMERICA...

A surface trough is causing scattered showers at the Yucatan
Channel, including part of the Florida Straits. Otherwise, a
broad surface ridge continues to dominate much of the Gulf.
Moderate to fresh E winds and moderate seas are present across
the Florida Straits. Light to gentle winds and slight seas are
found at the northeastern Gulf. Gentle to moderate E to SE winds
and slight to moderate seas dominate the rest of the Gulf.

For the forecast, moderate to locally fresh E to SE winds and
slight to moderate seas will occur over the basin through Fri
morning as high pressure prevails over the northeastern Gulf and
southeastern U.S. Elsewhere, moderate to locally fresh NE winds
will pulse offshore of the Yucatan Peninsula and into the eastern
Bay of Campeche each afternoon and evening through this weekend.
Fresh to strong SE winds may develop over the northwestern Gulf
late this weekend as low pressure strengthens in the south-
central U.S.

...CARIBBEAN SEA...

A surface trough is producing scattered moderate convection over
the eastern Caribbean, including the Mona Passage and Lesser
Antilles. The eastern extension of the East Pacific monsoon trough
is triggering scattered showers and thunderstorms along the
Caribbean coast of Panama mainly S of 10N. Moderate to fresh NE
to E trade winds and rough seas are evident at the south-central
basin. Gentle to moderate NE to E trade winds with moderate seas
prevail elsewhere.

For the forecast, moderate to occasionally fresh E to NE winds
are expected over the Caribbean through this weekend as a moderate
pressure gradient prevails between high pressure to the north and
low pressure in the south-central basin. Locally strong winds and
rough seas will pulse offshore of Colombia tonight, and again by
this weekend.

...ATLANTIC OCEAN...

A stationary front meanders west-southwestward from the north-
central Atlantic across 31N56W to the northern Bahamas. A surface
trough is analyzed from 31N52W to 25N61W. Scattered moderate to
strong convection is found near the front/trough north of 21N
between 50W and 65W. This activity is also supported by an upper-
level low in the area. Another stationary front curves
southwestward from the northeastern Atlantic across 30N35W to
24N42W. Scattered showers are present up to 60 nm along either
side of this boundary. Another surface trough is triggering
scattered moderate convection from 20N to 22N between 66W-71W.

Light to gentle winds and moderate seas are noted north of 25N
between 65W and the Florida/Bahamas. Elsewhere, gentle to
moderate NE to E winds and moderate seas prevail.

For the forecast west of 55W, moderate to occasionally fresh NE
winds are expected north of Hispaniola and Cuba and through the
Bahamas through Fri as high pressure prevails over the
northeastern Gulf of America and the southeastern U.S. Elsewhere,
moderate to fresh NE winds are expected north of 27N and east of
65W through Thu as a complex low pressure system forms. Moderate
or weaker winds and slight to moderate seas are expected elsewhere
through Fri. Increasing SW winds and building seas may occur
offshore of northern Florida this weekend ahead of a cold front
moving through the southeastern U.S.
