Warning-level surf expected into Monday

HONOLULU, Hawaii (HawaiiNewsNow) - Another round of extra-large surf is expected to rise into Monday morning, with a high surf warning issued for most north and west shores.

The National Weather Service in Honolulu said the warning will be in effect until 6 p.m. Monday for the north and west shores of Niihau, Kauai, Oahu and Molokai and the north-facing shores of Maui.

Dangerously large breaking waves of 20 to 30 feet with locally higher sets are possible for north-facing shores overnight into early morning, with dangerous waves of 15 to 20 feet along west shores.

Wave heights are expected to peak during the overnight hours into early Monday morning.

While this swell may not be quite as large as the one a few days ago, beachgoers should still be on the alert for ocean water occasionally sweeping across normally-dry beach areas, very strong longshore and rip currents, and very strong and dangerous shore breaks.

Breaking waves may also impact north and west-facing harbors, making it dangerous to navigate harbor channels.

Waves this big will make entering the water very hazardous, and anyone going into the water may face significant injury or death.
