A rare blizzard warning has been issued for the Big Island of Hawaii, with a large amount of snow anticipated.

The National Weather Service issued an “urgent” warning Friday ahead of a huge storm hitting the state, which generally has a tropical climate.

“Blizzard warning for the Big Island summits,” reads the weather advisory. “Travel could be very difficult to impossible. Blowing snow will significantly reduce visibility at times, with periods of zero visibility.”

The warning is in place from 6 p.m. Friday to 6 a.m. Sunday local time. A high-wind warning has also been put into effect.

Winds are anticipated to gust over 100 mph, and total snow accumulations may be up to a full foot “or more.” Additionally, the strong winds “will likely cause significant drifting of snow.”
