507 FZNT32 KNHC 231425 OFFN21 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 925 AM EST Sun Nov 23 2025 Marine Weather HF Voice Broadcast for the Gulf of America 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. .SYNOPSIS...A weak stationary frontal boundary extending from the western Florida Panhandle to South Texas will lift northeastward as a warm front later today as low pressure develops near the Texas and Oklahoma panhandles. Expect fresh southerly flow off the Texas coast tonight through Mon night supported by the gradient between low pressure over northeast Mexico and high pressure off the Carolinas. These winds will diminish Tue ahead of a frontal boundary that will be nearing the Texas coast. A stronger reinforcing cold front will overtake the frontal boundary early Wed while emerging out over the northwest Gulf. The cold front will then sweep to the southeast of the basin by late Thu, followed by fresh to strong northeast winds and building seas. Scattered showers and thunderstorms may accompany the initial frontal boundary. Gulf of America N of 26N W of 87W .TODAY...NE winds less than 10 kt.
