A blizzard warning for Lake Tahoe has expired but up to another foot of snow could fall Friday and strong winds could cause blizzard-like conditions at times.
A winter storm warning from the National Weather Service will remain in effect until 10 a.m. Saturday, March 3. An additional 8 to 14 inches of snow could fall Friday, with localized amounts up to 20 inches, according to the weather service.
The heaviest snowfall is expected between 2 p.m. and midnight.
"Avoid travel if possible, you could be stuck in your vehicle for many hours," the service warns. "If you must travel, prepare for long delays and carry an emergency kit with extra food, water and clothing."
Schools around the lake, and even down in the Carson Valley, are closed Friday. Snow is expected to continue falling — off and on — until Sunday, when mostly sunny conditions will return to the region.
If there was any doubt about winter's presence in the Sierra Nevada, it was annihilated on Thursday. Snow fell continuously throughout the day, shutting down schools and wreaking havoc on roads.
Warnings from the National Weather Service about blizzard conditions held true as the wind whipped fresh snow into a frenzy and reduced visibility to nothing.
