Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Tue Mar 25 2025

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 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...

Caribbean Gale Warning: Strong to gale force winds are pulsing off
the coast of Colombia, with seas peaking near 13 ft. Winds and
seas will decrease this morning, then pulse to gale force
offshore of Colombia again tonight. Winds will then pulse to near
gale force at night through Fri.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 09N13W and continues
SW to 06N19W. The ITCZ continues from 06N19W to 00N50W. Scattered
moderate convection is noted from 00N to 04N between 23W and 47W.

...GULF OF MEXICO...

A surface trough extends across the W Gulf, with weak high
pressure over the NE Gulf. The pressure gradient between these
features is supporting moderate to fresh winds, and seas of 4-5
ft, N and W of the Yucatan peninsula. Light to gentle winds, and
seas of 2-4 ft prevail elsewhere.

For the forecast, high pressure across the basin will generally
support light to gentle SE to S winds over the western and central
Gulf, and gentle to moderate winds over the eastern part of the
basin into Wed. A surface trough will develop over the Yucatan
Peninsula and move into the Bay of Campeche nightly through early
this week, supporting pulses of fresh to locally strong winds over
adjacent waters. A cold front will skirt the NE Gulf early today.
High pressure building into the basin in its wake will lead to
moderate to fresh southeast winds and building seas across the NW
Gulf by Thu.

...CARIBBEAN SEA...

A Gale Warning is in effect offshore Colombia. Please, refer to
the Special Features section above for more information.

Aside from the area of gale force winds, fresh to strong winds
prevail over the central Caribbean, with seas in the 8-11 ft
range. Fresh winds, and seas of 7-9 ft, are over the eastern
Caribbean. Fresh to strong winds, and seas of 6-7 ft, are found in
the Gulf of Honduras. Gentle to moderate winds, and seas of 4-6
ft, prevail elsewhere over the western Caribbean.

For the forecast, fresh to strong E to NE winds offshore of
Colombia and Venezuela will pulse to gale force offshore of
Colombia tonight. These winds will then pulse to near gale force
at night through Fri. Fresh to strong winds in the Gulf of
Honduras will diminish today.

...ATLANTIC OCEAN...

High pressure dominates the Atlantic discussion waters. Fresh to
strong winds prevail over the far eastern Atlantic waters west of
Africa to near 25W, where seas are in the 8-11 ft range. Moderate
to fresh winds, and seas of 4-7 ft are elsewhere N of 20N. Fresh
to locally strong winds, and seas of 7-8 ft, prevail S of 20N.

For the forecast west of 55W, high pressure over the western
Atlantic will support gentle breezes and slight to moderate seas
north of 22N through Wed. The area of high pressure will shift
eastward enabling a weak cold front to move off the northeast
Florida coast early today before dissipating. Fresh to locally
strong winds are likely to pulse off the northern coast of
Hispaniola into Wed. Another cold front may move into waters
between northeast Florida and Bermuda Wed. High pressure will
build in the wake of the front, bringing an increase in winds
across much of the waters S of 28N by the end of the week.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1215 UTC Wed Mar 26 2025

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 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...

Caribbean Gale Warning:
The pressure gradient between a surface ridge N of the area and
the Colombian low is supporting strong to gale force winds off
Colombia. Seas with these winds are peaking near 11 ft. Winds will
diminish below gale force early this morning.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 07N12W and extends
southwestward to 05N16W. The ITCZ continues from 05N16W to
00N48W. Scattered moderate convection is noted from 00N to 05N
between 08W and 40W.

...GULF OF MEXICO...

High pressure dominates the northern Gulf, anchored by a 1022 mb
high centered just S of the Florida panhandle. A surface trough
extends off the west coast of the Yucatan peninsula. The pressure
gradient between these features is supporting fresh winds off the
west coast of the Yucatan, where seas are in the 3-4 ft range.
Light winds, and seas of 2 ft or less are in the vicinity of the
high center. Gentle to moderate winds, and seas of 2-4 ft prevail elsewhere.

For the forecast, the aforementioned area of high pressure will
support gentle to moderate winds over much of the basin today.
Winds will increase to moderate to fresh across the NW Gulf Thu,
then further increase to fresh to strong Thu night into Fri while
expanding in coverage before beginning to diminish Fri night. Seas
generated by these winds will build to around 10 ft in the NW
Gulf Fri and Fri night. A weak cold front may move into the NW
Gulf late Sun night into early next week.

...CARIBBEAN SEA...

Please refer to the Special Features section for details on a
Gale Warning off the coast of Colombia.

Aside from the area of gale force winds, fresh to near gale winds
are over the south central Caribbean, where seas are in the 8-10
ft range. Moderate to fresh winds, and seas of 6-8 ft prevail
elsewhere E of 80W. Over the western Caribbean, gentle to moderate
winds, and seas of 4-7 ft, are noted.

For the forecast, gale force winds off Colombia will diminish this
morning. Winds off Colombia will then pulse to near gale force
speeds tonight through Fri and to fresh to strong speeds for the
remainder of the period. Fresh to strong winds will develop in
the lee of Cuba, in the Windward Passage, over the waters between
Cuba and Jamaica and south of Hispaniola from late Thu through this weekend.

...ATLANTIC OCEAN...

High pressure dominates much of the Atlantic discussion waters,
anchored by a 1038 mb high centered near 38N39W. Fresh to strong
winds, and seas of 6-9 ft prevail over the waters E of 60W. Gentle
to moderate winds, and seas of 3-6 ft, are found over the waters W of 60W.

For the forecast west of 55W, a cold front will enter the waters
between northeast Florida and Bermuda today, and will shift
eastward, moving east of 55W by Thu night. High pressure will
build in the wake of the front, bringing an increase in winds
across much of the waters S of 28N by the end of the week. Winds
and seas will start to decrease this weekend as the high shifts
eastward and weakens.
