imagery, weather observations, radar and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
2300 UTC.

...SPECIAL FEATURES...

Western Atlantic Gale Warning: A frontal boundary extends from
31N70W to SE Florida. This front will drift southeastward tonight,
then stall from near Bermuda to the Straits of Florida through 
the rest of the week. A low pressure will track NE along the 
boundary from SE Florida to near Bermuda on Thu. The pressure 
gradient between strong high pressure to the north of the 
forecast area and the front is currently supporting NE gales 
offshore NE Florida. These gale force winds will spread eastward 
to about 72W, mainly north of 28N, through Wed night, before 
gradually ending as the low pressure moves north of the area. 
Very rough seas of 15 to 20 ft will be generated by these gales, 
and rough seas in N swell will impact a much larger area through 
the end of the week. The front is likely to linger over the basin
into the weekend, so marine conditions could be slow to improve.

East Atlantic Large Swell: Long period NW to N swell behind a 
cold front that extends across the eastern and central Atlantic 
is creating seas of 11 to 13 ft north of 25N and east of 40W. 
This swell event will continue to propagate southward with seas 
8 ft or greater reaching as far south as 10N on Wed. By late 
Thursday afternoon, the swell should decline enough to allow seas
to drop below 12 ft. 

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

Gale Warning E of 35W: Meteo-France has issued a Gale Warning for
the forecast zone of Madeira. The forecast calls for NW gales to
40 kt, with severe gusts from 08/12 UTC to 09/00 UTC at least.
Very rough seas in NW swell are also reaching the islands.

listed on their website https://wwmiws.wmo.int

...MONSOON TROUGH/ITCZ...

The monsoon trough stays mostly over Africa. The ITCZ extends 
west-southwestward from 03N12W to 00N30W to NE Brazil near 01S50W.
Scattered moderate to isolated strong convection is S of 05N 
between 10W and 30W. 

...GULF OF AMERICA...

A stationary front extends southwestward from SW Florida to a weak
1012 mb low pressure located just N of the Yucatan Peninsula. 
Scattered showers and isolated thunderstorms are over the SE 
Gulf. Fresh to strong NE winds and rough seas are N of the front 
and E of 90W. Gentle to moderate winds and moderate seas are 
elsewhere N and W of the front. Light to gentle SW to W winds 
and slight to moderate seas are noted ahead of the front, including
the Straits of Florida. 

For the forecast, strong to locally near gale NE winds, rough seas,
and scattered showers will continue in the E Gulf through Thu, as
the frontal boundary stalls near the Florida Straits. Conditions
will gradually improve Fri into the weekend as high pressure builds
southwestward across the northern Gulf. 

...CARIBBEAN SEA...

The Atlantic ridge extends SW reaching the NE Caribbean. This
system is supporting moderate to fresh E to SE winds and seas of
5 to 7 ft across the eastern part of the basin. Gentle to moderate
NE to E winds and 3 to 5 ft seas exist across the central Caribbean
while light and variable winds and seas of 1 to 3 ft dominate the 
NW Caribbean. Scattered showers with embedded thunderstorms are
seen over the Greater Antilles. Low-topped trade wind showers are
noted elsewhere. 

For the forecast, fresh to strong trades will prevail over the 
east and central Caribbean through Thu, with gentle to moderate 
winds to the west. Strong high pressure will then build southward
from the western Atlantic, with a tightening pressure gradient 
leading to increasing winds, especially in the south-central
portion of the basin. 

...ATLANTIC OCEAN...

A Gale Warning is in effect for the western Atlantic. Please refer
to the Special Features section for more details. 

A frontal boundary extends from 31N75W to SE Florida. Scattered 
to numerous showers and thunderstorms are near the front affecting
mainly the waters from 24N to 30N W of 65W. Strong to gale force
winds are NW of the front while moderate to fresh E to SE winds 
are ahead of the front based on scatterometer data. Farther E, a
cold front crosses just E of the Canary Islands and continues 
westward to near 24N30W where it begins to dissipate. Mainly low 
clouds, with possible showers, are associated with this front. 
The remainder of the Atlantic forecast area is under the influence
of a ridge, anchored by a 1037 mb high pressure located SW of 
the Azores near 36N34W. This system is supporting fresh to strong
winds E of 60W, including the tropical Atlantic. Rough to very 
rough seas in NW to N swell are observed per altimeter data N of 
16N and E of 50W. Elsewhere, moderate or weaker winds and
moderate seas are observed.

For the forecast west of 55W, please refer to the Special Features
section for all the information related to the above mentioned
frontal boundary.
