A wet, winter storm that dumped another foot of snow in the Sierra snarled traffic around Lake Tahoe and brought snow to the valley floors Wednesday around Reno and Carson City.
Chains or snow tires were required on Interstate 80 west of Reno and all roads over mountain passes and around Lake Tahoe Wednesday morning.
A jackknifed tractor trailer closed the eastbound lanes of I-80 just east of Soda Springs, Calif., early in the day. Chains also were required on U.S Highway 395 headed north out of Reno and headed south out of Carson City.
"We have very heavy snow on I-80 near Verdi" just west of Reno, Nevada Highway Patrol Trooper Robert Stepien said Wednesday. He reported numerous minor traffic accidents, especially in the foothills on the north and western edge of Reno.
"People really need to slow down. Even if you are doing the speed limit, if you are over the speed for the conditions, you will be cited," he said.
Reno and Carson City were expected to receive up to 2 inches of snow before the storm moved east Wednesday afternoon while 6 to 10 inches was anticipated above 5,000 feet and as much as 20 inches of snow at the higher elevations above 7,000 feet.
Alpine Meadows ski resort near Lake Tahoe reoprted 12 new inches of snow over night. About 6 inches of snow had fallen early Wednesday morning at South Lake Tahoe, Calif., and snow forced a two-hour delay in the start of school at Incline Village on the north end of the lake.
