Individual waves may be more than twice the significant wave height. GMZ001-201430- Synopsis for the Gulf of Mexico 928 PM EST Thu Dec 19 2019 .SYNOPSIS...The tight gradient in place from strong high pressure well north of the area is allowing for strong north to northeast to east winds over much of the eastern Gulf and Straits of Florida. These winds will continue through Fri as a north to south aligned surface trough develops over the central Gulf. Strong east winds will occur to the east of this trough through late Fri night as low pressure begins to develop along the trough over or near the north-central Gulf by early on Sat and move northeastward to the NE Gulf while deepening during the rest of Sat and through Sun evening before it moves inland the Florida panhandle Sun. A cold front trailing from this low will sweep across the central and eastern Gulf Sat through Sun night followed by strong west to northwest winds. These winds will diminish early next week as high pressure settles in over the NW Gulf. $$ GMZ011-201430- NW Gulf including Stetson Bank- 928 PM EST Thu Dec 19 2019 .OVERNIGHT...E winds 10 to 15 kt.
