308 FZNT24 KNHC 202056 OFFNT4 Offshore Waters Forecast for the Gulf of Mexico NWS National Hurricane Center Miami, FL 356 PM EST Mon Jan 20 2025 Offshore Waters Forecast for the Gulf of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. GMZ001-210900- Synopsis for the Gulf of Mexico 356 PM EST Mon Jan 20 2025 .SYNOPSIS...The tail of a cold front extends across the Straits of Florida to W Cuba to the Yucatan Channel. The front will stall this evening and dissipate late tonight into Tue. Low pressure will form over the NW Gulf tonight, 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 tonight into early Tue, likely becoming strong gales and expanding across much of the northern and western Gulf Tue afternoon through early Wed, with the potential for gusts to storm force across portions of the west and central Gulf. The front is forecast to exit the basin by Wed morning with winds diminishing in the afternoon hours. Mariners are urged to exercise extreme caution across the basin due to the expansive area of gale-force winds and a large area of very rough to high seas that is expected to accompany this next frontal system. Looking ahead, a surface trough is forecast to develop along the E Mexican offshore waters by Thu evening with strong winds possibly reaching gale-force by Fri morning. Gales off Veracruz will diminish by Fri evening. $$ GMZ040-210900- NW Gulf including Stetson Bank- 356 PM EST Mon Jan 20 2025 ...GALE WARNING... .TONIGHT...NE to E winds 20 to 35 kt.
