Tropical Weather Discussion for North America, Central America
Gulf of Mexico, 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 1200 UTC surface analysis and satellite imagery through
1610 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning: A tight pressure gradient between high
pressure north of the Caribbean Sea and lower pressure over
Colombia will support fresh to strong NE to E trades over the
central Caribbean through early next week. Winds near the coast
of NW Colombia will pulse to gale-force during the evening and
early morning through early next week. Seas are expected to peak
near 12 ft each morning.
Please read the latest High Seas Forecast at
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of
Senegal near 13N16W to 10N17W. The ITCZ is analyzed south of the
equator. Scattered moderate to isolated strong convection is
observed S of 06N and E of 20W.
GULF OF MEXICO...
Moderate to fresh E to SE winds prevail over the NW Gulf, where
seas range from 4 to 7 ft. Elsewhere, gentle to moderate E to SE
winds and seas of 2 to 4 ft prevail.
For the forecast, fresh SE winds over the NW Gulf will expand
eastward through Fri as high pressure builds over the
southeastern United States. Fresh to locally strong winds off
the Yucatan Peninsula will change little into early next week.
CARIBBEAN SEA...
Please read the Special Features section for details on a Gale
Warning in the south-central Caribbean Sea.
Aside from the gale-force winds off the coast of Colombia, fresh
to strong NE to E winds prevail over the south central
Caribbean. Moderate to fresh trades are elsewhere over the
Caribbean waters, except gentle to moderate in the lee of Cuba.
Seas are in the 7 to 11 ft range over the south central
Caribbean. Seas over the western Caribbean are in the 2 to 4 ft
range. Elsewhere, seas are in the 4 to 6 ft range.
For the forecast, the pressure gradient between high pressure N
of the area and low pressure over Colombia will support fresh to
strong trade winds over the central Caribbean through early next
week. Winds north of Colombia will pulse to gale-force each
night through Mon night. Winds will pulse to fresh to strong
across the approach to the Windward Passage Fri through Sat.
Moderate to fresh trade winds will prevail elsewhere across the
Caribbean. Seas will build to around 8 ft in the Tropical North
Atlantic this weekend.
ATLANTIC OCEAN...
A cold front extends from 31N59W to the central Bahamas.
Scattered moderate convection is observed on either side of the
front between 52W to 73W from 25N to 31N. Moderate to fresh S to
SW winds are found E of the front to 40W, and N of 27N. Moderate
to locally fresh NE winds are found from 20N to 30N and east of
30W. Gentle to moderate NE to E winds are elsewhere across the
discussion waters. Seas are in the 6 to 8 ft range in the region
of fresh winds N of 28N, and in the area of strong winds east of
30W. Seas are in the 2 to 4 ft range south of 25N and west of
65W, and 5 to 7 ft elsewhere.
In the forecast, the cold front will slowly move southeastward
through Fri, reaching along 22N/23N before it weakens and
dissipates Sat. High pressure building in the wake of the front
will tighten the pressure gradient, generating fresh to strong
northeast to east winds across the Bahamas starting tonight
before diminishing Sat. Fresh to strong southwest winds will
develop over the waters offshore northeastern Florida Fri night
in advance of the next cold front that will move off the coast
of the SE United States this weekend. This cold front is
expected to move southeast, becoming stationary from near 31N59W
to 26N73W by late Mon. The strong southwest winds are forecast
to lift north of the area Sun.
