Heavenly Mountain reported 12 inches of snow in 24 hours Thursday morning.
Several ski resorts in the Tahoe area, including Squaw Valley Alpine Meadows and Northstar California, reported receiving two feet of snow between Tuesday and Wednesdayand that's before the brunt of the storm hit.

The snow continued to pile up Wednesday night into Thursday morning, as the storm dumped wet, heavy 'Sierra cement' in the Tahoe basin.

The resorts started to boast about how much snow fell in their neck of the woods and the numbers were impressive all around. Sugar Bowl had received 15 inches of snow just overnight. Squaw Valley reported 28 inches of snow in the past 24 hours, Northstar had 26 inches, Kirkwood had 16 inches, and Heavenly had a foot. June Mountain Ski Area reported a 24-hour total of 36 inches at 7 a.m. Thursday.

"I would call this storm extremely dangerous," said Karleisa Rogacheski, a meteorologist with the NWS Sacramento office. "During whiteout conditions, it's going to be near-impossible to drive."

Wednesday afternoon there were already major problems on I-80. The California Highway Patrol was forced to close the the interstate in both directions due to multiple crashes in the westbound lanes and a jackknifed semi-truck in the eastbound lanes at Donner Summit. The roads were reopened about an hour later.
