...SPECIAL FEATURES...

Gales and Significant Swell N of Bahamas: A tight pressure 
gradient between a 1032 mb high pressure system over New England 
and a stationary front extending from S of Bermuda to a 1010 mb 
low just N of central Cuba is supporting fresh to near gale-force
NE winds and rough to very rough seas N of the front and W of the
low. Winds are reaching minimal gale force near 31N73W. Scattered
showers and isolated thunderstorms are noted N of the front 
between 65W and 75W. Winds will start to diminish tonight, with 
strong NE to E winds and rough to very rough seas persisting N of
28N and W of 65W through Thu night as the low pressure moves 
southwestward and the front weakens. Mariners are urged to remain 
alert to these dangerous marine conditions and take the necessary 
precautions to avoid these affected areas. 

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

...MONSOON TROUGH/ITCZ...

The monsoon trough reaches the Atlantic through the coast of
Africa near 12N16W and continues to 09N23W. The ITCZ extends from
09N23W to 09N60W. Scattered moderate to isolated strong 
convection is noted from 05N to 11N and between 29W and 59W.

...GULF OF AMERICA...

Moderate to fresh winds, and moderate seas prevail E of 90W. W of
90W, gentle to moderate winds and moderate seas are noted. 

For the forecast, a tight pressure gradient between high pressure
system over New England and a complex weather system over the Cay
Sal area of the Bahamas will continue to support fresh to strong 
NE to E winds and rough seas in the E Gulf into late this week. 
Winds and seas will gradually diminish into Sat as the ridge 
slides eastward. Looking ahead, another robust high pressure 
system will reach New England late this weekend and early next 
week allowing winds and seas to increase in the NE Gulf. 
Elsewhere, gentle to moderate winds and moderate seas will prevail
into early next week. Expect fresh SE to S winds over much of the
Gulf by Mon between high pressure over the western Atlantic and a
cold front moving through the Southern Plains. 

...CARIBBEAN SEA...

A weak pressure gradient is supporting gentle to moderate winds
and slight to moderate seas. 

For the forecast, a surface trough extends along 80W north of 15N
into central Cuba. The trough will drift westward and weaken over
the next couple of days. Ample tropical moisture and upper- level
divergence support scattered showers and isolated thunderstorms 
over the central Caribbean. Otherwise, moderate to locally fresh 
trade winds in the E Caribbean will continue over the next few 
days, gradually extending westward into the south- central 
Caribbean through the week and into the upcoming weekend. 

...ATLANTIC OCEAN...

Please see the Special Features section above for information on
a gale warning and significant swell causing very rough seas 
north of the Bahamas.

Aside from the conditions mentioned in the Special Features
section above, winds are moderate or weaker, with moderate seas.

For the forecast west of 55W, a tight pressure gradient between 
high pressure system over New England and a stationary front 
extending from SE of Bermuda to a 1010 mb low in the Cay Sal area 
of the Bahamas supports strong to gale-force NE winds and rough to
very rough seas north of the front. Scattered showers and 
isolated thunderstorms are occurring east of the Bahamas. Strong 
NE to E winds and rough to very rough seas will persist N of 28N 
and W of 65W through Thu night as the low pressure moves 
southwestward and the front weakens. Weak low pressure will 
develop southwest of Bermuda by Fri, then lift northeastward and 
reinforce the frontal boundary over the waters between the central
Bahamas and Bermuda. Expect fresh to strong NE-E winds and seas 
to 11 ft N of the front through early next week.
