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 1800 UTC surface analysis and satellite imagery through
2300 UTC.
...SPECIAL FEATURES...
Gulf of America Gale Warning: A 1012 mb low pressure located in
the NW Gulf near 28N95.5W will deepen as it tracks NE into
Louisiana by early Sun. The associated cold front will move SE
across the entire basin Sun through Mon evening. Strong reinforcing
arctic high pressure behind the front is expected to produce
near gale force winds across NW portions of the Gulf Sun and Sun
night, gale force winds over the offshore waters of Tampico Sun
night into Mon morning, and gales over the waters offshore
Veracruz Mon and Mon night. Seas are expected to quickly build
across the basin starting Sun reaching 16 or 17 ft over the SW
Gulf late on Mon. Conditions will improve quickly from NW to SE
Tue through Wed as the front moves SE into the NW Caribbean and
high pressure builds across the region. Mariners are advised to
keep up with the latest forecasts.
Please read the latest High Seas Forecast issued by the National
Hurricane Center at website:
https://nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough remains inland over Africa. The ITCZ extends
from the coast of Liberia near 05N09W to 01N25W to 02N40W to
00N50W. Scattered moderate convection is from the equator to 06N
between 15W and 21W. Similar convective activity is near 06N35W.
GULF OF AMERICA...
A warm front extends from N Florida westward to a 1012 mb low
pressure located near 28N95.5W. A strong arctic cold front
extends from the low center southward to inland Texas near
Brownsville. Scattered showers and thunderstorms are near the low
center and N of the warm front W of 90W. This convective activity
is affecting southern Louisiana. Fresh to strong easterly winds
are N of the front W of 90W based on scatterometer data with seas
of 3 to 5 ft. South of the front W of 90W, moderate to fresh SE
to S winds with moderate seas are W of 90W while gentle to
moderate SE winds and slight to moderate seas are E of 90W.
For the forecast, the low pressure will deepen as it tracks NE
into Louisiana by early Sun. The associated cold front will move
SE across the entire basin Sun through Mon evening. Please, see
the Special Features section for more information about these
features.
CARIBBEAN SEA...
The most recent satellite derived wind data indicate moderate to
locally fresh trades across most of the basin, with seas of 3 to
5 ft, except 5 to 7 ft near the coast of Colombia. A surface
trough is analyzed over eastern Cuba and Jamaica. This trough is
generating some convective activity over eastern Cuba. Patches of
low level moisture, embedded in the trade wind flow, are moving
across the area producing isolated to scattered passing showers.
Large E swell over the Tropical N Atlantic is bringing seas of 6
to 8 ft across the Atlantic passages of the Lesser Antilles.
For the forecast, broad high pressure over the east central
Atlantic will maintain mostly fresh trades over the eastern and
central Caribbean as well as the Tropical N Atlantic waters
through early next week, while fresh winds offshore of Colombia
pulse to strong at night through Sun, then to near gale force
afterward into midweek. Large E swell over the Tropical N Atlantic
will slowly subside into early next week, with seas lingering to
8 ft through early Wed. A cold front will enter the NW Caribbean
late Mon and begin to stall from eastern Cuba to the Gulf of
Honduras by late Tue into Wed, weakening to a shearline Thu.
Strong northerly winds will follow the front before briefly
diminishing to mostly fresh speeds on Wed, and increasing back
to fresh to strong on Thu as stronger high pressure builds
southward toward the NW Caribbean.
ATLANTIC OCEAN...
A cold front extends from near Bermuda westward to inland north
Florida just N of Cape Canaveral, FL. A surface trough is
analyzed E of the front and runs from 31N60W to just E of the NW
Bahamas. Some shower activity is associated with trough. The
cold front, that yesterday crossed the Canary Islands has
dissipated, but lingering N swell, with seas of 12 to 16 ft
persists near the Canary Islands. High pressure of 1030 mb
located W of the Madeira Islands near 31N24W dominates the
remainder of the forecast region. Under this weather pattern,
a large area of fresh to strong NE to E winds is noted from 10N
to 25N E of 30W, including the Cabo Verde Islands, and from 07N
to 23N between 30W and 50W. Seas of 8 to 10 ft are within these
winds. Moderate to fresh trades are occurring from 10N to 20N W
of 50W to the Lesser Antilles. An altimeter pass indicates seas
of 8 to 9 ft just NE of the Leeward Islands. Moderate or weaker
winds and moderate seas prevail elsewhere. A band of transverse
high clouds associated with very strong southwesterly winds aloft
persist across the tropical Atlantic, extending from NE South
America all the way to W Africa.
For the forecast west of 55W, the trough and ridge will shift
slowly NE through tonight. Fresh to strong S to SW winds will
develop over the NW forecast waters Sun evening through early Mon
in advance of a strong Arctic cold front that is expected to move
offshore northeastern Florida early Mon. Winds to near gale force
will develop just N of the area early on Mon. The front will reach
from near 31N70W to the NW Bahamas and Straits of Florida Mon
evening, from near 31N56W to the SE Bahamas and eastern Cuba Tue
evening, then weaken as it reaches from near 31N51W to 26N60W then
stationary to the SE Bahamas and eastern Cuba Wed afternoon.
Fresh to strong northerly winds and rough seas are expected W of
the front Mon afternoon through Tue afternoon, becoming mostly
fresh NE winds Tue night and Wed within about 180 nm NW of the
frontal boundary. The frontal boundary will become nearly
stationary from near 29N55W to 25N66W and to near 20N70W by late
Thu as another strong cold front moves over the NW forecast
waters.

...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: The next gap wind event across
the Tehunatepec region is slated to begin early Mon morning as a
ridge builds across the eastern slopes of the Sierra Madre
Mountains in Mexico, behind a cold front moving across the Gulf
of America. Wind are forecast to suddenly increase to 35-40 kt,
with seas building to 9 to 12 ft by late Mon morning. Looking
ahead, winds will further increase to minimal storm force by Mon
night with seas building to 20 to 22 ft. Gusty winds to near
hurricane force may occur on Mon night. A Storm Warning will
likely be issued tonight. Large seas generated from this strong
gap wind event will spread well away from the Tehuantepec area,
with seas 12 ft or greater reaching as far south as 10N by Tue
morning. Marine interests transiting across or in the Gulf of
Tehuantepec early next week should be aware of this upcoming gap
wind event, and take the necessary action to avoid this hazardous
marine conditions over the affected waters. Winds are forecast
to diminish below storm force by late Tue morning but strong gale
force winds of 40-45 kt will persist. Gale conditions are then
forecast to continue through early Wed morning.
Please read the latest High Seas Forecast issued by the National
Hurricane Center at
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details
on this event.
Of note: The monthly distribution of Tehuantepec events shows
that the largest number of gale force events occurs in December.
Storm-force events occur most often in January.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from a 1010 mb low pressure located
over northern Colombia near 10N75W to 07N90W to 06N101W. The
ITCZ continues from 06N101W to 07N125W to beyond 07N140W. A
surface trough is within the ITCZ and runs from 12N116W to
06N120W. Scattered moderate convection is noted near the trough
axis from 09N to 12N between 115W and 120W. Elsewhere convection
is limited.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A surface trough extends over NW Mexico and the southern Gulf of
California. The pressure gradient between a ridge across the
Baja California offshore waters and this trough supports fresh to
strong NW winds between Cabo San Lucas and Punta Eugenia with
seas of 4 to 6 ft. Mainly fresh NW winds are noted N of Punta
Eugenia, including the Bay of Sebastian Vizcaino, with moderate
seas. Fresh to strong SW winds are also seen from 22N to 24N
within about 90 nm E of the trough axis, including the entrance
to the Gulf of California. Light to gentle winds and moderate
seas in NW swell dominate the remainder of the Mexican offshore
forecast waters, including the Tehuantepec area.
For the forecast, the aforementioned surface trough will move
inland Mexico tonight while dissipating. The associated winds
will diminish to 15 kt by this evening, with the exception of 20
kt westerly winds in the vicinity of Los Cabos. Looking ahead,
a very strong gap wind event is slated to begin in the Tehuantepec
region Mon morning, with winds rapidly increasing to storm force
by Mon evening. Very rough seas will be associated with these
wind speeds. Please, see the Special Features section for more
information on this event.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Moderate to locally fresh NE to E winds are across the Papagayo
region and downwind to about 88W. Seas are 4 to 6 ft within
these winds. Moderate N winds with slight to moderate seas
prevail in the Gulf of Panama. Elsewhere, light to gentle with
moderate seas in mixed SW and NW swell prevail.
For the forecast, high pressure N of the area will support fresh to
strong NE to E winds and rough seas in the Papagayo region through
early Sun morning. Fresh to strong winds in this region will resume
again Mon night into Tue, and reach near gale force speeds by Tue
evening, with seas building to 10 or 11 ft. Moderate to locally
fresh N winds will continue to pulse in the Gulf of Panama through
Thu night. Elsewhere, winds will be moderate or weaker through
the middle of the next week. Seas generated by a very strong gap
wind event in the Tehuantepec region will propagate across the
offshore forecast waters of Guatemala and El Salvador beginning
Mon evening. The highest seas, in the 12 to 19 ft range in NW
swell, are expected on Tue. Rough seas may persist through Thu
night.
...REMAINDER OF THE AREA...
A ridge extends southward from a 1025 mb high pressure located
near 34N136W across the northern forecast waters, particularly N
of 15N and W of 110W. The pressure gradient between the ridge
and lower pressure in the vicinity of the ITCZ is promoting an
area of moderate to fresh trades N of the ITCZ to about 17N and
W of 125W. Seas are 5 to 7 ft within these winds based on
altimeter data. Elsewhere, winds are moderate or weaker and seas
are moderate in mixed NE wind wave and long period NW swell.
For the forecast, high pressure will continue to build southward
across the forecast region on Sun, with a high pressure cell
developing near 32N136W. The high pressure will move E through
Tue as a cold front approaches the NW corner of the forecast
waters. The front will reach from 30N135W to 26N140W by Mon
night, and from 30N133W to 24N140W by Tue morning. Fresh to
strong winds are expected ahead and behind the front by Mon
night, then winds will diminish 10 to 15 kt on Tue. Rough seas
are forecast in the wake of the front.
