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 0000 UTC surface analysis and satellite imagery through
0545 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from Africa near 04N05W to 00N16W. The
ITCZ continues from 00N16W to the coast of Brazil near 04S36W.
Numerous moderate to scattered strong convection is seen along the
monsoon trough and the ITCZ from the coast of Liberia west to 29W
and north of 02S-06N

GULF OF MEXICO...

A stationary front enters the Gulf from 26N82W to 23N90W and
continue into the Bay of Campeche to near Ciudad Del Carmen,
Mexico. There is also a trough in the eastern Gulf that extends
from across the Yucatan Peninsula. Additionally, a trough extends
from the stationary front in the Bay of Campeche to the mouth of
the Rio Grande, from 21N95W to 25N97W. Showers and embedded
thunderstorms are seen along and south of the stationary front in
the eastern Gulf just off the southwest Florida coast. There are
also light showers and clouds moving across the western and
northern Gulf. Scatterometer data shows winds between light and
gentle out of the north-northeast as high pressure builds into the
region. In the western Gulf, winds are moderate to fresh out of
the east.

A stationary front from 23N90W to the Bay of Campeche will begin
to dissipate by Thu. High pres building in the wake of the front
will prevail through Sun night.

CARIBBEAN SEA...

A subtropical jet stream stretches from the eastern Pacific Ocean
east-northeast to the north-central Caribbean and to the northeast
Caribbean. To the south of this jet stream branch, moist atmosphere
is present at the mid and upper-levels of the atmosphere. Scattered
to broken low-level clouds are moving quickly westward in the trade
wind flow. Some of these may contain isolated showers, with the
exception of the area from 16N to 18N and between 63W and 76W,
where a large patch of low clouds with scattered showers and
isolated weak thunderstorms is noted. Gentle to moderate trades
are seen across the eastern and central Caribbean. Light to gentle
trades are seen in the northwest Caribbean. Moderate to fresh
winds are seen from 13N73W N of Colombia.

High pres N of the area will support fresh to strong NE to E
winds across the S central Caribbean through Sun night, pulsing to
near gale force at night. Otherwise, mainly moderate to fresh
trade winds will prevail across the Caribbean and tropical
Atlantic W of 55W through Sun night. Fresh easterly swell will
build in the tropical Atlantic by the end of the week.

ATLANTIC OCEAN...

The cold front enters the waters at 31N72W and extends
southwestward into FLorida near 27N80W. Showers and thunderstorms
are seen along and ahead of the front west of 73W. A pre-frontal
trough is seen 80 nm southeast of the front extending from 30N73W
across the northwest Bahamas and south of the Florida Keys near
24N80W. A cluster of thunderstorms are also moving southward
across the northern islands of the Bahamas associated with the
trough. Elsewhere, a trough stretches from 32N51W to 27N56W.
Scattered showers are seen in the vicinity of the trough axis
ahead of a stationary front north of the area. Further south
closer to the Puerto Rico, a surface trough is also present from
24N64W to 19N67W. A few showers are noted in the vicinity of the
trough.

The front will stall from near 30N65W to S Florida Wed night.
High pressure will build in the wake of the front and prevail
across the area through Sun night.
