239 FZNT25 KNHC 182126 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 426 PM EST Sat Jan 18 2025 ...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 has moved into the NW Gulf today and extends from central Louisiana to along the Texas-Mexico border. Northerly winds behind the front will gradually increase tonight, becoming strong by early Sun as the front reaches from the Florida Big Bend to near Veracruz, Mexico. Strong high pressure over the central U.S. will build across the basin behind the progressing front on Sun to produce a brief period of gale force winds Sun afternoon in the western Gulf waters offshore of Tampico and Veracruz. The front is expected to stall across the Yucatan Channel and Straits of Florida on Mon and gradually dissipate through Tue. Low pressure is expected to form over the NW Gulf on Mon night, then track southeastward through Wed, dragging a strong cold front across the entire basin. Strong high pressure behind the front will induce gale force N to NE winds expanding across much of the northern and western Gulf Tue and Tue night, with the potential for gusts to storm force across central portions. Mariners are urged to exercise extreme caution across the basin, due to the expansive area of gale force winds and large area of seas 15 to 20 ft expected to accompany this next frontal system. ...DENSE FOG ADVISORY... .TONIGHT...S to SW winds 15 to 20 kt.
