...MONSOON TROUGH/ITCZ...

The monsoon trough passes from the coastal areas of Liberia near
05N10W to 00N15W. The ITCZ continues from this point to 02S20W to
the coast of Brazil near 03S41W. Scattered moderate to isolated
strong convection is along the monsoon trough from 01N-06N
between 10W-15W. Isolated moderate convection is along the ITCZ
from 02S-07S between 25W-35W.

GULF OF MEXICO...

A 1025 mb high is centered over the W Atlantic near 30N66W
producing 10-20 kt SE flow over the Gulf of Mexico. A cold front
is inland over central Texas moving toward the Gulf. In the upper
levels, zonal flow prevails with moisture over the N Gulf N of 26N
and strong subsidence S of 26N.

High pressure will linger over the forecast waters through Sat. A
cold front will enter the NW Gulf of Mexico on Sun, stall along
the northern coast Mon and Tue, then lift N as a warm front Wed.
Strong SE to S winds are possible in the Gulf Tue night through
Thu night.

CARIBBEAN SEA...

A surface trough is over the central Caribbean from 20N70W to
14N72W. Scattered showers are over Puerto Rico and Hispaniola from
16N-20N between 66W-74W, moving W with the trades. Elsewhere,
scattered showers are over the SW Caribbean, Panama, and Costa
Rica S of 11N. In the upper levels, a ridge is over the W
Caribbean with axis along 85W, while a trough is over the E
Caribbean with axis along 64W. Strong subsidence covers the entire
Caribbean and Central America.

High pressure north of the area will support fresh to strong
trades over much of the central Caribbean through Thu night, with
gale force trades expected each night near the coast of Colombia.
Moderate to fresh trades will continue across the remainder of the
area through early next week.
