The blizzard was especially severe in the mountainous Sierra Nevada region, where wind gusts reportedly reached 305km/h.

People have been warned of a "high to extreme avalanche danger" there, including the greater Lake Tahoe area.

power outage map showed more than 33,000 people in Nevada and nearly 24,000 in California without electricity.

A 121km stretch of the Interstate 80 highway was shut down on Saturday. The California Highway Patrol Office in Truckee, close to the state border with Nevada, said on X (formerly Twitter) that "emergency personnel and tow trucks had a difficult time getting to motorists due to blizzard conditions."
