UPDATE: 4:30 p.m.

The National Weather Service has canceled the wind advisory, saying winds continue to slowly weaken and have fallen below advisory levels.

The winter storm warning for Hawaii island summits has also been canceled, and the high surf warning has been replaced with a high surf advisory.

A high surf advisory is now in place for the east-facing shores of Kauai, Oahu, Molokai, Maui, and Hawaii island through 6 p.m. Friday.

Surf of 8 to 12 feet along these shores today is expected to subside to 7 to 10 feet on Friday afternoon. Strong, breaking waves and strong currents will make swimming dangerous.

A small craft advisory is also in place for most Hawaiian waters through 6 p.m. Friday.

The National Weather Service has canceled the wind advisory for Kauai and Oahu in an update posted at about 1:15 p.m..

The wind advisory remains in effect for Maui County and portions of Hawaii island through 6 p.m. today.

“Robust high pressure well north of the state will continue to produce strong and gusty trade winds across Maui County and Big Island, expect for the Kona, Hilo and portions of the Puna districts,” said NWS in the update. “However the winds across Kauai and Oahu continue to weaken and have largely fallen below advisory levels. The Wind Advisory may need to be extended across the western islands tonight.”

In areas under advisory, east winds of 20 to 30 mph are expected, with localized gusts up to 50 mph.
