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 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through 
1130 UTC.

...ITCZ/MONSOON TROUGH...

The Monsoon Trough extends from the African coast near 06N10W to 
04N14W where it transitions into the ITCZ and continues to 
00N48W. Scattered moderate convection is observed within 90 nm 
either side of the ITCZ between 19W-40W.

...DISCUSSION...

GULF OF MEXICO...

A cold front extends across the northwest Gulf from 29N92W to
26N96W. No significant convection is observed along this boundary
at this time. A 1012 mb high is centered across the northeast 
waters near 27N87W. Scatterometer data depicts light to gentle 
anticyclonic flow prevailing across most of the basin except north
of the cold front over the northwest waters, where moderate to 
fresh northerly winds prevail. Expect for the front to continue 
moving east with fresh to strong northeasterly winds developing 
behind it. The front will extend from the Florida panhandle to 
the northern Bay of Campeche by late this morning and pass 
through the Straits of Florida on Sunday with southeast return 
flow developing over the Gulf mainly west of 90W.

CARIBBEAN SEA...

A broad area of high pressure extends across the central and
eastern Atlantic reaching the Caribbean waters. Winds are 
generally light and variable across most of the basin with wave 
heights around 2 to 3 FT. Moderate easterly winds are depicted in
scatterometer data south of 13N between 72W-78W. As high pressure
builds to the north of the area by late in the weekend, moderate 
to fresh trade winds are expected to resume. Strongest winds are 
expected once again within 90 NM of the coast of Colombia by late 
Sunday.
  
...HISPANIOLA...

A surface trough extends across the northwestern portion of the
island with cloudiness and isolated showers. The trough will 
dissipate within the next 24 hours. Low-level southwesterly flow 
will prevail enhancing afternoon showers and thunderstorms through
the weekend.

ATLANTIC OCEAN...

A 1007 mb surface low is centered near 30N74W. This low will
continue moving northeast at about 15 kt while occluding. A cold 
front extends from 31N65W to 25N66W with isolated showers mainly
north of 27N. Fresh to strong southeasterly winds prevail in the 
vicinity of the low and front mainly north of 28N between 63W-69W.
To the east, a stationary front was analyzed from 31N38W to 
22N56W. The remainder of the basin is under the influence of a 
surface ridge extending southwest from a 1026 MB high centered 
near 33N26W. Expect during the next 24 hours for the cold front to
continue moving east with convection. The stationary front will 
dissipate.
