...SPECIAL FEATURES...

East Atlantic Significant Swell Event: 1004 mb low pressure is
located over the far eastern Atlantic between Madeira and the
Canary Islands. Large NW swell has been moving through the eastern
North Atlantic over the past several days. Seas of 12 to 15 ft
continue north of 25N and between 20W and 30W, being generated by
a gale- producing low pressure NE of the region. These very rough
seas will persist through early today, before subsiding as the
low pressure weakens.

Please refer to the latest NWS High Seas Forecast issued by the
National Hurricane Center, at website:
https://www.nhc.noaa.gov/ for more details.

...MONSOON TROUGH/INTERTROPICAL CONVERGENCE ZONE...

The monsoon trough extends from Guinea-Bissau to 04N20W, where it
transitions to the ITCZ and extends to 03N35W and then to the
coast of Brazil near 02S43W. Scattered showers and thunderstorms
are active from 01N-06N between 15W-27W.

...GULF OF MEXICO...

A 1022 mb high is centered at 27N90W, providing light to gentle
winds over the Gulf overnight. Seas are 1-4 ft. No deep convection
is occurring.

For the forecast, tranquil weather will prevail through Fri
morning. A relatively weak cold front will move through the E Gulf
Thu night through Sat. Fresh to strong NW to N winds will follow
the front over the NE Gulf Fri night into Sat before diminishing.
High pressure will build in the wake of the front with moderate to
fresh S return flow developing over the W Gulf Sun and Mon.

...CARIBBEAN SEA...

A stationary front extends from E Cuba to Honduras with N winds
moderate to fresh behind the front. A moderate pressure gradient
between the Bermuda-Azores High well northeast of the basin to a
1009 mb Colombian Low is forcing fresh to strong trades over the
south-central Caribbeans. Elsewhere, winds are gentle to moderate.
Seas are 4-7 ft over the NW Caribbean, 4-6 ft over the south-
central Caribbean, and 2-4 ft elsewhere. The Mona and Anegada
Passages are experiencing 5-6 ft N swells. Scattered showers are
occurring within 60 NM of the front.

For the forecast, the stationary front will dissipate later
today. The remnants of the front will strengthen winds off
Nicaragua Fri and continue through the weekend before diminishing
on Mon. Elsewhere, fresh to locally strong trades will prevail in
the south-central Caribbean into the weekend before strengthening
early next week. Rough seas in N swell over the Atlantic waters
east of the Lesser Antilles will subside later today.

...ATLANTIC OCEAN...

Please refer to the Special Features section for details
regarding a large swell in the eastern subtropical Atlantic.

A stationary front extends from just west of Bermuda to E Cuba,
with a weak 1014 mb low along the front near 28N74W. Winds are near
gale NE associated with the low north of 28N between 74W-78W with
seas currently at 12-14 ft. Buoy 41010 near 29N74.5W reported
seas of 14-16 ft overnight. Scattered showers are occurring north
of 23N between 67W-75W. Farther east, a broad 1004 mb low near
36N15W is producing a large area of fresh to strong NW to N winds
north of 25N east of 30W and the aforementioned area of large N
swell. Elsewhere, a moderate pressure gradient between a 1030 mb
Bermuda-Azores High at 34N44W to lower pressure within the ITCZ
is forcing moderate to fresh trades south of 20N with seas 8-10 ft
in mixed wind waves and N swell.

For the forecast west of 55W, the near gale NE winds associated
with the low north of 28N between 74W-78W will steadily diminish
today. The low will gradually weaken through the end of the week,
with conditions improving. A new cold front will move off the
coast of Florida late Fri. The front will progress across the
forecast waters, followed by fresh to strong W to NW winds north
of 29N Sat into Mon. High pressure will build in the wake of the
front by early next week. Rough seas in N swell over the Atlantic
waters east of the Lesser Antilles will subside later today.
