GMZ001-210915- Synopsis for the Gulf of Mexico 501 PM EDT Sat Oct 20 2018 .SYNOPSIS...A cold front extends from 30N92W to a 1016 mb low at 27N96W. A trough exetnds from the low to 23N96W and to near 19N95W. The cold front will push into the northern Gulf tonight, and sweep across the eastern and central Gulf waters tonight and become stationary from S Florida to 26N93W and warm front to a new 1017 mb low at 26N97W on Mon. A cold front will extend from the new low to 24N96W, and stationary to Mexico near Tampico. The present 1017 mb low over the NW Gulf will dissipate late tonight over the north-central Gulf. The new Low will lift north- northeastward through Mon night, then east-northeastward across the north-central Gulf through Wed night and the NE Gulf Thu, with a front to trail from it to the SW Gulf, and another front from the low eastward across N-central Florida. High pressure will build across the southeastern United States to the waters north of the low and front, and also behind the trailing front. The ensuing gradient will support fresh to strong NE to E winds and building seas over the waters north of the low and front east of 93W, and fresh to strong NW winds over the far western waters west of the trailing front. $$ GMZ011-210915- NW Gulf including Stetson Bank- 501 PM EDT Sat Oct 20 2018 .TONIGHT...NE to E winds 10 to 15 kt, becoming NE 20 to 25 kt late.
