(BIVN) – A High Wind Warning is now in effect for Hawaiʻi Island summits until 6 p.m. Monday, as a powerful area of low pressure to the north moves toward the islands this weekend.

According to the National Weather Service in Honolulu:

For the Big Island summits of Mauna Kea and Mauna Loa, west winds 45 to 65 mph this morning, increasing to 60 to 80 mph this afternoon, then increasing to 80 to 100 mph tonight. Even stronger west winds are expected Sunday and Sunday night, with speeds reaching 90 to 120 mph with higher gusts. Winds will begin to decrease on Monday but are expected to remain at warning levels.

The Mauna Kea Access Road has already been closed.

“The access road to the summit of Maunakea is closed to the public at the Visitor Information Station at the 9,200 feet level due to below freezing temperatures, high winds in excess of 40 mph and gusting to 60 mph, and the latest forecast which calls for possible fog, ice and increasing winds,” the Maunakea Rangers stated at 3:52 a.m. “Rangers will continue to monitor road and weather conditions and this message will be updated accordingly,” the message said.

The Mauna Loa summit has been temporarily closed, Hawaiʻi Volcanoes National Park says. Pu‘u‘ula‘ula (Red Hill Cabin) remains open.
