171 FZNT32 KNHC 191424 OFFN21 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1024 AM EDT Thu Sep 19 2024 Marine Weather HF Voice Broadcast 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. .SYNOPSIS...Weak surface ridging over the Gulf waters will support gentle to locally moderate easterly winds and slight seas through the upcoming weekend. Moderate winds may pulse in the eastern Bay of Campeche nightly through the next several days. A cold front is forecast to clip the far NE waters today into Fri with little change in winds and seas. Looking ahead, a broad area of low pressure could form early next week over the western and NW Caribbean Sea. Thereafter, gradual development of this system is possible, and a tropical depression could form as the system moves slowly to the N or NW over the NW Caribbean Sea and into the SE Gulf of Mexico through the middle part of next week. Regardless of development, winds and seas will start increasing across the SE Gulf by late Mon. Gulf of Mexico N of 26N W of 87W .THIS AFTERNOON...Variable winds less than 10 kt.
