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
0430 UTC.
...TROPICAL WAVES...
An central Atlantic tropical wave is analyzed with axis along 38W
from 11N southward, and moving westward at 5 to 10 kt.
An central Caribbean tropical wave is near 70W from 15N southward
across western Venezuela, and moving westward at 10 to 15 kt.
Scattered moderate to isolated strong convection is evident from
14N to 16N between 63W and 70W.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic near 12N16W, then curves
southwestward to 06N25W. An ITCZ continues from 06N25W to 04N35W,
then resumes from 02N41W to 02N49W. No significant convection is
evident at this time.
...GULF OF AMERICA...
A sharp mid/upper trough reaches from northeast Texas across the
western Gulf to the Yucatan Peninsula. Abundant moisture and
divergence aloft ahead of the trough is supporting scattered moderate
to strong convection in the southerly flow across the central
Gulf. Frequent lightning, gusty winds, and locally rough seas are
likely near these thunderstorms. Weak ridging extends from north-
central Atlantic to Florida, supporting fresh SE winds across the
Florida Straits, and moderate SE winds over the eastern Gulf where
seas are 3-5 ft. A weak pressure gradient elsewhere across the
central and western Gulf is supporting light to gentle breezes
with 1-3 ft seas.
For the forecast, the Atlantic ridge will sustain gentle to
moderate E to SE winds through Thu. The exception will be evening
pulses of fresh to strong winds off the northern Yucatan. An
upper-level trough across the western Gulf should continue to
couple with abundant tropical moisture to produce scattered heavy
showers and strong thunderstorms over the central and northeastern
Gulf through at least Wed. These thunderstorms are capable of
producing gusty winds, frequent lightning, limited visibility, and
locally rough seas. Mariners are urged to keep up to date with
the latest forecast.
...CARIBBEAN SEA...
Scattered showers and thunderstorms remain active across the far
northwest Caribbean and the Yucatan Channel due to divergent flow
aloft ahead of a sharp mid/upper trough northwest of this area.
Elsewhere, no significant convection is active at this time
across the basin. Strong ridging over the Atlantic along with
lower pressure far south over Colombia is supporting fresh to
strong trade winds across the central Caribbean, with near-gale
force winds possible off the coast of central Colombia. Moderate E
to SE winds are noted elsewhere. Seas are 8-10 ft in the central
Caribbean, and 4-7 ft elsewhere.
For the forecast, tight pressure gradient between high pressure
in the western Atlantic and the Colombian low will continue to
support fresh to strong trades over the central Caribbean with
rough seas through Thu night. These winds are expected to pulse to
near-gale force off Barranquilla, Colombia, during night-time and
morning hours into Thu. Trades in the Gulf of Honduras and north
of Jamaica will reach fresh to strong each evening through the
same period. By Fri, most of the basin should experience moderate
with locally fresh winds and moderate seas, except the south-
central basin which fresh to strong winds and rough seas will
remain through the weekend.
...ATLANTIC OCEAN...
A cold front is analyzed from 31N35W to 26N41W, then becomes
stationary to 30N63W. Fresh to strong NE winds and 8 to 10 ft
seas are present near and behind the front. Farther south, fresh
to strong SE winds and 8-10 ft seas are active from 15N to 26N
and west of 58W into the central Bahamas. Moderate to fresh trade
winds and 5-7 ft are noted elsewhere south of 18N. Gentle breezes
and 4-6 ft are noted elsewhere.
For the forecast west of 55W, fresh to strong winds with moderate
to rough seas will prevail across waters south of 25N through
Wed, including the Great Bahama Bank, as Atlantic high pressure
shifts southeastward, tightening the pressure gradient. As the
high weakens Wed night, winds and seas will diminish. The front
will slide SE tonight and out of the region by Tue. Fresh NE winds
and rough seas N of it will diminish Tue.

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 0600 UTC surface analysis and satellite imagery through
0800 UTC.
...TROPICAL WAVES...
The axis of a tropical wave is near 88W and N of 03N, moving
west at 10 kt. Nearby convection is noted in the ITCZ/monsoon
trough section below.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 09N84W to 08N102W. The ITCZ
extends from 08N102W to 10N133W to 08N140W. Scattered moderate
to isolated strong convection is noted from 01N to 08N between
84W and 100W, and from 03N to 12N between 112W and 140W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A weak ridge extends from 30N135W through the Revillagigedo
Islands. The pressure gradient between the ridge and a surface
trough over the Gulf of California is supporting moderate to
fresh winds across the waters west of Baja California. Gentle to
moderate winds are south of Baja California and west of Cabo
Corrientes. Moderate to fresh gap winds are funneling into the
Gulf of California. Light to gentle winds prevail elsewhere.
Seas are in the 5-7 ft range over the open waters, and 1-3 ft in
the Gulf of California.
For the forecast, moderate to fresh winds will prevail offshore
Baja California through the end of the week. A set of NW swell
will move into the waters off Baja California Norte by midweek,
supporting combined seas as high as 9 ft. Fresh SW to W gap winds
will develop across the northern Gulf of California Tue and Wed.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh winds are found across the Gulf of Papagayo . Gentle to
moderate winds prevail between Colombia and the Galapagos
Islands. Light to gentle winds are elsewhere across the
discussion waters. Seas are 5-7 ft in S swell between Colombia
and the Galapagos Islands, and 4-6 ft elsewhere.
For the forecast, fresh gap winds will pulse across the Papagayo
region through Tue, with moderate winds thereafter. Gentle to
moderate winds will prevail between Colombia and the Galapagos
Islands. Light to gentle winds are expected elsewhere. Moderate
seas will prevail through Thu. Large SW swell will enter the
waters south of the Equator Fri, bringing rough seas to the
waters between the Galapagos Islands and Colombia.
...REMAINDER OF THE AREA...
A broad surface ridge extends across the waters north of 20N.
The pressure gradient between this area of high pressure and
lower pressure in the vicinity of the ITCZ is supporting moderate
to fresh NE trade winds north of the ITCZ to 20N and west of
115W, where seas are 6 to 8 ft. Gentle to moderate winds are
elsewhere north of the ITCZ. Gentle to moderate SE winds are
found south of the ITCZ. Seas over these waters are in the 5-7 ft
range in mixed SW and N to NE swell.
For the forecast, little change is expected in winds the next
few days. Large NW to N swell generated by a deep low well N of
the area will enter waters north of 27N by midweek, with wave
heights in excess of 8 ft spreading as far south as 20N by Fri,
then subsiding. The combination of wind waves developing from
fresh to locally strong trades N of the ITCZ and W of 120W, and a
mix of N and S swell, will bring rough seas over these waters.
