Individual waves may be more than twice the significant wave height. GMZ001-171945- Synopsis for the Gulf of Mexico 331 AM EDT Thu Jun 17 2021 .SYNOPSIS...A broad area of low pressure in the Bay of Campeche will move little today, and little if any development is expected during that time due to interaction with land and unfavorable upper-level winds. However, the low should begin to move northward by this afternoon, and a tropical or subtropical depression is likely to form by late tonight or on Fri when the low moves across the western Gulf of Mexico. This area has a high chance of tropical cyclone formation during the next 48 hours. High pressure is forecast to build in across the basin in the wake of the low later in the upcoming weekend into early next week. $$ GMZ011-171945- NW Gulf including Stetson Bank- 331 AM EDT Thu Jun 17 2021 .TODAY...NE to E winds 10 to 15 kt.
