Synopsis for Jupiter Inlet to Ocean Reef FL out to 60 nm and for East
Cape Sable to Bonita Beach FL out to 60 nm-

.SYNOPSIS...High pressure will continue to allow for an easterly
flow across the Atlantic and Gulf coast waters tonight and
through the early portion of this week. Wave heights will range
from 1 to 2 feet during this time frame. On Tuesday, a cold front
will push into the local waters during the afternoon and evening
hours. As this occurs, the chance of showers will increase and
they will continue to be possible through the remainder of the
week as the front stalls out just south of the area. High
pressure will build in behind the front creating windy conditions
for the later portion of the week.
