.SYNOPSIS...

Light offshore winds will turn onshore again this morning as high
pressure begins ridging across the northeast GoM, washing
northward the boundary previous placed over coastal waters. A
series of weak easterly waves moving from south to north into
south Louisiana will bring about scattered to numerous showers and
thunderstorms today and Wednesday. Weakness aloft is established
Thursday and beyond allowing for the return of normal diurnally
driven showers and thunderstorms.

Fairly light southerly flow and low seas will prevail until the
weekend.
