A broad area of low pressure over the southwestern Gulf of Mexico is expected to become a tropical storm as it tracks towards Mexico. Highs winds, hazardous seas, and above normal coastal water levels are likely well north of the center of the storm. With the exception of Galveston Bay, a Tropical Storm Warning is in effect over our coastal waters.
