The cloud wall was forecast to move over or near the islands southern end by the evening, lashing its worst winds at volcanic slopes thousands of feet above sea level.

Shelters have been opened, events were cancelled and ranchers have been urged to leave their cattle in pastures.

Earlier the governor called it an enormous storm, capable of destructive flooding and even the possibility of wildfires kicked up by strong winds across the island chain.

Electricity was knocked out for nearly 20% of customers on the Big Island, according to poweroutage.us .

Mike Caputo, who lives in Keaau, near the Big Island’s east coast, fears flash flooding.

He readied his power generator and checked his 10,000-gallon water tank, in preparation for the extreme weather.

Bobby Camara, a 75-year-old lifelong resident, said he planned to hunker down and cross his fingers.

He said gas stations were busy as people sought fuel for chain saws and vehicles.
