SAN FRANCISCO (AP) — A lengthy stretch of highway in California's Sierra Nevada is closed for the second day in a row because of a winter storm.

The 80-mile stretch of westbound Interstate 80 is shut down from the California-Nevada line just west of Reno to Colfax, California, east of Sacramento.

Chains or snow tires are required on eastbound I-80 and all mountain passes around Lake Tahoe, where more than 3 feet of snow fell in blizzard conditions over the past 24 hours.

A winter storm warning is in effect Tuesday.

More than 6 feet of snow has been reported at the top of some nearby ski resorts since the storm began Saturday.

Government offices in Reno and Carson City opened two hours late because of the weather and schools were either delayed or canceled.
