Snow and bad road conditions have triggered a "digital day" for multiple Washoe County School District campuses today.
Assignments will be provided digitally to students by the teacher and completed at home.

The National Weather Service in Reno is still collecting regional snowfall totals, but early reports indicate anywhere from 2 to 3 inches (or more) of snow fell in the Reno-Sparks area.
About 3.2 inches of snow was recorded at the Weather Service offices at about 4 a.m. Wednesday morning, according to NWS meteorologist Chris Johnston.
The Reno-Tahoe International Airport reported 2.8 inches at the same time.
Snow has been falling steadily since then, Johnston added, so it's likely those totals are now higher — and they will continue to climb as the morning goes on.
Another band of snow is currently forming over South Lake Tahoe and Carson City and is headed towards Reno-Sparks. Johnston said that band should arrive in the next hour or so and will continue through the morning commute.
Temperatures will remain in the 30's throughout the day and intermittent snow showers will persist.
Johnston echoed the warnings of local law enforcement agencies, who cautioned drivers to pay attention to chain controls and hazardous road conditions.
The weather service is expected to have updated snowfall totals for across the region as the morning goes on.
If you can stay home until the roads begin to thaw this morning, it's probably a good idea.
"From what I can tell, pretty much every single highway in this part of the state has chain controls active ... the roads are pretty much a sheet of ice out there and traction is diminished significantly," said Nevada Highway Patrol Trooper Matt McLaughlin.
He added that the posted speed limit on roadways is not currently a safe speed, "you should really be going well under the speed limit."
McLaughlin said there are a handful of crashes across the region but most of those appear to be non-injury crashes. Highway patrol has also gotten multiple calls for help from stuck or stranded motorists.
If you absolutely have to be on the road, make sure you're being extremely careful out there," McLaughlin said.
Washoe County School District schools - except Incline Village - are on a two-hour delay Wednesday morning after an overnight winter storm caused hazardous conditions on area roads, according to the district.
There will be no early release and winter bus stops are in effect.
The University of Nevada, Reno is opening as normal today and classes at Truckee Meadows Community College are delayed until 9:30 a.m.
TMCC classes before 9:30 this morning are delayed or canceled.
A winter weather advisory remains in place for the entire region this morning and motorists should be wary of chain controls and hazardous driving conditions as they take to roads for the morning commute.
Chain controls are so prevalent in the region that it's actually easier to list which highways are currently unrestricted. Most major arteries in Northwestern Nevada, the Tahoe Basin and over the Sierra are currently chain restricted.
