Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Sun Apr 19 2026

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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

...SPECIAL FEATURES..
A cold front extends from Louisiana to northern Mexico. Fresh to
near gale force winds, with frequent gusts to gale force within 60
nm of the coast, follow the front over the NW Gulf. Building seas
are in the 4-6 ft range over these waters. The gale force wind
gusts will continue through early this afternoon.

...MONSOON TROUGH/ITCZ...

The monsoon trough is analyzed from 13N17W to 02N20W. The ITCZ
continues from 02N20W to 02S43W. Scattered moderate convection is
noted from 01N to 04N between 16W and 20W. Scattered moderate and
isolated strong convection is noted within 180 nm of the ITCZ
between 30W and 43W.

...GULF OF AMERICA...

A cold front extends from Louisiana to northern Mexico. Associated
winds west of the front are described in the SPECIAL FEATURES
section above. A 1017 mb high is centered over the NE Gulf near
27.5N86.5W. Light to gentle winds, and seas of 1-2 ft, are in the
vicinity of the high center. A surface trough is over the SW Gulf.
The pressure gradient between the high center and this trough is
supporting moderate to fresh winds in the vicinity of the trough,
where seas are in the 4-5 ft range. Elsewhere, gentle to moderate
winds, and seas of 2-4 ft, prevail.

For the forecast, fresh to strong N to NE winds and building seas
will follow the cold front as it moves across the northern Gulf
through the early part of the week. The front will stall from the
Florida Straits to south Texas by late Mon then dissipate into mid
week. Fresh SE winds will return to the northwest Gulf by late
Thu.

...CARIBBEAN SEA...

Gentle to moderate winds prevail across the Caribbean waters,
locally fresh off the coast of Colombia in the south central
Caribbean. Seas are in the 4-5 ft range east of 75W, and 2-4 ft
west of 75W.

For the forecast, a weaker than usual pressure gradient will
support mainly gentle to moderate winds through the forecast
period. Fresh NE winds may develop early this week across the
Windward Passage associated with a late- season cold front moving
into Cuba.

...ATLANTIC OCEAN...

A surface trough extends from the NW Bahamas to western Cuba. High
pressure dominates the remainder of the Atlantic discussion
waters, anchored by a 1023 mb high centered near 32N48W. Light to
gentle winds are noted over the waters N of 28N in the vicinity of
the high center. Gentle to moderate winds prevail over the
remainder of the waters. Seas are in the 4-7 ft range across most
of the discussion waters, except 3-4 ft off the coast of Florida.

For the forecast west of 55W, a cold front will move off the
northeast Florida coast today. Fresh to strong N to NE winds and
rough seas will follow the front as it reaches a position from
Bermuda to Florida Straits by late Mon, and from 31N60W to central
Cuba by late Tue. Winds will diminish through mid week as the
front stalls and dissipates along 22N. High pressure will build
between northeast Florida and Bermuda in the wake of the front.
Large N swell may linger near the dissipating front Wed into Thu.
