…POWERFUL PACIFIC STORMS WILL PRODUCE LARGE NORTHWEST SWELLS AND GIANT SURF ACROSS HAWAIIAN COASTAL WATERS THIS WEEK…
A SET OF VERY POWERFUL STORMS IN THE NORTH PACIFIC WILL PRODUCE A PROLONGED SIGNIFICANT HIGH SURF EPISODE FOR THE NORTH AND WEST FACING SHORES OF MOST HAWAIIAN ISLANDS THROUGH WEDNESDAY. THE FIRST SWELL PEAKED ON SATURDAY AND WILL SLOWLY DECLINE THROUGH TODAY.
A LARGER SWELL IS EXPECTED TO ARRIVE TONIGHT. THIS SWELL IS BEING GENERATED BY A PAIR OF EXTREMELY STRONG STORMS NORTH-NORTHWEST OF HAWAII. THE ORIENTATION OF THESE STORMS HAS CREATED A LONG FETCH OF 40 TO 60 MPH WINDS. THIS FETCH IS SENDING OPEN OCEAN SWELLS OF 18 TO 22 FT TOWARD THE HAWAIIAN ISLANDS. SURF WILL BUILD RAPIDLY TONIGHT AND REACH HEIGHTS OF 30 TO 40 FEET WITH 50 FOOT SETS ON OUTER REEFS EARLY MONDAY THROUGH TUESDAY NIGHT. SURF WILL REMAIN ABOVE WARNING LEVELS THROUGH WEDNESDAY.
BOATERS NEED TO EXERCISE EXTREME CAUTION IN COASTAL WATERS THIS WEEK. BREAKING WAVES WILL OCCUR WELL OFFSHORE IN AREAS NOT TYPICALLY SEEN. THE LARGE SWELLS WILL ALSO CREATE STRONG AND UNUSUAL CURRENTS IN NEAR-SHORE WATERS. HARBORS EXPOSED TO NORTHWEST SWELLS MAY SEE STRONG HARBOR SURGES CAPABLE OF DAMAGING MOORED VESSELS. WAVES BREAKING ACROSS HARBOR ENTRANCES WILL BE AN ADDITIONAL THREAT.
