660 FZNT32 KNHC 212056 OFFN21 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 456 PM EDT Fri Jun 21 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 for the Gulf of Mexico .SYNOPSIS...A tight pressure gradient between the E Pacific monsoonal flow and surface ridging across the northern Gulf of Mexico is supporting fresh to near gale-force E to NE winds and rough seas in the Bay of Campeche and moderate to fresh E winds elsewhere. Winds over the SW basin are forecast to remain near gale-force as a broad area of low pressure is expected to form over the Bay of Campeche by this evening, thus increasing the pressure gradient further. Environmental conditions appear conducive for gradual development of this system as it moves slowly west-northwestward or northwestward, and a tropical depression could form over the southwestern Gulf of Mexico this weekend. Winds E of 90W are forecast to diminish to gentle to moderate speeds Sat night and to light to gentle speeds on Sun. Conditions are forecast to improve W of 90W Sun night into Mon.
