605 FZNT32 KNHC 160255 OFFN21 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1055 PM EDT Tue Jul 15 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...Weak high pressure now centered across the NW Gulf extends a narrow ridge southeastward to the Yucatan Channel, and will meander about the NW Gulf through late Thu. A weak 1012 mb low pressure, Invest AL93, is inland across north Florida near 30N82.5W, and is forecast to move westward, and could emerge over the waters of the far northeastern and north-central Gulf, possibly approaching the coast of Louisiana on Thursday. Environmental conditions over the Gulf appear generally favorable for additional development, and a tropical depression could form if the system moves far enough offshore over the next couple of days. Regardless, scattered to numerous showers and thunderstorms, some with strong gusty winds and locally rough seas, will accompany this system.
