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
1620 UTC.
...MONSOON TROUGH/ITCZ...
The monsoon trough reaches the Atlantic through the coast of
Liberia near 06N09W and continues southwestward to 02N16W. The
ITCZ extends from 02N16W to 02S43W. Scattered showers are along
the ITCZ and monsoon trough.
GULF OF AMERICA...
A new cold front extends from SE Louisiana to NE Mexico. Fresh to
strong NE winds and building 4-6 ft seas follow the front in the
NW Gulf. Scattered moderate convection is from 24N to 28N west of
94W, and within 120 nm ahead of the remainder of the front.
Elsewhere, the diurnal trough is analyzed in the Bay of Campeche,
and weak troughs are analyzed in the E Gulf and inland over the
Florida Peninsula. Scattered showers are near these troughs.
Gentle to moderate trades, and 2-4 ft seas, prevail across the
waters ahead of the front.
For the forecast, the aforementioned cold front will reach from
near Apalachicola, Florida to 26N95W and to 19N95W by this
evening, then slow down as it reaches from near Tampa to 26N92W
and stationary to 18N94W Mon afternoon, from southwest Florida to
25N90W to 24N94W and stationary to 18N94W late Mon night, then
stall and perhaps linger into most of Thu. Scattered showers and
thunderstorms, some with gusty winds, are expected near the
front. Fresh to strong northeast northeast winds and rough seas
will develop behind the front across portions of the western Gulf
into Mon, then similar conditions will materialize over the NE
Gulf Tue through Thu. Near gale, to at times gale, conditions are
possible near Florida Wed and Wed night.
CARIBBEAN SEA...
The pressure gradient between subtropical Atlantic high pressure
and the Colombian low continues to support fresh to locally strong
trades offshore Colombia. Seas are analyzed to be 7-9 ft, per the
latest satellite altimeter data received for the region.
Elsewhere, moderate to fresh trade winds and 4-7 ft seas are noted
in the eastern and central basin, and gentle trades with 2-4 ft
seas are analyzed in the western basin. Scattered moderate
convection is apparent across the southern Windward Islands.
For the forecast, high pressure north of the basin will shift
eastward through Mon allowing for pulsing strong winds and rough
seas offshore Colombia to diminish. A trough just north of
Hispaniola will drift west-northwestward toward the Bahamas
through Tue. The gradient between it and central Atlantic high
pressure will maintain fresh trade winds across the eastern
Caribbean, with gentle to moderate winds elsewhere. Trades may
increase again in the south-central Caribbean beginning during the
middle part of the week as a new and stronger area of high
pressure builds southward over the western Atlantic in the wake of
a cold front.
ATLANTIC OCEAN...
Areas of high pressure centered near the Azores and Bermuda are
dominating the basin. Satellite scatterometer data indicates
moderate to fresh trades north of 18N west of 50W, across most of
the western Atlantic offshore zones. Seas have built to 8-10 ft
from 18N to 28N between 60W and 76W, including along the eastern
islands of the Bahamas and Turks and Caicos. Scattered showers are
also affecting these waters. Elsewhere across the tropical
Atlantic, trades are moderate or weaker with 4-7 ft seas in open
waters.
For the forecast west of 55W, fresh to strong east winds and
rough seas E of the Bahamas and N of Hispaniola and Puerto Rico
will gradually decrease into Mon as Bermuda high pressure moves E
and weakens. In the wake of the high, a cold front will move off
the SE U.S. coast early Mon, then slide slowly eastward through
early week. As it does, a westward moving inverted trough N of
Hispaniola will likely interact with the front and low pressure
may form as a result along the front in the vicinity of the
Bahamas. Any low that forms will track northeastward along the
frontal boundary, then N of the region Wed into Thu. The pressure
gradient between the low pressure and high pressure building in to
the SE U.S. will lead to widespread strong to near gale-force
northeast winds N and W of the cold front Tue through late week,
along with very rough seas. Mariners are advised to keep up with
the latest forecast and stay informed abreast for possible gale
conditions developing as early as Tue.

1605 UTC Sun Apr 5 2026
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 1200 UTC surface analysis and satellite imagery through
1400 UTC.
...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: Building ridge across the
eastern slopes of the Sierra Madre Mountains in Mexico will
force the next gap wind event in the Gulf of Tehuantepec. Winds
are in the process of increasing to 20 to 30 kt, with seas
building to 8 ft later today. Winds will further increase to
gale force overnight tonight into early Mon, with seas building
to 12 or 13 ft on Mon night into early Tue. Gusty winds to near
storm force may occur. These marine conditions are forecast to
persist through early Tue morning. Seas generated from this gap
wind event will spread well away from the Tehuantepec area, with
seas 8 ft or greater reaching as far south as 11N Mon night into
Tue. Please read the latest High Seas Forecast issued by the
National Hurricane Center at website:
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 07N78W to 06N95W. The ITCZ
stretches from 06N95W to 06N120W to beyond 03N140W. A second
ITCZ is located south of the Equator and runs from 03.4S117W to
beyond 03.4S120W. Scattered moderate isolated strong convection
is present from 05N to 08N between 80W and 84W, and within 90 nm
either side of the ITCZ between 120W and 140W. Similar convection
is within 150 nm of the coast of Colombia S of 06N.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please refer to the Special Features section for details on a
developing Gulf of Tehuantepec Gale Warning.
Otherwise, gentle to moderate winds are found N of 22N, including
offshore Baja California and in the Gulf of California, with
high pressure ridging W of the peninsula and troughing over NW
Mexico. Light to gentle winds are found elsewhere away from the
Gulf of Tehuantepec. Seas are 6-7 ft W of 110W in mixed S and NW
swell, and 6 ft elsewhere in mainly S swell from the entrance of
the Gulf of California S-SE to offshore SW and southern Mexico.
Seas are 2-4 ft in the remainder of the Gulf of California.
For the forecast, other than the developing Gale Warning in the
Gulf of Tehuantepec, NW swell off Baja California will subside
through tonight. Gentle to moderate winds and slight seas will
prevail in the Gulf of California through much of the week,
pulsing to moderate to fresh in the central portion early week.
Moderate to locally fresh NW winds and moderate seas are expected
off Baja California through the forecast period. However, winds
may increase to strong N of Punta Eugenia Thu night.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
High pressure north of the Caribbean is supporting fresh to
locally strong easterly trade winds across the Gulf of Papagayo
region. Seas in these waters are 5-7 ft. Farther east, moderate
to locally fresh northerly winds and moderate seas are present in
the Gulf of Panama. Meanwhile, light to gentle winds and
moderate seas dominate the remainder of the offshore forecast
waters. Some active convection is present offshore Colombia and
from near the Azuero Peninsula SSW as described above.
For the forecast, fresh to strong gap winds are expected during the
nighttime and early morning hours in the Papagayo region and
downwind to about 89W through the forecast period. Moderate to
locally fresh northerly winds are forecast in the Gulf of Panama
through much of the week. A gap wind event in the Tehuantepec
region will produce seas to 8 ft in the far offshore waters of
Guatemala Mon night through Tue. Light to gentle winds and
moderate seas will prevail elsewhere.
...REMAINDER OF THE AREA...
A deep upper level trough and a weak surface trough combine to
produce abundant cloudiness and some showers over the western
waters, especially N of 17N and W of 120W. At the surface, a
1020 mb high pressure near 30N130W, wedged between two low
pressure systems, dominates the remainder of the tropical eastern
Pacific. Moderate to fresh easterly winds N of the ITCZ and W of
110W. Seas in these waters remain around 6 to 8 ft. Elsewhere,
moderate or lighter winds and moderate seas are prevalent.
For the forecast, ridging will support moderate to locally fresh
easterly winds and moderate to locally rough seas across the
trade wind zone into the middle of the week, supporting seas to
around 8 ft. A cold front is forecast to reach 30N140W tonight,
and extend from 30N137W to 24N140W by Mon morning. Gentle to
moderate winds are forecast on either side of the front. Seas
will briefly build to 9 ft behind the front Mon night into Tue.
Seas may build to around 8 ft in southerly swell near 03.4S by
the end of the week.
