000 FZNT25 KNHC 212122 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 522 PM EDT Sun Oct 21 2018 ...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...A cold front extends from Fort Myers Florida to 27N94W where it becomes a warm front to a weak 1016 mb low over the NW Gulf near 26N96W. A stationary front then trails from the low to 24N96W to 21N97W. A tight gradient between the fronts and strong high pressure over the central United States that is building east-southeastward over the southeastern United States is allowing for strong NE winds over the northern half of the basin W of 89W, and fresh N to NE winds E of 89W. The cold front will continue to move quickly across the Gulf E of 96W through tonight and become stationary over the SE Gulf on Mon. The low will slowly move northeastward through Mon night, then east northeastward across the N central waters through Thu night and the NE Gulf by Fri, dragging a new cold front across the SW Gulf. The tight gradient will gradually slackens allowing for the fresh to strong winds to slightly diminish Mon through early Tue. These winds are expected to increase again again late Tue or Wed as another low pressure forms over the NW Gulf and tracks northeastward toward northern Florida. .TONIGHT...NE to E winds 15 to 20 kt. Seas 3 to 5 ft. .MON...E winds 15 to 20 kt. Seas 3 to 5 ft. Isolated showers .MON NIGHT...E winds 10 to 15 kt. Seas 3 to 4 ft. .TUE...E winds 10 to 15 kt.

Within 200 nm east of the coast of Florida .SYNOPSIS...A strong cold front extending from 31N69W to West Palm Beach Florida will reach from near Bermuda to Miami tonight, and from near 28N65W to the Florida Keys Mon morning and become stationary through the middle of next week. Fresh to strong winds and building seas are expected behind this front through Mon night as strong high pressure slides eastward off the U.S. east coast. The high pressure and front will weaken Tue through early Thu allowing for winds to diminish and seas to subside. The gradient is forecast to tighten beginning on Thu east of NE Florida between high pressure to the N across the eastern seaboard and low pressure that tracks northeastward from the Gulf of the Mexico to across northern Florida. .TONIGHT...NE winds 15 to 20 kt.
