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 0000 UTC surface analysis and satellite imagery through 
0500 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 08N13W and extends SW
to 01S30W. The ITCZ continues from 01S30W to 01S46W. Scattered to
locally numerous moderate to strong convection is noted south of 
05N between Africa and Brazil.

...GULF OF AMERICA...

Weak surface ridging extends over the eastern Gulf. Fresh E winds
prevail off the northern coast of the Yucatan Peninsula and into
central portions of the Gulf, with gentle to moderate or weaker 
winds elsewhere. Slight seas prevail across the basin.

For the forecast, a ridge across the Gulf waters, combined with a
coastal trough near Mexico, will support moderate to fresh SE 
winds and moderate seas over the western half of the Gulf, and 
gentle to moderate winds with slight to moderate seas over the 
eastern part of the basin through Thu. In addition, a diurnal 
trough will pulse moderate to fresh winds off the Yucatan 
Peninsula during the evenings through Thu night.

...CARIBBEAN SEA...

A weak pressure gradient is supporting mainly gentle to moderate E
to SE winds over the Caribbean, except for locally moderate winds
over the SE basin and in the eastern Gulf of Honduras. Slight 
seas prevail across the basin. Scattered showers are occurring
over portions of the eastern Caribbean.

For the forecast, a surface trough is located north of the area 
extending from 22N58W to 21N63W to just NE of the Dominican 
Republic near 20N69W. This feature along with a front moving 
across the NW Atlantic will continue to allow a weaker than usual 
pressure gradient across the central and eastern Caribbean Sea 
into Mon, thus resulting in mainly moderate or weaker winds and 
slight to moderate seas, except in the Gulf of Honduras where 
moderate to fresh E to SE winds will pulse due to nearly 
stationary high pressure over the E Gulf of America. Winds are 
forecast to reach moderate to fresh speeds over the east and 
central Caribbean Mon night through Thu as high pressure builds 
again N of the area in the wake of the front. 

...ATLANTIC OCEAN...

A surface trough, remnants of an old frontal boundary, extends 
from 31N49W to 21N55W and then westward along the northern shore 
of Hispaniola and across Cuba. This feature is supporting 
scattered to isolated moderate convection. Fresh to locally 
strong winds in connection to the areas of convection are 
possible. Fresh winds and 8-10 ft seas are also seen on either
side of the trough N of 28N between 40-60W. Fresh to strong N
winds and locally rough seas are also seen E of 20W between 15N
and 25N. The remainder of the Atlantic is seeing moderate to
locally fresh or weaker winds and moderate seas prevail.

For the forecast west of 55W, a surface trough extends from 
22N58W to 21N63W to just NE of the Dominican Republic near 20N69W.
This feature will remain in place through Sun and gradually 
dissipate by Mon. A cold front approaching from the N will 
continue to support moderate to fresh SW to W winds and rough seas
to 9 ft over the NE offshore waters through Sun. Another cold 
front is forecast to enter the waters off NE Florida by Sun night,
extend from near Bermuda to South Florida by Mon night, and from 
31N60W to the NW Bahamas by Tue night before dissipating. Moderate
to fresh northerly winds and moderate seas are expected in the 
wake of the front N of 27N.
