.SYNOPSIS...Favorable conditions prevail this week as high
pressure over the Gulf continues to result in mainly gentle
southeasterly to southerly winds and slight seas, though moderate
winds are possible across the Laguna Madre each afternoon and
early evening hours. Due to some minor surface coastal troughing,
we could see a few showers or thunderstorms over the Gulf waters
through the week.
