HAENA BEACH (HawaiiNewsNow) - A high surf warning was posted Friday for the north- and west-facing shores of most islands, and forecasters say wave heights could reach 30 feet in some areas.
Forecasters believe wave heights will remain at warning levels through 6 p.m. Sunday.
The swell is expected to rise through the night, peak on Saturday, and then slowly decline through Sunday evening.
Authorities say to expect ocean water surges and the possibility for damage across coastal properties and infrastructure, including roads and bridges.
Officials want to remind visitors and beachgoers to heed warnings and advisories and listen to ocean safety personnel. Underwater rip currents and violent shore break can easily sweep individuals out to sea.
