National Weather Service forecasters in Honolulu warned today that a “very windy weekend” awaits the islands, and issued a high wind watch for Saturday for much of the state.

“A cold front will approach the state from the northwest today and this evening, then move down the island chain late tonight and Saturday, while a strong high pressure system passes north of the islands through the weekend. This combination will bring increasing winds to western and central parts of the state late tonight, and very windy conditions to all islands Saturday through Sunday,” forecasters said in a special weather statement.

The high wind watch is in effect from Saturday afternoon through late Saturday night, with localized gusts over 60 mph possible, the weather service said. By island, forecasters said, Kauai will see the strongest winds in leeward areas from Barking Sands to Koloa; Oahu can expect the highest winds over and immediately west of the Koolau and Waianae ranges; in Maui County, the strongest winds will be in the leeward of the mountainous areas across Lanai and Kahoolawe, and through the central valley of Maui; and the Big Island will experience top winds in the leeward Kohala area, from Waimea to Kawaihae, western Saddle areas, and north of Kailua-Kona.

Possible effects from the high winds include broken and falling tree branches, downed power poles and lines, fallen trees, and flying debris, according to the weather service.

Honolulu’s forecast for Saturday and Sunday calls for highs in the upper 70s, northeast winds of 20 to 30 mph with gusts up to 55 mph, and a 50 percent chance of rain.

Weather service forecasters said that the strongest winds will be over higher terrain, through mountain gaps, and down slope of the mountains.

“Loose outdoor objects may become airborne under these strong winds. Prepare now by securing these objects before winds increase. The strong crosswinds may bring hazardous driving conditions, especially for high profile vehicles,” the statement continued. “If you have outdoor plans for the weekend, be prepared for very windy conditions. If your plans involve marine activities, you may want to consider postponing them.”

A small craft advisory for Hawaii waters is in effect and a gale watch is in set for Saturday afternoon and Sunday afternoon over portions of Maui County and Big Island coastal waters, forecasters said.

A high surf advisory continues for the north and west shores of Oahu, Molokai and Kauai County, the north shore of Maui and the west shore of Hawaii island. Waves up to 10 to 15 feet are expected for the north and west shores of Molokai and Kauai County, and the north-facing shores of Oahu and Maui. The west shores of Oahu could see 8- to 12-foot waves. And Hawaii island’s west shore could see surf up to 6 to 8 feet, according to weather officials.

The advisory is in effect through 6 a.m. Saturday.
