including Galveston and Matagorda Bays.

A broad area of low pressure is forecast to form over the
southwestern Gulf of Mexico in a day or two...moving slowly
westward or west-northwestward. In addition to periods of
unsettled weather, look for increasing winds, seas, and water
levels across the upper Texas coastal waters as we head into the
early and midweek time period. Small craft advisories are likely
and some gale conditions cannot be ruled out in the Gulf waters.
Mariners should closely monitor the forecasts.
