The monsoon trough passes through the coastal areas of Sierra
Leone near 07N12W to 00N19W. The ITCZ continues from the Equator
to 01S30W to 02S41W at the coast of Brazil. Scattered moderate to
isolated strong convection is 01S to 03S between 31W to 37W.
Scattered showers are possible elsewhere from 08N to the Equator
between 21W to 12W.

GULF OF MEXICO...

Broad upper level westerly wind flow spans the entire Gulf of
Mexico. At the surface, an east-to-west oriented ridge is in the
central Gulf of Mexico. Satellite and observation data indicate
areas of fog reducing visibility to 1-2 miles and isolated spots
to half a mile or less along the NW and northern Gulf extending
southward to Mexico near 22N96W. The fog extends 180 nm SE into
the Gulf. Low ceilings are also observed in some areas near the
coast. Elsewhere in the basin, clear conditions prevail with S
to SE winds around 10 to 15 knots.

High pressure will prevail over the region through Mon night. A
cold front will enter the NW Gulf of Mexico on Tue, then lift N
as a warm front Wed. A strong cold front will enter the NW Gulf
Thu night.

CARIBBEAN SEA...

A surface trough is in the western part of the Dominican
Republic from 20N71W to 15N70W. Showers are possible across
Hispaniola and Jamaica.

High pressure to the north of the area will support fresh to
strong trade winds in much of the central Caribbean Sea through
Thursday night. Gale-force trade winds are expected each night
near the coast of Colombia. Moderate to fresh trade winds will
continue across the remainder of the area.

ATLANTIC OCEAN...

A surface high extends southward from the W Atlantic to the
Bahamas. Further east, a cold front extends southward and enters
the forecast area from 31N52W to 25N56W. Scattered moderate
convection is observed 180 nm east of the boundary. To the south
of the front, surface trough is present from 23N54W to 18N55W.
Scattered showers are possible in the vicinity of the trough axis.
The remainder of the basin to Africa is under a strong 1037 mb
high pressure dominating the region.

High pressure will prevail across the area through Mon. A cold
front entering NW waters Mon will move across the waters N of 27N
through Tue night. High pressure will rebuild over the northern
waters Wed through Thu night.
