The low will shift toward South Florida by late tonight while the cold front slowly moves eastward, stalling and weakening by mid-week. Fresh to strong N winds are expected elsewhere behind the front through this evening. Scattered showers and thunderstorms are expected with the low and front. Looking ahead, a stronger cold front is expected to move off the Texas coast Thu evening followed by near-gale to gale force winds and rough to very rough seas across the basin through Fri night, with strong gales possible off Veracruz. $$ GMZ040-210230- NW Gulf including Stetson Bank- 921 AM EST Tue Dec 20 2022 ...GALE CONDITIONS POSSIBLE THU NIGHT AND FRI... .TODAY...N winds 20 kt in the afternoon.
