The cold front will progress farther southeastward across central Florida tonight, then stall over southern Florida and southeastern Gulf Tue. The entire frontal boundary should gradually weaken and dissipate Tue evening. Moderate N to NE winds are expected north of the front. High pressure will build over the basin in the wake of this front, leading to gentle to moderate winds and slight seas over the Gulf through Thu. Afterward, winds across the eastern Gulf might increase due to increasing gradient. $$ Expires:202510210945;;474761 FZNT24 KNHC 202140 OFFNT4 Offshore Waters Forecast for the Gulf of America NWS National Hurricane Center Miami, FL 540 PM EDT Mon Oct 20 2025 Offshore Waters Forecast for the Gulf of America Seas given as significant wave height, which is the average height of the highest 1/3 of the waves.
