...SPECIAL FEATURES...

Gales and Significant Swell N of Bahamas: A tight pressure 
gradient between a 1031 mb high pressure system over New England 
and a stationary front extending from S of Bermuda to a 1010 mb 
low just N of western 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. Winds 
will 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 14N17W and continues to 10N23W. The ITCZ extends from
10N23W to 07N58W. Scattered moderate to isolated strong 
convection is noted from 03N to 14N and E of 46W.

...GULF OF AMERICA...

A tight pressure gradient between a high pressure system over New
England and a stationary front over the offshores NE of the 
Bahamas support fresh to strong NE to E winds and rough seas in 
the E Gulf. W of 90W, gentle to moderate winds and moderate seas 
are noted.

For the forecast, fresh to strong NE to E winds and rough seas in
the E Gulf will prevail into late this week. Winds and seas will 
gradually diminish into Sat as the ridge slides eastward. 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. Looking ahead, 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, 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, the tight pressure gradient between
a high pressure system over New England and a stationary front 
extending across the offshore zones N of 27N to a 1010 mb low in 
the Florida Straits 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 across 
the offshores between 59W and 76W. Strong NE to E winds and rough 
to very rough seas will persist N of 27N and W of 65W through Thu 
night as the low pressure moves southwestward and the front 
weakens. Looking ahead, weak low pressure will develop southwest 
of Bermuda by Fri, then lift northeastward and reinforce the 
frontal boundary over the waters between the northern Bahamas and 
Bermuda. Expect fresh to strong NE-E winds and seas to 11 ft N of 
the front through early next week.
