Hawaii is facing a dangerous high surf warning due to waves reaching up to 40 feet. The warning, issued by the National Weather Service, advises against swimming and beach activities. Large waves pose a threat to infrastructure and public safety.
A high-surf warning issued in parts of Hawaii advises potential beachgoers to avoid the shore, as waves stretching up to 40 feet pound the Aloha State. The high-surf warning remains in effect until 6 p.m. Thursday. Large breaking waves could cause damage to infrastructure near certain shores in Hawaii this week. Swimmers and beachgoers also could be at risk of injury, as the surf hit 40 feet in some places.
The National Weather Service (NWS) office in Honolulu first issued the high-surf warning on Friday, with the alert saying an 'extra-large' swell was expected to peak on Wednesday, which would produce 'dangerously large surf' on north- and west-facing shores. Affected beaches include north- and west-facing shores of Niihau, Kauai, Oahu and Molokai, as well as north-facing coasts in Maui. The surf was highest, up to 40 feet, on north-facing shores, and waves up to 30 feet were expected for those facing west. The swell is expected to gradually diminish on Thursday and Friday. Average surf for this time of year is 12 to 16 feet. The dangerous waves are often caused by long-period large swells generated by a storm system near Alaska. A small craft advisory is also in place, warning inexperienced mariners, especially those operating small vessels, against navigating the waters, as seas were expected to be hazardous. NWS meteorologist Genki Kino told Newsweek: 'We have just been really active in the north Pacific with a series of storms off to the northwest. We get into these active patterns with back-to-back swells. January is on average our biggest time of year on the north shores.' While discussing 40-foot waves, NWS meteorologist Tina Stall previously told Newsweek: 'Those waves are nothing to mess around with. If they're high enough, we can also get some overwash up the beaches and onto the roadways if they're nearby.
