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 0000 UTC surface analysis and satellite imagery through
0540 UTC.
...MONSOON TROUGH/ITCZ...
The monsoon trough axis enters the Atlantic near 06N11W and
extends southwestward to 01N21W. The ITCZ continues from 01N21W
to 01N35W to the coast of Brazil at 00N48W. Scattered moderate
convection is ongoing from 06S to 05N between 12W and 31W, and
from 01S to 04N between 01W and 12W.
...GULF OF AMERICA...
A weak surface ridge extends from the SW N Atlantic waters to just
east of 90W while a broad area of low pressure centered by a 996
mb low over east-central Mexico covers the western half of the
basin. The resultant pressure gradient between these two features
is supporting fresh to locally strong SE winds W of 88W and gentle
to moderate SE winds elsewhere. In the northern Gulf, a stationary
front extending from SE Georgia to southern Louisiana to southern
Texas is generating scattered heavy showers and tstms mainly over
the coastal waters from the Florida Panhandle to Houston, Texas. the Gulf
of HondurasSeas are 5 to 7 ft W of 88W and 2 to 5 ft E of 88W.
For the forecast, the pressure gradient between high pressure
over the SE United States and low pressure over Mexico will
support fresh to locally strong winds over the W half of the
basin. Gentle to moderate winds will prevail elsewhere. Winds will
weaken across the basin Thu as the next front approaches. The
front will reach across the western zones Thu night, from SE
Louisiana to Veracruz, Mexico by early Fri, from the western
Florida Panhandle to the eastern Bay of Campeche by early Sat,
then from the Florida Big Bend to the Yucatan Peninsula early Sun.
Smoke from agricultural fires in southeastern Mexico is creating
hazy conditions in some sections of the western Gulf, with the
lowest reported visibility near the SW Gulf coast.
...CARIBBEAN SEA...
A broad area of low presure SSE of Bermuda is allowing the
continuation of a weak pressure gradient across the Caribbean,
which is resulting in gentle to moderate trade winds across most
of the Caribbean, except for localized fresh winds near the Gulf
of Honduras, through the Windward Passage and the lee side of Cuba.
Seas are 2 to 4 ft across the most of the basin, except 5 to 6 ft
in the Gulf of Honduras. Otherwise, isolated showers are occurring
over the NE Caribbean due to the proximity of a surface trough
from the east.
For the forecast, moderate to fresh east to southeast winds will
pulse north of Honduras, increasing to fresh to strong speeds
nightly tonight through Fri night. Unsettled weather is expected
to continue over the eastern Caribbean through mid-week. Winds
will pulse to fresh nightly near the Windward Passage. Gentle to
moderate trades and slight to moderate seas are expected over the
remainder of the basin through Fri, including in the Tropical N
Atlantic, before increasing slightly this weekend. Winds will
start to increase to fresh in the central Caribbean and off
Colombia Fri night, then to fresh to strong Sat through the
remainder of the upcoming weekend as the pressure gradient
tightens.
...ATLANTIC OCEAN...
The pressure gradient between a low centered near 26N64.5W with
associated trough and high pressure centered over the central
Atlantic is supporting fresh to locally strong northeast winds and
moderate to rough seas north and northeast of the low. Scattered
heavy showers and tstms are also associated with the low and
affecting mainly the waters N of 25N between 59W and 66W. Another
surface trough E of the Leeward Islands is supporting similar
shower activity from 15N to 23N between 51W and 60W. Otherwise, a
broad surface ridge covers the remainder central and eastern
subtropical waters with a weakening stationary front intersecting
the ridge from 31N19W to 22N35W to 25N50W. Aside from the area of
low pressure SSE of Bermuda mentioned above, winds are moderate or
weaker elsewhere, and seas are moderate as well.
For the forecast west of 55W, winds and seas associated with the
low and surface trough will gradually shift westward through mid-
week as both drift westward. Winds and seas will start to
decrease Wed night as the low and trough start to weaken. A
stationary front along and just offshore the southeastern U.S.
coast will gradually lift back northwest as warm front through
mid-week, then may slowly push offshore again at the end of the
week and into the upcoming weekend.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Wed May 07 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 0000 UTC surface analysis and satellite imagery through
0345 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from northwest Colombia to 08N83W
to 11N95W to 09N110W to 08N118W, where it transitions to the
ITCZ to 06N130W to 06N140W. Scattered moderate to isolated
strong convection is seen within 120 nm south of the trough
between 103W-106W and within 60 nm of the trough between
106W-114W. Scattered moderate convection is within 180 nm
north of the ITCZ between 120W-123W, between 125W-133W and
within 60 nm of the trough between 81W-85W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Weakening high pressure remains well to the NW of the Baja
California waters, and extends a broad ridge southeastward to
south of the Revillagigedo Islands near 14N105W. A broad surface
trough is across the waters of southern California, Baja Norte,
and the northern Gulf of California. A second weak trough lingers
across the southern Gulf of California, extending from central
Sinaloa to just west of Las Tres Marias. Moderate to fresh
NW winds are along and just offshore the southwestern tip of the
Baja Peninsula. Moderate to locally fresh NW winds continue from
there southeastward across the near and offshore waters of Cabo
Corrientes to central Michoacan. Seas across this area are 6 to 8
ft in NW swell. Elsewhere across the Baja offshore waters, light
to gentle NW winds prevail as noted in the latest scatterometer
satellite data passes. Seas are 6 to 9 ft in subsiding NW swell.
Across the Gulf of California, gentle to moderate S to SW winds
are over the northern Gulf, while light and variable wind are
over the central part of the Gulf and gentle NW to N winds are
over the southern section. Seas in the Gulf are 3 ft or less
except for higher seas of 3 to 5 ft in SE swell are in he far
southern part and in the entrance. Elsewhere across the remaining
Mexican waters to Tehuantepec, winds are light to gentle along
with seas of 5 to 7 ft in SW swell.
For the forecast, the broad ridge across the region will generally
persist through early Fri before high pressure builds modestly
across the Baja California waters over the upcoming weekend.
Gentle to moderate winds across the Baja waters tonight will
increase modestly through Thu night. NW swell moving through the
area waters has peaked and will begin to subside tonight through
Wed. Looking ahead, a late season northerly gale event is
possible across Tehuantepec Sat night and Sun night, with strong
N gap winds expected to begin across Tehuantepec Sat morning.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
The weather remains unsettled across the waters east of about
90W as monsoonal SW to W low level winds are now dominating the
far eastern Tropical Pacific. Earlier seen large clusters of
moderate to strong thunderstorms from 03N to 08N between 81W and
88W have recently diminished in coverage. satellite imagery
shows scattered showers and thunderstorms along and just offshore
the coast Costa Rica and northern Panama. Light and variable
winds generally prevail north of the monsoon trough, along about
11N, and only gentle to moderate gap winds are occurring across
the Papagayo region. Gentle to moderate SW to W winds prevail
across most of the waters south of the trough and into the
coasts. Seas of 4 to 7 ft in SW swell are over the Central
American offshore waters, except for higher seas of 6 to 8 ft in
new S to SW swell south of and near the Galapagos Islands.
For the forecast, gentle to locally moderate breezes will
persist across the waters off Central America, Colombia and
Ecuador, with primarily moderate SW swell through Thu. New SW
swell is expected to enter the waters north of the Equator and
build across the area waters tonight through Thu.
...REMAINDER OF THE AREA....
High pressure just north of the area has collapsed today, ahead
of an approaching cold front. A broad ridge still persists across
the regional waters W of 105W. Moderate to fresh N to NE winds
prevail west of 125W and north of 09N, and are gentle to moderate
between 110W and 125W. NW to N swell continues to dominate the
waters N of 22N and E of 132W, where seas are 8 to 10 ft. W of
132W seas are around 6 ft, while seas in the trade wind zone from
09N to 22N are 7 to 9 ft. Moderate or lighter winds and moderate
seas are noted elsewhere south of the ITCZ.
For the forecast, the weakening high pressure ridge across the
region W of 110W will generally persist through early Fri. A
weak cold front may approach 30N140W late Fri night or early Sat.
High pressure building behind it will overtake the weakening
front through Sun night. A tightening gradient will act to
expand the areal coverage of the fresh trade winds northward to
near 26N by Sun evening. Seas with these trades are expected to
be in the 6 to 8 ft range.
