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
1115 UTC.

...TROPICAL WAVES...

A tropical wave extends its axis along 28W from 02N-13N, moving W
at 10 kt. This wave is noted in model guidance at 700 mb. SSMI
TPW imagery shows high moisture content associated with it.
Widely scattered moderate convection is from 01N-10N between
24W-30W.

A tropical wave extends its axis along 48W from 03N-13N, moving W
at 15 kt. This wave is also noted in model guidance at 700 mb,
and SSMI TPW imagery shows high moisture content associated with
it. Scattered showers are noted within 120 nm of the wave's axis.

A tropical wave extends its axis along 65W from 05N-13N, moving
W at 10-15 kts. This wave is noted in model guidance at 70TThe
stationary front will dissipate this weekend.he stationary front
will dissipate this weekend.0 mb. SSMI TPW imagery depicts
moderate to high moisture content near and east of the wave axis.
Scattered showers are noted within 180 nm of the wave axis.

...MONSOON TROUGH/ITCZ...

The monsoon trough is analyzed from 10N14W to 06N27W. The ITCZ
extends from 05N30W to 06N47W, and continues W of a tropical wave
near 07N50W to 07N58W. Aside from the showers and convection
related to the tropical waves, widely scattered moderate
convection is from 00N-07N between 14W-24W, and from 08N-11N
between 36W-44W.

GULF OF MEXICO...

As of 0900 UTC, a cold front extends from S Florida near 27N80W
to the NE Yucatan Peninsula near 21N87W. Scattered showers are
within 120 nm of the front. A 1018 mb high is centered over the NW
Gulf of Mexico near 29N91W.

The front will gradually dissipate on today as an easterly return
flow develops across the basin.

CARIBBEAN SEA...

A tropical wave is over the W Caribbean. See above. A broad area
of high pressure centered over the west Atlantic extends across
most of the basin. 10-20 kt tradewinds are over the remainder of
the Caribbean Sea. Widely scattered moderate convection has also
advected over the Leeward Islands, Puerto Rico, and E Hispaniola.
Elsewhere, isolated moderate convection is over the SW Caribbean
south of 13N between 75W-84W. This convection is due to the
eastern extent of the Eastern Pacific monsoon trough.

The western Atlantic surface high will continue to shift eastward
through the weekend and produce fresh tradewinds east of 80W,
especially the south-central Caribbean through this evening.
These winds will be strongest at night close to the coast of
Colombia. A Gulf of Mexico cold front will stall and weaken near
the Yucatan Channel today. Trades will diminish by Sunday.

ATLANTIC OCEAN...

A cold front is over the W Atlantic from 31N78W to S Florida near
27N80W. Isolated moderate convection is within 120 nm of the
front. A western Atlantic 1031 mb high is centered near 36N49W. A
stationary front enters the central Atlantic near 32N36W and
extends to 21N46W to 19N62W. Widely scattered moderate convection
is within 120 nm of the front S of 27N. An eastern Atlantic 1031
mb high is centered near 36N19W.

The cold front will weaken and stall from near 31N74W to southern
Florida this evening then gradually shift northward on Sunday.
The stationary front will dissipate this weekend.
