A broad area of low pressure over the southwestern Gulf of
Mexico will bring unsettled weather to the Gulf waters through
much of this week. Look for increasing winds, seas, and water
levels across the upper Texas coastal waters over the next few
days. Small Craft Advisory conditions are expected to begin today
and last through much of the week. The chance of gale force winds,
at least in gusts, is increasing for the Tuesday to Wednesday time
frame. Mariners should closely monitor the forecasts.
