If you're thinking this may be the perfect time to head to Tahoe, think again. A Blizzard Warning is in effect for the Sierra from 10 p.m. Tuesday night through Friday. The National Weather Service is forecasting life-threatening white-out conditions with wind gusts over 100 mph over ridges.
"Travel will be impossible at times," says Tuma.
"We could have whiteout conditions. Blizzard conditions. I would not be surprised if several highways and interstates are closed in the high country," Nicco says.
