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
0355 UTC.
...SPECIAL FEATURES...
Significant rainfall event: A weakening stationary front extends
from E Cuba to the coast of Nicaragua. This boundary, along with
low level onshore flow, will allow for deep moisture to prevail in
the area. Heavy rainfall is expected through Thu, with 2 to 4
inches of rainfall possible primarily over northern Honduras,
eastern Guatemala, and coastal Belize, and isolated 4+ inches
possible along the windward slopes and near the north coast of
Honduras where the onshore flow persists. Marine interests in the
Gulf of Honduras should also be aware as scattered showers and
isolated thunderstorms will prevail in the area through today.
Please follow your local weather office for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of
Guinea-Bissau near 12N16W and continues southwestward to 05N20W.
The ITCZ extends from 05N20W to 01N35W and 00N50W. No significant
convection is noted near these boundaries.
GULF OF AMERICA...
A surface trough in the central Gulf and another one in the SW
Gulf support some cloudiness in the basin, although any shower
activity associated with this convection is very light. The Gulf
is under the influence of a strong high pressure that forces
moderate to locally fresh northerly winds and seas of 3-6 ft in
the eastern and SE Gulf, including the Florida Straits. Elsewhere,
moderate or lighter winds and slight to moderate seas prevail.
For the forecast, a stalled cold front in the NW Caribbean has
begun to drift southeastward. High pressure over the southern
Plains will shift east through Thu ahead of a low pressure area
moving into the lower Mississippi Valley, with a trailing cold
front that will move off the Texas coast Thu night. Fresh to
strong NW to N winds and building seas will follow the front as it
reaches from Panama City, Florida to Tampico, Mexico by Fri
evening. The low will rapidly deepen Fri as it moves into the
western Atlantic late Fri and Sat. This will reinforce the front
as it moves southeast of basin Sat, and usher in another blast of
arctic air across the Gulf. This will support winds to gale-force
winds over the eastern Gulf on Sat, and possibly off Veracruz in
the southwest Gulf, with rough to very rough seas across the
basin. Looking ahead, winds and seas will diminish from west to
east across the Gulf Sun and Mon as high pressure builds over the
northern Gulf following the front.
CARIBBEAN SEA...
Refer to the section above for details on the significant rainfall
even expected over the Honduras/Nicaragua area through Thu.
A stationary front extends from eastern Cuba to the coast of
Nicaragua. Stratocumulus clouds cover much of the NW Caribbean
behind the front. The tight pressure gradient between this front
and the ridge over the southern United States support fresh to
strong northerly winds and moderate to rough seas behind the
boundary. In the south-central Caribbean, a recent scatterometer
satellite pass captured fresh to strong NE winds. Seas in these
waters are 6-8 ft. Elsewhere, moderate or weaker winds and slight
to moderate seas are prevalent.
For the forecast, the aforementioned front has begun to drift
southward across the western Caribbean, as high pressure across
the N Gulf of America is starting to move eastward. Winds across
NW portions behind the front will increase to fresh to strong
tonight through Thu, and force it slowly southeastward, reaching
from E Cuba to the SE coast of Nicaragua Thu morning, then stall
and begin to weaken from E Cuba to near the Nicaragua- Costa Rica
border Thu evening through Fri. An unusually strong cold front
will move into the NW basin Sat morning and move southeastward,
merging with the old lingering front from E Cuba to central Panama
Sat evening, then reach from eastern Hispaniola to the NW coast
of Colombia by Sun evening. Strong to near gale- force N winds are
expected behind this front.
ATLANTIC OCEAN...
A stationary front extends from 31N48W to the SE Bahamas and
eastern Cuba. A few light showers are evident near this boundary.
Moderate to fresh northerly winds and seas of 6-8 ft are occurring
behind the boundary and south of 26N. Moderate to fresh SW winds
and seas of 8-13 ft are found north of 27N and east of the front
to 35W. Fresh to locally strong westerly winds and moderate to
rough seas are noted north of 30N and west of 65W.
The remainder of the tropical Atlantic is dominated by a 1025 mb
high pressure near 27N28W that extends southwestward to
Hispaniola. Moderate to fresh easterly winds and moderate to
locally very rough seas are found south of 24N and east of 60W.
The strongest winds and highest seas are evident in the eastern
Atlantic. Large northerly swell spreads across the eastern
Atlantic due to a strong low pressure well north of the area.
Rough to very rough seas are found north of 24N and east of 40W.
Elsewhere, moderate or weaker winds and moderate seas prevail.
For the forecast west of 55W, the aforementioned front will
meander across this area through Thu. High pressure across the
Gulf of America will build eastward into the W Atlantic and
freshen winds behind the lingering front Thu through Thu evening,
and nudge the front southward to the Atlantic approach to the
Windward Passage. An unusually strong cold front will enter the
western Atlantic waters on Sat. Associated low pressure is
forecast to deepen rapidly across the NW Atlantic this weekend,
inducing a large area of westerly gale- force winds across the
local waters N of 24N Sat through Sun evening. The front is
expected to reach from 31N74W to eastern Cuba Sat evening, and
from 31N62W to eastern Hispaniola Sun evening.

...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: A tight pressure gradient between
high pressure surging southward over eastern Mexico and relatively
lower pressure south of Mexico is resulting in 30 to 40 kt north
to northeast gale force winds in the Gulf of Tehuantepec region.
Seas are currently 10 to 16 ft with these winds. A ship reported
northeast winds of 35 kt a few hours ago near the location of
16N95.5W. These winds are forecast to diminish to fresh to strong
speeds Thu afternoon and continue into early on Fri. Seas will
subside to 8 to 11 ft Thu and to 6 to 8 ft on Fri. However,
arctic high pressure will again build southward over eastern
Mexico beginning Fri, with the gradient again tightening over
southeastern Mexico. North winds in the Gulf of Tehuantepec
region will reach near gale speeds Fri afternoon and to gale-
force late Fri night, possibly lasting until later in the
weekend. These winds may reach strong gale speeds late on Sat.
Seas in the Gulf of Tehuantepec will are expected to build to 11
to 17 ft late on Sat.
Please read the latest High Seas and Offshore Zone Forecast
issued by the National Hurricane Center at
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and
https://www.nhc.noaa.gov/text/MIAOFFPZ7.shtml for more details
on this event.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...Corrected
The monsoon trough axis extends from a 1010 low that is over
northwest Colombia westward to across southern Panama and
northwestward to 10N85W and to 14N91W, where it transitions to the
ITCZ to 02N100W to 06N115W to 06N130W and to beyond 06N140W.
Scattered moderate convection is within 120 nm southeast of the
trough between 86W-89W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A Gale Warning remains in effect for the Gulf of Tehuantepec
through Thu morning. See the Special Features section above for
more details.
The pressure gradient between surface ridging west of the Baja
Peninsula and a surface trough over the Baja and Gulf of
California region supports mostly moderate northwest winds in the
Gulf of California. Seas are 2 to 4 ft in the Gulf. Aside from
the Gulf of Tehuantepec gap wind event, winds over the remainder
of the Mexican waters are northwest to north in direction, and
gentle to moderate in speeds along with seas of 4 to 6 ft,
except for slightly higher seas of 5 to 7 ft east of 98W, where
northeast swell generated from the ongoing gale event has boosted
seas over these waters.
Isolated showers are noted from 18N to 23N and from just along
and inland the coast of Mexico west to 108W.
For the forecast outside of the Tehuantepec region, high
pressure over the U.S. Great Basin will continue to force
moderate to fresh northwest winds across the Gulf of California
before diminishing Sat night. Large northwest swell will reach
the waters west of Baja California Norte on Thu and Fri. There is
also potential for another set of northwest swell to move
through the waters west of Baja California Norte late this
weekend or early next week.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
A recent scatterometer satellite data pass shows fresh to strong
northeast winds in the Gulf of Papagayo region. Seas are 5 to 7
ft with these winds. North moderate to fresh gap winds are in
Gulf of Panama area along with seas of 6 to 8 ft. Elsewhere, the
ongoing Gulf of Tehuantepec gap wind gale event is generating
northwest to north producing seas up of to 10 ft across the
Guatemala and El Salvador offshore waters. Over the remainder of
forecast waters, winds are gentle to moderate in speeds along
with seas of 3 to 5 ft in northwest to north swell. Higher seas
of 5 to 6 ft are elsewhere over the offshore waters of northern
Costa Rica and southern Nicaragua.
For the forecast, high pressure over Central America and the
western Caribbean will maintain fresh to strong northeast to
east gap winds in the Papagayo region through Sat, except
reaching near gale speeds Thu night and Sat night into early Sun.
Gale-force winds are possible Sun through Mon. The same high
pressure will force moderate to fresh north to northeast winds in
the Gulf of Panama for the next several days. Elsewhere, a
strong Gulf of Tehuantepec gap wind event forcing large northwest
to north spreading across the Guatemala and El Salvador waters
should continue through Thu night. Looking ahead, a new
Tehuantepec event should again produce large to very large
northwest to north swell over Guatemala/El Salvador waters Sat
night into early next week.
...REMAINDER OF THE AREA...
High pressure of 1029 mb is located well north of the area at
35N136.5W. A ridge extends from the high south-southwestward to near
16N140W. A relatively weak pressure gradient between this high and
lower pressures in the deep tropics is forcing generally moderate to
fresh trades from the Equator to near 22N. An upper
-level trough is driving scattered showers and thunderstorms from
the ITCZ to about 20N between 118W and 1250W, which are leading to
locally strong northeast to east trades. Large northwest swell is
moving through the northwest part of the area, northwest of a line
from 30N130W to 20N140W. The ongoing Gulf of Tehuantepec gap wind
gale event is forcing seas of 8 to 10 ft in northwest to north swell
down to 03N between 90W and 110W. Elsewhere, moderate seas in mixed
swell prevail.
For the forecast, building high pressure north of our region will
enhance the trades, causing a larger area of fresh to locally strong
northeast winds and seas of 6 to 8 ft from Thu through Fri. The
large NW swell will continue moving southeastward reaching 08N by
Fri and gradually diminishing. On Fri evening, a new cold front will
reach 30N140W with fresh to strong southwest winds ahead of the
boundary. However, the cold front will gradually weaken while it
moves steadily eastward through the weekend. Large to very large NW
swell will follow the cold front and impact the northern waters this
weekend.
