RENO, Nev.—A winter storm packing powerful winds, heavy rain and potentially several feet of snow in the Sierra Nevada shut down mountain highways, toppled trees and triggered flood watches and avalanche warnings on Saturday from the coast of Northern California to Lake Tahoe.

More than 250 miles of the Sierra remained under a winter storm warning at least until Sunday night or early Monday from north of Reno to south of Yosemite National Park.
