UPDATE: 1:30 p.m.

The National Weather Service has added portions of Kauai and Oahu to its high wind warning, effective until 6 p.m. today.

Southwest winds of 25 to 30 mph, with localized gusts up to 60 mph, are blowing in windward and interior Kauai and Oahu, officials warned.

Damaging winds may blow down trees and power lines and lead to property damage, and lead to hazardous driving conditions due to powerful crosswinds, especially for lightweight and high-profile vehicles.

Power outages are possible, and are already affecting thousands of customers on Oahu.

A high wind warning is also in effect for the summits of Haleakala on Maui and Mauna Loa and Mauna Kea on Hawaii island until 6 p.m. Wednesday.

Southwest winds of 35 to 75 mph, with localized gusts over 90 mph, will impact summits, and travel should be postponed until conditions improve.

A wind advisory remains in place through midnight for other parts of the isles.

11:30 a.m.

The flood advisory for the island of Maui expired at 11:30 a.m., but not before wreaking havoc.

Maui County officials reported numerous road closures, while firefighters responded to multiple flood-related calls along South Kihei Road this morning.

Around 8:45 a.m., Maui Fire Department’s Air One helicopter rescued two people from their vehicle, which was trapped in fast-rising floodwaters along South Kihei Road near Kaonoulu Street. Maui firefighters also helped another three people to safety on foot from vehicles stalled in floodwaters.

MPD reported several flood-related road closures, including South Kihei and Kaonoulu; South Kihei near Uwapo Street; South Kihei Road from North Kihei to Kulanihakoi Road; Hana at Hanakai; and Piilani Highway from Mile Marker 19 to 21 in Kaupo.

The following parks on Maui remain closed due to flooding: Kalepolepo Beach Park in Kihei, Kanaha at Ka’a Point in Kahului and Hana Ball Park in Hana.

On Hawaii island, Onekahakaha Beach Park in Hilo will remain closed today.

On Oahu, more than 13,000 people are without power this morning, according to Hawaiian Electric’s outage map — from Ala Moana and Kakaako to Aina Haina, Hawaii Kai, Waimanalo, Kailua, Kaneohe and Temple Valley.
