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.

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 extends along 63W, from 07N to 19N, moving west at around 5 kt. Isolated showers and thunderstorms are observed throughout the eastern Caribbean near this wave. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Guinea-Bissau near 12N16W to 07N19W. The ITCZ continues from 07N19W to 07N43W, where the convergent flow is interrupted by a surface trough. The ITCZ resumes from 08N54W to 11N60W. Scattered moderate convection is observed from 03N to 10N, between 17W and 37W. Scattered moderate convection is also observed from 07N to 13N, between 54W and 61W. 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. $$ Ramos
