000 FZNT25 KNHC 151935 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 235 PM EST Fri Dec 15 2023 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... Southeast Gulf of Mexico .SYNOPSIS...Strong high pressure building across the eastern United States will support strong winds over the northern and eastern Gulf of Mexico into tonight, with easterly gales offshore Florida. Low pressure will form in the SW Gulf tonight, then move NE Sat and inland across the Florida Big Bend Sat night. This will produce additional gales in the NE Gulf beginning Sat. Thunderstorms in association with this low will provide locally even higher winds and seas Sat and Sat night. A cold front will trail from the low, exiting the Gulf Sun morning. High pressure will then settle in over the area through early next week allowing for marine conditions to improve. ...GALE WARNING THROUGH SAT NIGHT... .TONIGHT...E winds 25 to 35 kt.

Within 200 nm east of the coast of Florida .SYNOPSIS...A slow moving cold front extends from 31N50W to near 24N70W, where it becomes stationary and continues through the Straits of Florida. This front will sink southward before becoming fully stationary along 23N by Sat. The pressure gradient between the strong high pressure building north of the area and the front will result in near gale to gale force northeast to east winds and high seas over the waters W of 70W and north of 24N through this evening. The front will then gradually dissipate Sat night through Sun, in advance of Gulf of Mexico low pressure that will move NE across Florida Sat night. This low will move through the NW Atlantic waters Sun, when a large area of southerly gales will exist SE of the low. Thunderstorms in association with this low will provide locally even higher winds and seas this weekend. ...GALE WARNING THROUGH SAT NIGHT... .TONIGHT...E winds 25 to 35 kt.
