.SYNOPSIS...
High pressure will hold over the waters through tonight. An area
of low pressure may develop and move west across the waters Monday
and Tuesday and then well west of the area by midweek. This will
bring increasing shower and thunderstorm activity for much of the
upcoming week. Winds and seas are expected to remain below
cautionary levels at this time, but gusty winds and locally rough
seas will occur in the vicinity of thunderstorms.
