The fast-moving cold front is expected to sweep through the island chain Friday, bringing “potentially dangerous weather” to Hawaii, the National Weather Service said.

Gusty southwest winds, strong to severe thunderstorms and blizzard conditions are possible starting Friday afternoon, the National Weather Service warns.

“Southwest winds will increase today ahead of the front, becoming strong and gusty across Kauai and Oahu this afternoon and across Maui County and the Big Island tonight. Strong thunderstorms with gusty winds along with heavy downpours will develop ahead of and along the front,” the National Weather Service said in a severe weather statement Friday morning.

A blizzard warning and high wind warning are posted for Mauna Kea and Mauna Loa until 6 p.m. Saturday. 

Hurricane-force winds of 55 to 90 mph, with gusts over 130 mph are expected and temperatures are expected to drop into the low 20s at the summits.

Forecasters said up to a foot of snow, with “much higher drifts” are expected Friday night and Saturday that could create “life-threatening conditions for anyone attempting travel to the summits.”

A high wind warning is also posted for Kauai County, Oahu’s North Shore, Central Oahu and the Waianae mountains until 6 a.m. Saturday. Northwest winds of 15 to 35 mph with gusts over 60 mph are expected.

A wind advisory for Maui County, Hawaii island and Oahu’s south shore until 6 a.m. Saturday. Southwest winds of 25 to 35 mph with gusts over 50 mph are possible with the strongest winds in areas where winds accelerate downslope.

“Winds this strong can bring down tree branches and make driving difficult, especially for high-profile vehicles,” forecasters said.

“The most likely time for adverse weather to occur will be this afternoon into early this evening across Kauai, this evening into the overnight across Oahu and Maui County and late tonight into Saturday morning across the Big Island,” the weather service said.

The high-wind advisory for Hawaii island was issued until 6 a.m. Saturday. According to NWS, the high winds are expected to strengthen as they pass through the Saddle Road area. Motorists are advised to be prepared for high winds, heavy rains, and ponding on roadways as well as possible unexpected road closures.

The state and Hawaii County canceled all camping permits for Waimanu Friday because of the weather.

The Department of Land and Natural Resources’ Division of Forestry and Wildlife and the Hawaii County Civil Defense also closed the Waimanu trail in North Kohala Friday. 

The closure is expected to remain in effect through the weekend, according to a news release by DLNR. 

The state also closed the Kalalau Trail on Kauai’s Na Pali Coast State Wilderness Park. 

The forecast for Honolulu and south shores of Oahu calls for a 70 percent chance of rain Friday and a near-100 percent chance of rain Friday night, with locally heavy rainfall and thunderstorms possible.

The windy and stormy conditions should lessen after midnight on Oahu. Saturday morning should bring mostly sunny conditions and scattered showers.

Cool and dry weather is expected behind the front on Sunday, with a relatively dry tradewind pattern resuming early next week, the weather service said.
