Caution levels for the offshore waters late tonight and Saturday
morning. A strong cold front will approach early Monday with
strengthening southwest winds expected. The cold front will cross
our region late Monday afternoon and evening. Northwest winds will
strengthen in the wake of this frontal passage for much of next

high pressure builds eastward along the northern Gulf coast. High
pressure will then gradually weaken as it shifts towards our area by
New Year's Eve, allowing winds and seas to gradually subside.
