...SPECIAL FEATURES...

Tropical Storm Nicole is centered near 29.4N 83.2W at 10/2100
UTC or 80 nm SE of Tallahassee Florida moving NW at 13 kt.
Estimated minimum central pressure is 990 mb. Maximum sustained
wind speed is 40 kt with gusts to 50 kt. The rainbands of Nicole
continue to generate scattered heavy showers across the NE Gulf of
Mexico where peak seas are 12 ft. On the forecast track, the
center of Nicole will move along the coast of the Florida Big Bend
region for the next several hours before moving across the
eastern Florida Panhandle. After that, Nicole should move
northward over Georgia later tonight, and then move through the
southeastern United States on Friday. Little change in strength
is expected this evening while the center moves along the coast of
the Florida Big Bend. Nicole is expected to weaken to a depression
over Georgia tonight, and then it is expected to dissipate as it
merges with a frontal boundary over the Mid-Atlantic United States
by Friday night. Please read the latest NHC Public Advisory at
https://www.nhc.noaa.gov/text/MIATCPAT2.shtml and Forecast/
Advisory at https://www.nhc.noaa.gov/text/MIATCMAT2.shtml as well
as the High Seas Forecast issued by NHC at
www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.

Gulf of Mexico Gale Warning: A cold front is expected to emerge
off the Texas coast on Fri night and extends from Pensacola,
Florida to Veracruz, Mexico Sat afternoon. Fresh to near gale
force winds will follow this front, which will reach gale force
speed just N of Tampico Sat morning. These northerly winds will
reach the Veracruz offshore waters Sat afternoon/early evening.
Please read the latest the High Seas Forecast issued by NHC at
www.nhc.noaa.gov/text/MIAHSFAT2.shtml as well as the local NWS
Forecast offices Tallahassee, FL and Mobile, AL for more details.

...TROPICAL WAVES...

A tropical wave is in the E Caribbean with axis S of 19N and near
64W, moving west at around 5 kt. Isolated showers and
thunderstorms are observed throughout the eastern Caribbean E of
68W mainly affecting the Windward Islands.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of W Africa near 10N14W
to 06N19W. The ITCZ continues from 06N19W to 07N35W to 05N52W.
Scattered moderate convection is observed from 03N to 10N, between
17W and 37W. Scattered moderate convection is from 02N to 10N between
16W and 39W.

GULF OF MEXICO...

See Special Features section above for information on Tropical
Storm Nicole and an upcoming Gale Warning.

Tropical Storm Nicole near 29.4N 83.2W 990 mb at 4 PM EST moving
NW at 13 kt. Maximum sustained winds 40 kt gusts 50 kt. Strong to
near gale force winds in the SW semicircle of Nicole are affecting
the NE Gulf of Mexico offshore waters where seas are in the 8 to
12 ft range. Light to gentle variable winds are elsewhere in the
western half of the basin and in the SE gulf where seas are in the
3 to 5 ft range.

For the forecast, Nicole will move inland and weaken to a tropical
depression near 31.2N 84.2W Fri morning, inland to 34.9N 82.6W
Fri afternoon, and dissipate Sat morning. Strong winds and rough
seas are expected over the eastern Gulf through Fri morning.
Looking ahead, a cold front should move over the NW Gulf Fri
evening and stretch from SE Louisiana to NE Mexico by Sat morning,
and from Tampa Bay, FL to the western Bay of Campeche by Sun
morning. Strong to minimal gale force northerly winds are expected
in the wake of the front near the Tampico area by Sat afternoon
with seas building to 8 or 9 ft.

CARIBBEAN SEA...

The presence of Tropical Storm Nicole over NW Florida continue to
disrupt the Atlantic subtropical ridge, which typically governs
trade wind flow across the Caribbean. As a result winds are light
to gentle and variable across the western half of the Caribbean
with 1-3 ft seas. Moderate trade wind flow is across the eastern
half of the basin, being supported by the passage of a tropical
wave. Seas to 3 ft dominate this region.

For the forecast, as Nicole moves farther inland over the SE of
United States, winds will veer to the NE and E over the NW
Caribbean. Gentle to moderate winds will prevail elsewhere.

ATLANTIC OCEAN...

Please read the SPECIAL FEATURES section above for more on
Tropical Storm Nicole.

West of 72W, the subtropical Atlantic is dominated by the
circulation of Tropical Storm Nicole, described in detail in the
Special Features Section above.

A cold front extends from 31N31W to 28N48W where it becomes
stationary and continues to 30N72W. North of this boundary, winds
are fresh to strong from the E and SE with 8-14 ft seas,
higher closer to Nicole. South of the boundary, winds are gentle
to moderate from the E to SE with 4-8 ft seas.

For the forecast west of 55W, Tropical Storm Nicole near 29.4N
83.2W 990 mb at 4 PM EST moving NW at 13 kt. Maximum sustained
winds 40 kt gusts 50 kt. Nicole will move inland and weaken to a
tropical depression near 31.2N 84.2W Fri morning, inland to 34.9N
82.6W Fri afternoon, and dissipate Sat morning. Large seas of 12
ft or greater associated with Nicole and a frontal boundary that
extends roughly along 27N are forecast to gradually subside on
Fri, with seas below 12 ft by late Fri. Looking ahead, a cold
front will move off the coast of northeast Florida early Sun, then
weaken as it moves to a position from Bermuda to the Florida
Straits by Mon night.
