000 FZNT32 KNHC 281952 OFFN21 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 252 PM EST Tue Dec 28 2021 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 ridge extending from the western Atlantic into the Gulf will support moderate to fresh winds across the central and western Gulf through Wed night. The ridge will shift eastward, allowing for gentle to moderate winds and slight to moderate seas across the entire basin Thu as a weak frontal boundary stalls and dissipates along the Texas coast. Looking ahead, southeast to south winds are expected to increase over the western Gulf by late Fri as low pressure moves into the Central Plains. A strong cold front associated with this low pressure may reach the Texas coast late Sat night or early Sun before it quickly moves to the eastern Gulf late Sun. Gale-force winds are possible behind the front over the western Gulf from early Sun through Mon night, with strong to near gale-force winds elsewhere across the area in the wake of the front. Seas are expected to quickly build behind the front as well. Gulf of Mexico N of 26N W of 87W ...GALE CONDITIONS POSSIBLE W OF 94W SUN... .TONIGHT...S winds 10 to 20 kt.
