Gusty southwest winds 30-40 mph preceded the storm system and attendant cold front, bringing the increased potential for travel, aviation, and recreation impacts, especially across higher elevations of the eastern Sierra.  Snow began in the Sierra & northeast California Saturday morning with peak snowfall Saturday afternoon through evening, and again overnight into Sunday morning.

Heavy, deep snow covering most road ways lead to extended road closures for many Mono county state highways and roads, especially along US 395 from Bridgeport to Mammoth Mountain valley.
