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 1200 UTC surface analysis and satellite imagery through 
1620 UTC.

...TROPICAL WAVES...

An eastern Atlantic tropical wave is along 36W, south of 15N, 
moving westward around 10-15 kt. No significant convection is 
associated with this wave at this time.

A central Atlantic tropical wave is along 46W, south of 15N, 
moving westward at 10-15 kt. No significant convection is 
associated with this wave at this time.

A central Caribbean tropical wave is along 76W, from 19N
southward, moving westward at 10-15 kt. A few showers are noted 
near the wave axis.

...MONSOON TROUGH/ITCZ... 

The monsoon trough enters the Atlantic near 12N16W and continues 
southwestward to 05N23W. Segments of the ITCZ extend from 05N23W 
to 07N34W, 07N38W to 06N45W, and 05N48W to the coast of French
Guiana. No significant convection is noted near the boundaries at
this time. 

GULF OF AMERICA...

Pop-up showers and tstorms are evident in the NE Gulf waters. A
surface trough, a few showers, and locally fresh SE winds are in 
the Bay of Campeche. Ridging associated with subtropical Atlantic 
high pressure prevails across the Gulf, supporting gentle to 
moderate SE winds and 3-5 ft seas. 

For the forecast, fresh to strong E to NE winds will pulse each 
afternoon and evening through the week north of the Yucatan 
Peninsula and in the eastern Bay of Campeche as a diurnal trough 
develops and treks westward across the region. Otherwise, ridging 
over the western Atlantic will maintain moderate S to SE winds and
moderate seas over the central and western Gulf through the 
middle of the week, with gentle to moderate SE winds and slight to
moderate seas in the eastern basin.

CARIBBEAN SEA...

Scattered moderate convection is from the coast of Panama north to
14N and west of 80W, including coastal regions of Nicaragua. Fresh
to strong trades were detected by satellite scatterometer data
across the central and southwest Caribbean and the Gulf of
Honduras. Seas in these winds range from 6-9 ft, with peak seas in
the SW Caribbean off the coast of Colombia. Elsewhere in the
Caribbean Sea, moderate trades and 4-6 ft seas prevail. 

For the forecast, fresh to strong trade winds are expected to 
pulse across the central and west-central Caribbean through the 
middle of the week as a strong pressure gradient prevails between 
high pressure to the north and low pressure in the south-central 
Caribbean. Rough seas in E swell are likely in this region. Fresh 
to strong E to SE winds will also occur each night and morning in 
the Gulf of Honduras, and these winds will expand through much of 
the northwestern Caribbean early in the week after the passage of 
a tropical wave. Elsewhere, rough seas in E swell will occur east 
of the Lesser Antilles and through the passages into the eastern 
Caribbean into today. Otherwise, mainly moderate winds and seas 
are expected across the rest of the basin.

ATLANTIC OCEAN...

The subtropical ridge continues to dominate the tropical Atlantic
waters. Moderate or weaker trades and 4-7 ft seas prevail. 

For the forecast west of 55W, moderate to fresh trade winds will 
pulse south of 25N through the middle of the week as high pressure
prevails over the central Atlantic. At the same time, strong 
winds will be possible just north of Hispaniola. Elsewhere, 
moderate S to SW winds will pulse offshore of Florida into the 
middle of the week as low pressure prevails over the eastern 
United States. Otherwise, mainly gentle to moderate winds and 
moderate seas are expected elsewhere north of 25N through the 
week.
