.SYNOPSIS...Generally favorable boating conditions prevail through
the weekend, as the Atlantic ridge axis strengthens over the local
waters. Light southerly flow becomes southeasterly and increases
to around 10 knots in the afternoons as the sea breeze develops.
Scattered to occasionally numerous showers and lightning storms
will remain a hazard each day and night, some of which have the
potential to become strong. Less favorable boating conditions
develop mid week next week, as high pressure strengthens north of
the local waters, increasing onshore flow.

.GULF STREAM HAZARDS...None.
