...BEACH HAZARDS STATEMENT IS CANCELLED...

Waves have dropped below 3 feet this morning. While there is a
possibility that waves reach and surpass 3 feet by a couple of
inches this afternoon, the time period that this would occur is
shortlived. Therefore the Beach Hazard Statement has been 
cancelled. A moderate swim risk remains for today given lingering
currents and invigorated waves.
