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
2200 UTC.
...TROPICAL WAVES...
An central Atlantic tropical wave is near 37W from 11N southward,
and moving westward at 5 to 10 kt. No significant convection is
evident at this time.
An central Caribbean tropical wave is near 68W 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 numerous
moderate to strong thunderstorms 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 continue to sustain
gentle to moderate E to SE winds through Thu. The exception will
evening pulses of fresh winds off the northern Yucatan. An upper-
level trough across the western Gulf should continue to couple
with abundant tropical moisture to produce 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, other than the aforementioned thunderstorms south of
the Mona Passage near the tropical wave, 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
altogether 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 7-10 ft in the central Caribbean, and 4-7 ft
elsewhere.
For the forecast, the tight pressure gradient between high
pressure in the western Atlantic and the Colombian low will
continue to support fresh to strong trades over the south-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 will reach fresh to strong each evening through the
same period. Fresh to strong trades and rough seas will expand
northward into the north- central basin this evening, then
gradually subside Thu.
...ATLANTIC OCEAN...
A cold front curves southwestward from west of the Azores across
31N38W to 26N55W, then turn northwestward to 30N63W. Fresh to
strong NE winds and 7 to 9 ft seas are present near and behind the
aforementioned cold front. Farther south, fresh to strong SE winds
and 7-9 ft seas are active from 15N to 27N and west of 55W into
the southern and 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 are anticipated 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. A cold front
from 25N55W to 25N60W 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 0000 UTC surface analysis and satellite imagery through
0200 UTC.
...TROPICAL WAVES...
The axis of a tropical wave is near 87W 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 10N127W to 08N140W. Scattered moderate
to isolated strong convection is noted from 03N to 10N east of
98W, and from 02N 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. Light to gentle winds prevail elsewhere. Seas are in
the 4-6 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
110W, 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.
