    NATIONAL WEATHER SERVICE

    A winter storm warning, wind advisory and small craft advisory are in effect for areas of the Hawaiian islands.

UPDATE, 7 p.m.

The flood advisory for the island of Hawaii has expired.

A winter storm remaining also remains in effect for Big Isle summits until 6 a.m. Wednesday due to significant ice accumulations of up to about three-tenths of an inch.

4:15 p.m.

The flood advisory for the island of Hawaii has been extended until 6:15 p.m. today.

Radar this afternoon indicated areas of moderate to heavy rain, and a few thunderstorms, over the lower Kona slopes from Kailua-Kona to Hawaiian Ocean View. The heaviest showers were producing rainfall rates between 1 and 2 inches per hour.

1:30 p.m.

The National Weather Service has issued a flood advisory for the island of Hawaii, effective until 4:15 p.m. today.

At 1:08 p.m., radar indicated heavy rain over the lower Kona slopes from Keahole Point to Milolii, with the heaviest showers producing rainfall rates between 1 and 2 inches per hour.

Some locations that will experience flooding include Kailua-Kona, Captain Cook, Honaunau, Kealakekua, Kainaliu, Honalo, Kahaluu-Keauhou, Holualoa, Hawaiian Ocean View, Kalaoa, Milolii, Hawaii Volcanoes Park Kahuku Unit and Kona International Airport.

The public should stay away from streams, drainage ditches and low-lying areas prone to flooding.

The advisory may be extended beyond 4:15 p.m. if flooding persists.

EARLIER TODAY

The National Weather Service has issued a wind advisory for portions of Maui County and Hawaii island, effective until 6 p.m. today.

Forecasters say northeast winds of 20 to 30 mph, with localized gusts up to 50 mph, are expected today on Kahoolawe, Lanai, parts of Maui, Molokai and Hawaii island.

“Winds this strong can tear off shingles, knock down tree branches, blow away tents and awnings and make it difficult to steer, especially for drivers of high profile vehicles,” said NWS in the advisory. “Watch out for falling tree branches when walking or driving. Make sure tents and awnings are secure or take them down. Be prepared for power outages.”

Forecasters expect a “wet trade wind pattern” with isolated thunderstorms and locally heavy rain to prevail through Wednesday night, especially over windward areas. Also, moderate to breezy tradewinds are expected to continue, and to further strengthen midweek.

A winter storm remaining also remains in effect for Big Isle summits until 6 a.m. Wednesday due to significant ice accumulations of up to about four-tenths of an inch.

Travel to Big Isle summits “could be nearly impossible,” says NWS, and should be postponed until the threat diminishes.

A small craft advisory is also in effect for Maalaea Bay, Pailolo and Alenuihaha channels, and leeward and southeast waters of Hawaii island until 6 a.m. Thursday.
