HONOLULU (HawaiiNewsNow) –
Giant waves with 40 to 50 foot faces are starting to roll into north shore beaches.
The National Weather Service says that an intense storm northwest of the Hawaiian Islands triggered this super swell.
Waves from the storm have been rapidly building throughout the morning and should peak this afternoon and hold strong well into the evening.
The National Weather Service is still forecasting waves with 40 to 50 foot faces for north shores, with west shore waves possibly reaching 20 to 30 feet.
West shores of the Big Island may have waves of 12 to 18 feet.
The National Weather Service says around 9 a.m. Buoy1, which measures open ocean swells northwest of the Hawaiian Islands, measured an ocean swell of 31 feet at 17 seconds, that translates to 50+ feet on the north shore around 7 p.m. tonight.
Currently a high surf warning is in effect until 6 a.m. Friday for the north and west shores of Niihau, Kauai, Oahu and Molokai, the north shore of Maui and the west shores of the Big Island of Hawaii.
The wave heights could be the largest we have seen in decades. “Back on Feb. 23, 1986 we saw swell heights of about 30 feet with periods of 20 seconds and what that translates to is really big surf, over 50 feet and that is similar to what we seeing today,” said Robert Ballard Meteorologist at the National Weather Service.
The high surf and dangerous currents will make it extremely hazardous to approach the shoreline and result in significant injury or death. Significant coastal inundation and property damage is also possible, so road closures may be likely. Large breaking waves may also make it impossible to enter or leave harbors, including Kahului Harbor on Maui and Waianae Boat Harbor on Oahu.
