...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal areas of Sierra
Leone near 08N13W to 03N15W and the Equator along 20W. The ITCZ
continues from the Equator along 20W, to 02S33W and 03S39W at
the coast of Brazil. Isolated moderate to locally strong
rainshowers are from 04N southward between 13W and 19W, and from
02N southward between 43W and 50W. Rainshowers are possible
elsewhere from 10W eastward, and from 05N southward from 20W
westward.

GULF OF MEXICO...

Broad upper level westerly wind flow spans the entire Gulf of
Mexico.

An east-to-west oriented surface ridge is in the central Gulf of
Mexico.

A stationary front extends from east Texas, toward the border
area with Mexico from 28N to 29N along 100W.

Surface high pressure will cover the area through Monday night.
A cold front will enter the NW Gulf of Mexico on Tuesday, and
then move northward as a warm front on Wednesday. Another cold
front will enter the NW Gulf of Mexico on Thursday night.

CARIBBEAN SEA...

A surface trough is in the western part of the Dominican
Republic, along 71W/72W, from 16N to 20N. Rainshowers are
possible from 16N to 20N between the Mona Passage and Jamaica,
including across Hispaniola.

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...

Surface anticyclonic wind flow covers the area that is between
the stationary front that is to the southeast, and a cold front/
warm front boundary that is to the north, and continuing to the
Bahamas and the Florida east coast.

A stationary front passes through 32N51W to 29N57W to 26N59W,
and to 25N64W. Scattered moderate to strong rainshowers cover
the waters from 30N to 33N between 51W and 54W. Widely scattered
moderate to isolated strong rainshowers are from 26N to 30N
between 51W and 55W. Rainshowers are possible elsewhere from 23N
northward between 50W and 80W.

A surface ridge extends from a 1035 mb high pressure center,
that is near 38N22W, through 35N30W, 32N38W, to 28N45W and
25N55W.

Upper level cyclonic wind flow covers the area that is from 19N
northward between 33W and 41W. An upper level cyclonic
circulation center is near 25N38W.

High pressure will prevail across the area through Monday. A
cold front, entering the NW waters on Monday, will move across
the waters N of 27N through Tuesday night. High pressure will
