60 nautical miles including Galveston and Matagorda Bays
209 PM CDT Tue Jun 18 2024

.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.

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. Small Craft Advisory remains
in effect for Galveston Bay, but some gusts above 35 knots are
possible at times. Water levels will be rising and would
anticipate some coastal flooding in the bays and along the
beaches. Higher winds are possible in thunderstorms. Small craft
should consider remaining in port until weather conditions start
improving later this week.
