.SYNOPSIS...

Small Craft Advisory is in effect for the Gulf waters due to
breezy north winds and building seas in wake of the passage of a
cold front. Showers and thunderstorms will be possible along and
behind the front through Monday but will be most numerous through
the evening hours. Onshore flow will begin to develop by Monday
night as high pressure begins moving eastward. Onshore flow will
then increase by Wednesday into Thursday as the overall pressure
