Reno-Tahoe International Airport spokeswoman Trish Tucker says the storm has caused four cancellations and 13 delays so far.
Washoe County School District officials in Reno say all school sporting events and activities are being canceled through Monday.
The storm also has prompted widespread chain controls on highways in the region, including on Interstate 80 over Donner Summit.
The National Weather Service says the storm should be the start of a prolonged stormy period lasting through the middle of next week.
The storm is expected to bring 3 to 6 feet of snow to higher elevations around Tahoe by Sunday afternoon.
