Tropical Weather Discussion for North America, Central America
Gulf of Mexico, 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 1800 UTC surface analysis and satellite imagery through 
2350 UTC.

...TROPICAL WAVES...

A tropical wave is along 36W, from 05N to 20N, moving westward 
at 5-10 knots. A 1011 mb low pressure center is along the tropical
wave near 14.6N. Scattered showers are from 13N to 17N between 34W
and 40W. 

A tropical wave is along 56W, from 04N to 20N, moving westward at
5-10 knots. Scattered moderate convection is in the region of the
monsoon trough from 04N to 10N between 50W and 60W. 

A tropical wave is along 84W, south of 20N, moving westward at 5-10
knots. Scattered moderate convection is inland Central America and
in the Nicaragua offshore waters. 

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 15N17W to 14N36W to 09N51W to
08N60W. Numerous moderate isolated strong convection is from 06N
to 13N between 20W and 26W. Scattered moderate convection is
elsewhere from 02N to 11N between 0W and 17W, and from 05N to 13N
between 43W and 61W.  

GULF OF MEXICO...



For the forecast, relatively weak high pressure will remain over 
the area through the forecast period maintaining gentle to 
moderate winds and slight seas. Moderate to fresh NE to E winds 
will pulse near and to the W of the Yucatan peninsula due to local
effects during the late afternoons and at night through Thu. 

CARIBBEAN SEA...



For the forecast, surface ridging north of the area will continue
to support moderate to fresh trade winds in the eastern and 
central Caribbean through the forecast period, while gentle to 
moderate winds will continue across the western Caribbean. 

ATLANTIC OCEAN...

The Bermuda-Azores High is the main feature across the Atlantic
subtropical waters, which is supporting generally gentle to
moderate E to SE winds in the central and western Atlantic with 
slight to moderate seas. A surface trough weaken the ridge in the
SW N Atlantic waters extending from 19N to 27N along 68W. The
trough is generating heavy showers and tstms from 23N to 30N
between 63W and 69W. Over the far eastern subtropical Atlantic, a
tighter pressure gradient continues to support fresh to strong NE
winds and seas to 8 ft between the Canary Islands and NW Africa. 

For the forecast W of 55W, the surface trough will move westward
toward the Bahamas through late Wed accompanied by scattered to 
numerous showers and thunderstorms. Winds and seas may be higher 
in and near scattered showers and thunderstorms. High pressure 
will build in the wake of the trough allowing for generally a 
gentle to moderate E to SE flow beginning on Wed.
