The Atlantic Tropical Weather Discussion provides current information on major weather patterns and disturbances in tropical regions. It assists decision-making by detailing significant weather features, expected trends, the reasoning behind forecasts, model performance, and sometimes the confidence level in predictions. The Discussion is issued four times daily: 1:05 AM EST, 7:05 AM EST, 1:05 PM EST and 7:05 PM EST.

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.

...SPECIAL FEATURES...

Post-Tropical Cyclone Gonzalo is centered near 19.3N 23.3W at
26/2100 UTC or 160 nm N of Sal Cabo Verde, moving NNW at 6 kt.
Estimated minimum central pressure is 1005 mb. Maximum sustained
wind speed is 35 kt with gusts to 45 kt.  Peak seas are near 18 
ft in the NE quadrant. Gonzalo is a sheared storm with numerous 
moderate isolated strong convection extending from 18N to 28N 
between 16.5W and 20.5W. On the forecast track, the center will 
continue to move away from northeastern portions of the Cabo Verde
Islands today. Additional weakening is forecast, and Gonzalo is 
expected to become a remnant low in the next 12-24 hours. Swells 
generated by Gonzalo are expected to affect portions of the Cabo 
Verde Islands through today before diminishing Sunday. These 
swells are likely to cause life- threatening surf and rip current 
conditions. Please consult products from your local weather 
office.

Please read the latest and Gonzalo NHC Forecast/Advisories and 
Public Advisories at www.hurricanes.gov for more details.

Very Large NE Swell: A cold front extends from near 31N68W 
through the Central Bahamas and into Cuba. Strong low pressure 
off the middle Atlantic coast of the U.S. has produce gale to 
storm force N to NE winds pointing toward Florida and the SE U.S. 
coast, and generating large swell. This swell is propagating into 
the area behind the cold front, producing seas of 8 to 12 ft 
generally to the N of 26W and W of 65W. Rough seas will follow the
front through later this afternoon, before starting to subside 
through Sun morning.

...TROPICAL WAVES...

A tropical wave is analyzed along 64W, south of 18N, moving west 
at near 10 kt.No significant convection is depicted at this time 
in association to this wave. 

A tropical wave is in the W Caribbean with axis along 82W, S of 
16N, extending across Panama, moving west at 10 kt. Convection
associated with this wave has moved well inland over Central
America. 

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 14N22W to 08N42W. The ITCZ 
extends from 08N41W to 11N61W. Aside from convection associated 
with Gonzalo, scattered moderate convection is noted from 04N to
14N between 22W and 40W, and from 10N to 15N between 49W and 60W. 

...GULF OF AMERICA...

A dissipating frontal boundary extends across the basin from the
western tip of Cuba to just offshore Tampico, Mexico. Scattered
moderate convection is within 30 nm of this boundary. Scattered
moderate convection is also being induced by a surface trough in
the central Bay of Campeche. Gentle or weaker winds and slights
seas prevail through the basin. 

For the forecast, light to gentle winds, and slight to moderate 
seas, will prevail through the weekend. Winds and seas will 
gradually increase from the early to the middle part of next week.

...CARIBBEAN SEA...

A weaker than usual pressure gradient across the nearby Atlantic
and Caribbean basin is translating to gentle to moderate trades 
over most of the basin. Seas are 2 ft or less in the NW and 3 to 
5 ft elsewhere. The eastern end of the Eastern Pacific monsoon 
trough is supporting a cluster of scattered showers and 
thunderstorms offshore of central and western Colombia. Scattered 
moderate convection is present across the waters between Jamaica 
and Cuba.

For the forecast, a weak pressure gradient will support moderate 
to fresh trades over the south-central Caribbean, and gentle to 
moderate winds elsewhere. Slight to moderate seas will be over the
NW Caribbean with moderate seas elsewhere. 

...ATLANTIC OCEAN...

See Special Features section above for information on Post-
Tropical Cyclone Gonzalo and on significant swell propagating 
southward into waters offshore Florida and NE of the Bahamas to 
65W.

Tropical Depression Fay is centered near 29.8N 43.9W at 26/2100
UTC or 970 nm WSW of the Azores, moving S at 2 kt. Estimated
minimum central pressure is 1009 mb. Maximum sustained wind
speed is 30 kt with gusts to 40 kt. Please read the latest HIGH
SEAS FORECAST issued by the National Hurricane Center at website
- https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and the latest
Fay NHC Forecast/Advisory and Public Advisory at
www.hurricanes.gov for more details.

A vigorous upper-level trough along the eastern seaboard of the
U.S. supports the deep low pressure off the middle Atlantic coast,
and a cold front across the western Atlantic waters from from
31N68W through the central Bahamas and into Cuba. Numerous strong
convection is ongoing E of this front, from NE Cuba through the
Turks and Caicos, then N of 23N between 65W 72W. 

Moderate to fresh SW winds are occurring N of 23N and ahead of 
the front to 62W, where seas are 5 to 7 ft in N swell. Behind the
front, moderate NW to N winds prevail. Seas are 8 to 12 ft in 
mostly N to NE swell. To the east, a surface trough supported by a
mid-level low is inducing numerous moderate convection from 24N 
to 30N between 54W and 62W. Moderate lo locally fresh winds and 
seas 4 to 6 ft are present in the vicinity of this trough. To the
SE, a belt of moderate trades prevails from 10N to 21N W of 40W 
to the Lesser Antilles, where seas are 5 to 6 ft. Farther E, 
moderate to fresh NE to E winds prevail S of the monsoon trough to
24N between 19W and 30W, where seas are 5 to 8 ft in NE swell 
from Gonzalo. Otherwise mainly gentle winds prevail. 

For the forecast west of 55W, the aforementioned cold front will 
reach from near Bermuda to central Cuba tonight before starting to
weaken. Scattered showers and isolated thunderstorms are expected
along the frontal boundary. Moderate to fresh winds are expected 
east of the front through the remainder of the weekend before 
diminishing. Rough seas behind the front will gradually subside 
through the remainder of the weekend.
