...LONG PERIOD SWELLS FROM HURRICANE MARIA CONTINUE TO PRODUCE 
HAZARDOUS BEACH CONDITIONS...

HURRICANE MARIA IS FORECAST TO MOVE NORTHWARD WELL EAST OF, AND
PARALLEL TO, FLORIDA'S ATLANTIC COAST MAKING ITS CLOSEST APPROACH
TODAY. MARIA WILL CAUSE THE WINDS AND SEAS TO BECOME ELEVATED 
ACROSS THE COASTAL WATERS WHILE ALSO CAUSING LONG PERIOD SWELLS TO
PROPAGATE TOWARD THE EAST CENTRAL FLORIDA SHORELINE. THIS WILL 
MAKE FOR HAZARDOUS BEACH AND BOATING CONDITIONS. THE RISK FOR RIP 
CURRENTS WILL BE HIGH AND SURF WILL REMAIN VERY ROUGH.
