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 1200 UTC surface analysis and satellite imagery through
1626 UTC.
...SPECIAL FEATURES...
Meteo-France Gale Warning: Meteo-France forecasts gale-force S or
SW winds, veering to W or SW in Madeira through 04/03 UTC, the
Northern Canary Islands from 03/12 UTC through at least 03/21
UTC, and SW in Agadir from 03/12 UTC through 03/21 UTC. Rough to
very rough seas will likely accompany these winds. For more
details, refer to the Meteo-France High Seas Forecast listed on
their website https://wwwmiws.wmo.int
...MONSOON TROUGH/INTERTROPICAL CONVERGENCE ZONE...
The monsoon trough enters the Atlantic Ocean near 09N14W and
extends southwestward to 04N19W. The ITCZ extends from 04N19W to
02S41W. Scattered moderate to isolated strong convection is noted
south of 07N along the ITCZ.
...GULF OF AMERICA...
A broad area of low pressure has been analyzed over norther
Mexico and southeast Texas, and the subtropical ridge extends
from the western Atlantic through the central Gulf of America. The
pressure gradient between these features is supporting fresh to
strong S to SE winds west of 85W, with moderate to fresh SE winds
occurring to the east. Rough seas are found west of 89W while
moderate seas prevail elsewhere.
For the forecast, a strong pressure gradient between the Bermuda
High to low pressure over N Mexico/Texas will continue forcing
fresh to near gale SE winds across the Gulf through Sat afternoon.
On Sat night, a strong late-season cold front will emerge off of
the Texas coast. Fresh to near gale N winds and rapidly building
seas will follow the front over the W Gulf on Sun and Mon with N
gales possible near Tampico on Sun morning. Looking ahead to Mon
morning, the cold front will extend from the Florida panhandle to
the Bay of Campeche with N winds fresh to strong following the
front and near gale NW winds off of Veracruz.
...CARIBBEAN SEA...
A 1010 mb low has been analyzed just off the coast of Colombia
near 10N75W, and ridging extends over the rest of the Caribbean.
The pressure gradient between these features is supporting fresh
to strong trades and rough seas in the central and eastern
Caribbean, with similar winds near the Gulf of Honduras. Winds are
mainly moderate to fresh elsewhere. Away from the aforementioned
areas, seas of 4 to 7 ft prevail in the northwestern Caribbean.
For the forecast, a strong pressure gradient from the Bermuda
High to the Colombian Low will continue to produce fresh to strong
trades across the Caribbean through Sat morning with near gales
just north of Colombia. From Sat through early next week, the
Bermuda High weakens leading toward reduced winds. However, strong
trades will still continue north of Colombia, south of Hispaniola
and over the Gulf of Honduras on Sat and Sun. Looking ahead to
Mon, as the weakened Bermuda High shifts eastward, trades across
the Caribbean will be reduced to only moderate to fresh.
...ATLANTIC OCEAN...
Refer to the section above for details on a Gale Warning in
effect for the Meteo-France area.
The Atlantic basin is dominated by 1036 high pressure centered
north of the area near 42N66W, with the subtropical ridge axis
extending southward into the subtropical and tropical Atlantic. A
complex low pressure system has been analyzed between the Canary
Islands and the Azores. A cold front associated with the complex
low pressure enters our waters near 31N15W and extends
southwestward to 30N30W. These features are supporting W to NW
fresh to gale-force winds north of 27N and east of 20W per latest
observation from satellite derived winds. Associated large seas
of 8 to 12 ft cover the waters north of 21N between the W coast of
Africa and 35W, with seas of 12 to 16 ft occurring N of 26N
between 14W and 35W. Fresh to strong NE to E winds and seas of 7
to 11 ft prevail across much of the basin W of 30W and S of 25N.
The remainder of the Atlantic is seeing moderate to fresh trades
and moderate seas.
For the forecast west of 55W, a strong Bermuda High will continue
to force fresh to strong trades south of 25N through Fri night.
As the Bermuda High weakens on Sat through early next week, fresh
to strong trades will be restricted to near the SE Bahamas and the
Windward Passage. Beginning Sat night, a large N swell will start
impacting the zones east of 65W and will continue through at
least Mon. Looking ahead, fresh to locally strong S winds are
slated to develop off the coast of N Florida on Sun ahead of a
cold front moving through the SE United States. The cold front is
forecast to move off of the coast early next week.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Thu Apr 3 2025
Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 1800 UTC surface analysis and satellite imagery through
2100 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends westward from a 1008 mb low pressure
located over northern Colombia near 10N74W to 06N93W to 06N110W.
The ITCZ continues from 06N110W to 00N130W to 05S140W. Scattered
moderate to isolated strong convection can be found from 02N to
05N between 78W and 81W, from 00N to 02N between 80W and 84W,
from 00N to 05N between 92W and 96W, and from 02N to 05N between
100W and 106W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
High pressure of 1025 mb is located near 28N136W. Its associated
ridge extends southeastward to near the Revillagigedo Islands.
This pattern is supporting moderate to locally fresh NW to N
winds west of Baja California. Seas of 8 to 10 ft in NW swell
dominate the waters N of Cabo San Lazaro. Moderate NW to N winds
and seas of 5 to 7 ft in mixed NW and SW swell are present from
Cabo San Lucas to near the Revillagigedo Islands. In the Gulf of
California, gentle to moderate winds and seas of 2 to 4 ft are
noted. Light and variable winds and moderate seas primarily in SW
swell prevail across the remainder of the Mexican offshore
waters, including the Gulf of Tehuantepec.
For the forecast, a ridge will remain in place across the offshore
forecast waters of Baja California supporting moderate to fresh
NW winds through Sun. In the Gulf of California, gentle to moderate
winds are expected through Sat, then wind will increase to fresh
to locally strong speeds across the central and southern parts
of the Gulf Sat night through Sun night as the pressure gradient
tightens between the ridge to the W and a low pressure over Mexico.
Rough seas currently affecting the waters N of Cabo San Lazaro
will subside to below 8 ft by Fri afternoon, with another set of
long period NW swell arriving by early next week. Looking ahead,
a late season gap wind event is expected in the Gulf of Tehuantepec
late Sun night. Gale conditions are possible early next week.
Climatologically, the first gale-force event of the season occurs
in mid-October, with the final gale-force event occurring in late
March or early April. Occasionally, gale-force events may occur
as early as September, and as late as May.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Recent scatterometer data provide observations of moderate to
locally fresh E winds across the Papagayo region and downwind to
near 90W while light to gentle winds and seas at 3 to 5 ft are
evident elsewhere off Central America and Colombia. Farther south,
gentle to moderate E to SE winds with 4 to 6 ft seas in a mixed
of SW and NW swells prevail between Ecuador and the Galapagos
Islands.
For the forecast, pulsing winds to fresh to strong speeds are expected
in the Papagayo region through Sat night, mainly during nighttime
and early morning hours. Gentle to moderate E to SE and moderate
seas are forecast across the offshore waters of Guatemala and El
Salvador through Sun as the Atlantic ridge extends southwestward
across northern Central America. A mix of SW and NW swells will
keep moderate seas between Ecuador and the Galapagos Islands
through Fri. Elsewhere, light to gentle winds and moderate seas
will prevail.
...REMAINDER OF THE AREA....
High pressure of 1025 mb is located over the NW waters near 28N136W.
Its associated ridge covers most of the waters N of 10N and W of
110W. This pattern is supporting fresh to locally strong trade
winds and seas of 7 to 9 ft seas in a mixed of NE and NW swell
from 10N to 20N W of 125W based on scatterometer and altimeter
data. Moderate to locally fresh winds and moderate seas prevail
elsewhere under the influence of the ridge.
For the forecast, the high pressure will move NE and N of the
forecast area by Sat as a cold front approaches to 30N140W. The
cold front will move across the NW through MOn while gradually
weakening. This should allow winds to diminish slightly across
the trade wind belt. High pressure will follow the front with the
ridge axis along 30N by Mon night. A new set of large NW swell
will reach 30N140W by Sat afternoon, with seas building up to
around 14 ft near 30N140W by early Sun. This swell event will
continue to propagate across the forecast waters through Mon.
Seas of 8 ft or greater will cover the waters west of a line
from Punta Eugenia to 05N140W by Mon evening.
