High surf warning downgraded to advisory

HONOLULU (HawaiiNewsNow) -

The National Weather Service says a storm in the North Pacific has generated a large west-northwest swell that is on Thursday afternoon and will continue to through the evening.

FRIDAY MORNING UPDATE: The National Weather Service has downgraded a high-surf warning issued Thursday to a high-surf advisory until 6 a.m. Saturday. 

The high surf warning is in effect for the north and west facing shores of Niihau, Kauai, Oahu, Molokai and the north facing shores of Maui. 

The warning expires 6 a.m. Friday.

According to the warning, surf along north facing shores will be at heights of up to 20 to 25 feet through tonight. Along the islands' west facing shores, surf will build to 15 to 20 feet.

Beachgoers should expect ocean water occasionally sweeping across portions of beaches, along with very strong breaking waves and strong long shore and rip currents. Breaking waves may occasionally impact harbors making navigating the harbor channel dangerous, the N.W.S. says.

Kauai officials have closed all north-facing beaches, including Anahola, due to high surf conditions.

Ocean Safety officials report hazardous ocean conditions with waves over 20 feet high.

Kauai lifeguards will remain at the beach towers throughout the day to notify beachgoers of the closure.
