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.
...SPECIAL FEATURES...
Gulf of America Gale Warning: A cold front has stalled tonight
across the southern Gulf, from the Straits of Florida to near
22N90W to the central Bay of Campeche and into the coast of
Mexico near 93W. Satellite imagery suggests that the portion of
the front W of 90W has been drifting westward in recent hours.
1026 mb high pressure has moved into far NE Mexico, while 1035 mb
high pressure is across the NE U.S. extending a ridge southward
across the basin. The pressure gradient south of these highs is
forcing gale-force NW to N winds and very rough seas of 14-20 ft
across the SW waters of the Gulf, S of 21N between the front and
the Mexican coastline, while fresh to strong E-NE to NE winds and
seas of 8 to 12 ft prevail across most of the remainder of the
basin N of the front. The front will remain generally stationary
and weaken into Tue. Gale winds and very rough seas to 15 ft will
prevail in the SW basin through sunrise, then slowly diminish
through Tue night.
Atlantic Gale Warning: The aforementioned cold front is eastward
across the Atlantic waters N of 27N, and extends through 31N71.5W
to 27N73W then becomes nearly stationary through the NW Bahamas
and into the Straits of Florida. W of the cold front, N-NE to NE
winds of 20 to 30 kt prevail, with winds near gale-force and
frequent gusts to 40 kt N of 29N and W of 73W, where a Gale
Warning is in effect. Very rough seas of 12 to 16 ft prevail
across these waters. The front is associated with a deep low
pressure system across the western Atlantic currently near 32N71W.
The low is expected to lift northward overnight, which will slow
the forward progress of the front. Winds west of the front are
expected to gradually diminish later tonight, with gales ending by
morning.

Hurricane Center under AWIPS/WMO headers FZNT02 KNHC/HSFAT2 or at
website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for further
details.
...MONSOON TROUGH/ITCZ...
The monsoon trough extends across western Africa to the coast of
Guiea-Bissau near 12N16W and extends about 60 nm to the southwest.
The ITCZ extends from 07N21W to 06N36W to 09.5N45W to the coast of
Guyana near 06.5N58W. Scattered to locally numerous moderate
isolated strong convection is occurring from 09N to 16.5N between
35W and 52W.
...GULF OF AMERICA...
See the Special Features section above for information on the Gale
Warning in effect for portions of the southwest basin. Outside
of the gales, recent satellite scatterometer data shows strong
E-NE winds 20-28 kt E of 92W, and fresh to strong NE to N winds W
of 92W and N of 21N. Seas of 8 to 12 ft prevail across most of
the basin
