1215 UTC Wed Mar 12 2025

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 
1000 UTC.

...SPECIAL FEATURES...

W Atlantic Gale Warning: A cold front enters the SW North Atlantic
waters, extending from a 996 mb low centered just N of Bermuda 
through 31N61W to the east coast of Cuba. Scattered moderate 
isolated strong convection and strong to gale-force SW winds are 
occurring within 150 nm east of the front north of 24N. Recent 
satellite scatterometer data captured fresh to gale-force 
southerly winds ahead of the front to near 50W and north of 21N. 
Strong to near gale-force NW to W winds are occurring behind the 
front to 74W and north of 23N. Large NW to W swell behind the 
front is producing a significant area of seas 12 ft and greater N 
of 25N between the front and 75W early this morning that will 
shift eastward through Thu. The front is expected to reach from 
31N55W to the NE Dominican Republic by Wed evening, and from 
23N55W to eastern Dominican Republic by Thu evening. SW gales 
ahead of the front will continue through Wed evening before 
lifting N of 31N. Winds and seas will diminish from west to east 
through late week as high pressure builds over the western 
Atlantic in the wake of the front.

details.

...MONSOON TROUGH/ITCZ... 

A monsoon trough enters the Atlantic through the coast of Guinea near
10.5N14.5W and continues southwestward to 00.5N20W. The ITCZ 
extends from 00.5N20W to 00N41W to the coast of Brazil near 01S47W.
Scattered moderate convection is observed south of 04.5N and 
between 10W and 51W. 

...GULF OF AMERICA...

1020 mb high pressure centered over the east central Gulf dominates
the basin, and is maintaining fairly tranquil weather conditions.
Moderate southerly winds and seas prevail west of 93W. Moderate 
to locally fresh easterly winds and slight seas are found off 
western Yucatan. Elsewhere, moderate or weaker winds and slight 
seas are prevalent.

For the forecast, high pressure centered over the E central
Gulf will slide eastward across Florida and into the W Atlantic
Thu. Moderate to fresh southerly return flow will set up over
the western Gulf today, then weaken Thu as a front approaches SE
Texas. Southerly winds will then increase to fresh to strong
speeds across most of the basin Fri, then to strong Fri night
ahead of a cold front. The cold front will move into the NW Gulf
early Sat, and quickly weaken, reaching from the Florida
Panhandle to just S of Veracruz, Mexico by Sun morning. 

...CARIBBEAN SEA...

A stationary front extends from the E coast of Cuba to the Bay
Islands and northern Honduras. Widely scattered shallow showers 
are occurring near this boundary. High pressure over the central 
Atlantic supports fresh to strong easterly trade winds across the 
south- central Caribbean waters S of 13N, along with seas of 4-6 
ft. Moderate to locally fresh E winds are noted in the SE 
Caribbean and in the lee of Cuba. Seas in these waters are slight
to moderate. Elsewhere, light to gentle winds and slight to 
moderate seas prevail.

For the forecast, the aforementioned front will gradually become 
W to E aligned from central Hispaniola to northern Belize by Wed 
night before dissipating. Moderate to fresh N to NE winds and 
moderate seas will prevail N of the front through this morning. 
Otherwise, weak high pressure N of the area will support moderate 
to fresh NE to E trade winds offshore of northwestern Colombia and
in the Gulf of Venezuela most of the week. Winds there will pulse
to fresh to strong speeds at night during the upcoming weekend. 
Fresh to strong SE to S winds will develop across the Gulf of 
Honduras and NW Caribbean Fri night becoming strong on Sat as 
strong high pressure builds across the western Atlantic. 

...ATLANTIC OCEAN...

Please read the Special Features section about an ongoing Gale 
Warning in the SW North Atlantic.

The SW North Atlantic west of 55W is dominated by a strong cold 
front moving across the waters, with the impacts associated with 
this boundary described above in the Special Features section. 
Farther east, a cold front enters the basin near 31N19W to 
26N30W, becoming a stationary front to 24N51W. Isolated showers 
are noted near this boundary. Fresh to strong W-NW winds are 
present north of 29N and between 24W and 38W, along with rough 
seas to 12 ft in NW swell. The remainder of the tropical Atlantic
is under the influence of a broad subtropical ridge that sustains 
moderate to fresh NE to E winds south of 20N. Seas in this area 
are 6-9 ft, with the highest seas occurring between the Cabo 
Verde Islands and the African mainland. Elsewhere, moderate or 
weaker winds and moderate to locally rough seas are prevalent.

For the forecast west of 55W, the W Atlantic cold front is 
expected to reach from 31N55W to the NE Dominican Republic by Wed 
evening, and from 23N55W to eastern Dominican Republic by Thu 
evening. The southern portion of the front will then become 
stationary across the coastal waters of Puerto Rico by Fri morning
then dissipate. SW gales ahead of the front will persist through 
Wed evening before lifting N of 31N. Large NW to W swell behind 
the front is producing a significant area of seas 12 ft and 
greater N of 25N between the front and 75W early this morning that
will shift eastward through Thu. Winds and seas will diminish 
from west to east through Fri as high pressure builds over the 
western Atlantic in the wake of the front. Looking ahead, strong
high pressure will settle across the N central Atlantic Fri night
through the upcoming weekend, producing increasing easterly winds
and building seas.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough enters the Pacific near 07N77W and extends to
01N85W. The ITCZ continues from 01N85W to beyond 02N140W.
Scattered moderate convection is occurring south of 02N between
87W and 105W. 

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

See the Special Features Section for details on the Significant 
Swell event impacting the waters offshore of Baja California.

Moderate to locally fresh N winds are occurring south of 25N and
east of 115W, including near Cabo San Lucas, as a moderate 
pressure gradient prevails between a weakening cold front in 
northwestern Mexico and a 1017 mb high centered near 21N123W.
Farther north, a 1012 mb low centered near 33N119W is supporting
moderate to locally fresh W to SW winds offshore of Baja 
California Norte and in northern portions of the Gulf of 
California. Residual rough seas of 8 to 11 ft in N to NW swell 
cover most areas offshore of Baja California. Otherwise, gentle 
to moderate winds and seas of 3 to 6 ft prevail offshore of 
southwestern Mexico. 

For the forecast, rough seas of 8 to 11 ft will propagate 
southeastward through the waters offshore of Baja California 
today. A cold front will push into the Baja California Norte 
waters early on Thu, producing fresh SW winds ahead of the front,
and fresh to locally strong NW winds behind the front through 
late Thu morning. Fresh to strong SW winds are expected in the 
northern Gulf of California this evening ahead of the front, with
strong to near-gale force W to NW winds in the wake of the front
Thu into early Fri. N swell associated with the cold front will 
reinforce rough seas offshore of Baja California Norte by Thu 
afternoon, with rough seas spreading through all waters offshore 
of the peninsula through Fri. Peak seas of 12 to 14 ft are 
anticipated north of 27N and west of 117W Thu evening through 
Fri. Elsewhere, pulsing moderate to locally fresh N to NW winds 
will prevail offshore of western Mexico through Fri, before more 
widespread fresh to locally strong winds develop Fri afternoon as
the aforementioned cold front moves southeastward through the 
region. Looking ahead, gale force winds will be possible in the 
Gulf of Tehuantepec Sun night through early next week. 

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...

Fresh to locally strong NE to E winds and seas of 4 to 6 ft are 
noted in the Gulf of Papagayo, with moderate to locally fresh NE 
winds in the Gulf of Panama. Gentle to locally moderate winds and
seas of 3 to 5 ft prevail across the remainder of the region. 
Hazy conditions are evident over the waters near Guatemala due to
the volcanic ash emissions of the past few days from the Fuego 
Volcano in Guatemala.

For the forecast, pulsing fresh to strong NE to E winds are 
expected in the Gulf of Papagayo through Thu morning, with 
moderate to fresh N winds pulsing in the Gulf of Panama. 
Otherwise, gentle to moderate winds and slight to moderate seas 
will prevail across the waters offshore of Central and South 
America through this weekend. Hazy conditions due to previous 
volcanic ash from the Fuego Volcano will prevail over the waters
near Guatemala. 

...REMAINDER OF THE AREA....

A cold front extends from 30N134W to 29N140W in the far
northwestern waters, and fresh to strong NW winds and seas of 8
to 11 ft in N swell prevail to the north of this front. 
Elsewhere, residual rough seas of 8 to 10 ft are noted north of 
12N and east of 135W associated with a weakening cold front over 
northwestern Mexico. Otherwise, a 1017 mb high is centered near 
21N123W, extending ridging through the remainder of the eastern 
Pacific waters. Moderate to locally fresh NE winds are noted 
north of the ITCZ and south of 20N, generally west of 110W. Seas 
of 5 to 7 ft prevail across areas south of 12N. 

For the forecast, the aforementioned cold front in the
northwestern waters will propagate toward the east into early
Fri, producing fresh to locally strong N to NW winds in the wake
of the front. Rough seas will expand toward the southeast through
the end of the week, with seas in excess of 8 ft occurring north
of 24N by late tonight, and north of 18N by Thu night. Peak seas
of 12 to 15 ft are expected north of 26N and west of 127W 
through late tonight, expanding to the south and east and 
impacting areas north of 23N between 117W and 140W through Fri 
morning. Elsewhere, a tightening pressure gradient between the
cold front and high pressure over the eastern Pacific will
support moderate to fresh trade winds and rough seas of 8 to 11
ft between 05N and 25N west of 110W through this weekend, with 
locally strong winds possible west of 135W on Thu.
