This is foreign to me, because on the East Coast, when we have an actual blizzard, they declare a snow emergency and you're not allowed on the roads. Human nature being what it is, I guess people just wanted to get home. If you're in the affected area, I hope you're warm and dry! Via the Associated Press:

RENO, Nev. (AP) — A powerful blizzard raged overnight into Saturday in the Sierra Nevada as the biggest storm of the season shut down a long stretch of Interstate-80 in California and gusty winds and heavy rain hit lower elevations, leaving tens of thousands of customers without power.

Up to 10 feet (3 meters) of snow is expected in some areas. The National Weather Service in Reno said late Friday it expects the heaviest snow to arrive after midnight, continuing with blizzard conditions and blowing snow through Saturday that could reduce visibility to one-quarter mile or less.

“High to extreme avalanche danger” is expected in the backcountry through Sunday evening throughout the central Sierra, including the greater Lake Tahoe area, the weather service said.

California authorities on Friday shut down 100 miles (160 kilometers) of I-80 due to “spin outs, high winds, and low visibility.” They had no estimate when the freeway would reopen from the California-Nevada border just west of Reno to near Emigrant Gap, California.
