nautical miles including Galveston and Matagorda Bays
1032 PM CDT Fri Sep 18 2020

SYNOPSIS FOR HIGH ISLAND TO MATAGORDA SHIP CHANNEL OUT 60 NM

A moderate to occasionally strong northeast flow is expected
tonight. Conditions will deteriorate this weekend into next week
as Tropical Storm Beta moves closer to the Texas coast. This will
result in strong northeast to east winds, building seas and rising
water levels over the weekend and into the first half of next
week. Hazardous conditions are expected during this period. The
tropical storm is currently forecast to strengthen and become a
hurricane, approach the mid Texas coast later in the weekend,
then make a turn toward the upper Texas coast toward mid week.
Uncertainty exists, so mariners should monitor closely the
forecast for the latest updates.
