Gusty winds that toppled trees and damaged part of the Koko Head Shooting Complex on Tuesday night slowed a bit Wednesday but strong breezes will continue today, according to the National Weather Service.

Winds of 15 to 25 mph are expected today, the Weather Service said.

On Oahu’s Leeward side, a downed power line Wednesday morning prompted closure of McArthur Street, blocking access to Waianae Elementary School. Parents were advised to use Plantation Drive to get to the school.

According to the National Weather Service, Wednesday’s winds were estimated at 50 to 60 mph, with gusts up to 75 mph at the summits.

City officials said high winds kept firefighters busy Tuesday night, responding to calls of downed trees in Waipahu, Kunia, Wahiawa/Schofield area and Hawaii Kai. Toppled trees were also reported at Waialae Iki Neighborhood Park on Kalanianaole Highway and Mililani District Park.

At the Koko Head Shooting Complex, one person was injured when winds took off the roof of a structure and flipped it over, a Fire Department spokesman said.

Lifeguards also were busy pulling swimmers out of the surf generated by the high winds Tuesday.

At Lanikai Beach, a lifeguard on a rescue watercraft helped 13 people get to shore safely between the beach and the Mokulua islands.

On the south shore, lifeguards in Waikiki Beach towers rescued five people while lifeguards using rescue watercraft rescued eight others.
