High pressure will start to become more dominant over the waters
today and Tuesday, allowing easterly to southeasterly winds to relax
a bit to between 10 and 15 knots. Seas will also decrease to 2 to
4 feet as the winds relax. This brief respite in rougher conditions
will end on Wednesday as another low in the Gulf develops and

to near advisory levels in the offshore waters and seas will
increase to 4 to 6 feet from Wednesday through Friday.
