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 1800 UTC surface analysis and satellite imagery through 
2350 UTC.

...SPECIAL FEATURE...

Caribbean Gale Warning: The pressure gradient between surface 
ridging in the SW N Atlantic waters associated with a high 
pressure of 1022 mb located SW of Bermuda near 30N68W and lower 
pressure in NW Colombia are supporting strong to near gale force
winds in the Gulf of Venezuela and Colombia adjacent waters. The
low pressure will briefly deepen this evening and tonight, which
will lead to the development of gale force winds within 60 nm of 
the coast of Colombia continuing through early Fri morning. Seas
of 8 ft are forecast to build to 11 ft during this period. 

Please read the latest High Seas Forecast issued by the National 
Hurricane Center at https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml 
for further details. 

...MONSOON TROUGH/ITCZ...

The monsoon trough exit the W coast of Africa and enters the 
Atlantic near 07N11W and continues to 02N19W. The ITCZ extends 
from 02N19W and continues along 01N35W to 00N50W. Scattered 
moderate to isolated strong convection is observed south of 06N 
and east of 19W and also south of 06N and between 32W and 43W.

...GULF OF MEXICO...

As of 2100 UTC, the remnants of a former cold front extends from 
the Florida Big Bend to 26N85W to 24N89W. A second surface trough
extends along coastal northern and central Florida with tail
reaching the Florida SW adjacent waters. Scattered showers are
across the SE gulf between Sarasota and the Florida Straits.
Otherwise, a weak pressure gradient is prevalent across the basin,
which is supporting mainly light to gentle variable wind across
the E and NW gulf where altimeter data show seas of 3 to 6 ft. In
the SW gulf W of 94W winds are moderate from the SE while in the
eastern half of the Bay of Campeche winds have the same speed but
are from the N to NE. 

For the forecast, the surface trough over the NE Gulf of Mexico 
will weaken through tonight. Winds and seas offshore the western 
Florida Panhandle and Alabama will continue to subside through 
early this evening. A cold front is forecast to enter the western 
Gulf Sat night and move across much of the Gulf, extending from 
Sarasota, FL to Tampico, Mexico by early Mon. Fresh to strong N to
NE winds and building seas are likely behind the front over much 
of the western and central Gulf Sun into early Mon. Well in 
advance of the front, there is a possibility of some severe 
thunderstorm squalls with gusty winds over portions of the north- 
central and NE Gulf late Sat afternoon through Sat night. 

...CARIBBEAN SEA...

See the Special Features Section above for details on a Gale
Warning for the south-central Caribbean waters. 

Shallow patches of moisture embedded in the trade wind flow are
supporting isolated showers in the E Gulf of Honduras and the SE
Caribbean. Surface ridging in the SW N Atlantic waters associated
with a high pressure of 1022 mb located SW of Bermuda near 30N68W
against lower pressure in NW Colombia are supporting moderate to
locally fresh trades in the E and great portions of the SW
Caribbean, except for strong to near gale force winds in the Gulf
of Venezuela and Colombia adjacent waters. Seas are 5 to 8 ft in
the central and SW Caribbean and 2 to 4 ft elsewhere. 

For the forecast, the Atlantic ridge, located just N of the NE 
Caribbean, will sustain a moderate trade-wind regime across the 
eastern and central Caribbean through the weekend, except for 
fresh to strong in the south-central Caribbean. Strong to minimal 
gale force winds are forecast tonight within 60 nm of the coast of
Colombia. Fresh to strong winds will pulse in the Gulf of 
Honduras Fri night and Sat night. Looking ahead, winds should 
diminish across the basin early next week as a weakening cold 
front approaches the Yucatan Channel.

...ATLANTIC OCEAN...

A cold front extends from 25N54W to 23N61W, then continues as a 
stationary front to 24N71W. A warm front extends from 26.5N74W to 
31N81.5W. The remaining SW N Atlantic waters are dominated by a surface 
ridge anchored by a high pressure of 1022 mb located SW of
Bermuda. This set up is supporting fresh NE to E winds S of 27N
and E of the Bahamas and fresh to locally strong SE winds off the
NE coast of Florida where seas are 8 to 9 ft. The remainder
central and E subtropical Atlantic is under the influence of the
Azores High which along lower pressures over NW Africa support
fresh to strong NE winds and seas to 9 ft between the Canary
Islands and the W African coast. 

For the forecast W of 55W, fresh to strong SE winds north of 28N 
and west of 76W will prevail through this evening. The cold front 
will drift SE through early Fri while weakening. The next cold 
front should move offshore northern Florida Sun night.
