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 1800 UTC surface analysis and satellite imagery through
2230 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is along 58W south of 16N, moving W 
at 10 kt. TPW imagery shows enhanced moisture east of the wave, 
and scattered showers are noted S of 10N within 300 nm east of 
the wave axis. 

The axis of a tropical wave is along 84W south of 20N, moving W 
at 10-15 kt. Scattered moderate to strong convection associated
with this wave is noted over Honduras, Nicaragua, and Costa Rica. 

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Guinea near 10N14W 
to 06N23W. The ITCZ extends from 06N23W to 01N40W. Scattered 
moderate convection is occurring along the monsoon trough from 
05N to 08N between 17W and 21W.

GULF OF MEXICO...

A cold front is analyzed over the NW Gulf from south-central 
Louisiana to just south of the Texas/Mexico border. GOES-16 
satellite imagery and lightning data show a line of strong
thunderstorms ahead of the front, moving across the central Gulf
approaching 90W. These storms are likely producing gusty winds
and locally rough seas. An elongated surface trough extends over
the NE Gulf and across central Florida, supported by an upper- 
level trough over the eastern Gulf. Another line of thunderstorms
is noted roughly from 26N83W to 23N86W. Outside of convection, 
winds are generally light to moderate based on earlier 
scatterometer data. A 1730 UTC altimeter pass over the eastern 
Gulf shows 2-4 ft seas, which is consistent with nearby buoy 
observations.

Weak low pressure over the Florida Peninsula, with an associated 
trough extending into the northeast Gulf, will lift north and
move inland Wed. A cold front offshore the Texas coast will 
weaken into a trough, then stall over the NW Gulf into Thu. Smoke
and haze from fires over southern Mexico will reduce visibility 
at times over the SW Gulf. A weak pressure pattern will prevail 
for the end of the week into the weekend. 

CARIBBEAN SEA... 

Moderate to fresh trades prevail over the central Caribbean per
earlier scatterometer data. ELsewhere, gentle to moderate winds
are noted over the rest of the basin. Isolated convection is 
noted over eastern Cuba, Hispaniola, and Puerto Rico, but no 
significant convection is occurring over the offshore waters this
evening. Seas remain 4-7 ft, with the highest wave heights 
associated with the fresh trades in the south-central waters. 

Fresh to strong trades will persist in the south-central 
Caribbean through tonight, then remain fresh into the weekend. 
Fresh winds will pulse at night over the Gulf of Honduras through
Wed night. During periods of lesser winds, smoke from fires in 
Central America may restrict visibility in the Gulf of Honduras. 
A tropical wave along 84W will move into Central America tonight.

ATLANTIC OCEAN...

A large area of fresh to locally strong winds N of 26N W of 77W 
is associated with low pressure near the east-central coast of
Florida, and its associated trough that extends eastward to 
29N77W. Scattered moderate to strong convection continues along 
the trough, and from South Florida eastward to the NW Bahamas.
Some tropical development of this system is possible through 
early Wed if it remains offshore while moving slowly northward 
near the NE Florida and Georgia coasts. There is a low chance of
formation through 48 hours associated with this system.

Elsewhere, another western Atlantic trough extends from 27N63W to
20N70W, with isolated moderate convection occurring east of the
trough axis. In the central Atlantic, fresh winds are noted in
earlier scatterometer data north of a trough extending from
29N39W to 24N51W. Moderate to locally fresh trades prevail over
the central Atlantic south of 15N. Yet another trough lingers off
the coast of Africa from 31N25W to 22N17W, but no significant
convection is associated with it. 

A 1010 mb low pressure inland of Daytona Beach, Florida will 
move north and northeast tonight into Wednesday along the the 
coast of Florida and Georgia, before moving north of the area. 
Atlantic waters to the north and east of this low will have winds
of 20 to 30 kt along with numerous showers and thunderstorms. A 
weak surface trough along 68W will dissipate Wed.
