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
2200 UTC.

...TROPICAL WAVES...

A tropical wave axis is near 36W south of 20W, moving west around
10-15 kt. Scattered moderate convection in the vicinity of the
wave axis.

A tropical wave axis is near 52W south of 20N, moving west at 15
kt. Scattered moderate convection is noted from 08N to 12N
between 51W and 55W.

A tropical wave axis is near 68W south of 20N, moving west at 15
kt. Scattered moderate isolated strong convection is noted from
12N to 18N between 64W and 71W.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 13N16W to 14N28W to 11N41W to
10N49W. The ITCZ continues west of the tropical wave, from 10N55W
to 09N61W. Scattered moderate isolated strong convection is noted
from 08N to 13N E of 20W to the coast of Africa. This is ahead of
the next tropical wave which will move off the coast of Africa
tonight. Scattered moderate convection is noted within 210 nm S of
the monsoon trough between 40W and 44W. Scattered moderate
convection is noted within 90 nm of the ITCZ.

GULF OF MEXICO...

High pressure of 1020 mb is centered over the eastern Gulf near
27N85W. A surface trough extends across the SW Gulf. Gentle to
moderate winds prevail over the SW Gulf in the vicinity of the
trough. Light to gentle winds prevail over the remainder of the
Gulf waters.

Light to gentle winds will dominate the Gulf waters through Wed
night. Stronger winds are expected in the eastern Bay of Campeche
and the Yucatan peninsula adjacent waters at night due to local
effects.

CARIBBEAN SEA...

A tropical wave is moving across the central Caribbean. Active
convection is noted east of the tropical wave, including much of
the eastern Caribbean. Fresh to strong winds prevail over the
central Caribbean. Moderate to fresh winds prevail over the
eastern Caribbean. Gentle to moderate winds prevail over the
western Caribbean.

Fresh to strong trade winds are expected across the central and
southwest Caribbean through Wed. Winds will increase to near gale
force over Colombia adjacent waters and the Gulf of Venezuela Sat
night and Sun as a tropical wave moves across the region. Moderate
to fresh winds are expected elsewhere.

ATLANTIC OCEAN...

A weak surface trough is analyzed from 28N64W to 27N69W to 29N75W,
with 1017 mb low pressure along the trough near 27N72W. Farther
east, a 1022 mb high pressure is centered near 27N56W. Moderate to
fresh tradewind flow is noted south of 20N, with light to gentle
winds north of 20N.

Light to gentle variable winds are expected across the northern
waters through Wed. Otherwise, moderate to fresh easterly winds
will dominate the waters south of 23N from the Great Bahama Bank
to north of Hispaniola.
