A LOW RISK OF RIP CURRENTS IS EXPECTED ALONG ALL
REEFS FOR MOST OF THE WEEK. SURF AND RIP RISK COULD RISE TOWARD THE
WEEKEND ALONG WEST AND NORTH FACING REEFS, AS A NORTHWESTERLY SWELL
EMANATING FROM A DISTANT TROPICAL DISTURBANCE ARRIVES TO THE REGION.
A MODERATE RISK OF LIGHTNING IS EXPECTED FOR MOST OF THE WEEK AS AN
UNSETTLED PATTERN CONTINUES.

MORE FREQUENT RIP CURRENTS. ALWAYS HAVE A FLOTATION DEVICE WITH YOU

CURRENTS, ESPECIALLY ALONG NARROW REEFS AND BEACHES. IF CAUGHT IN A
RIP CURRENT, SWIM PARALLEL TO THE BEACH RATHER THAN AGAINST THE
