Snow now falling in the Spokane region could bring 3 to 5 inches of accumulation while accidents started to occur late this morning.
Westbound traffic on Interstate 90 was slowed at Evergreen Road due to a crash about 11:30 a.m.
The National Weather Service late this morning upgraded a winter weather advisory to a winter storm warning. Forecasters said they expect the region overall to see 4 inches of snow with amounts varying by location.
Another inch could fall in the urban area tonight. Coeur d’Alene could see 1 to 2 additional inches tonight.
Deeper snow amounts are possible in the Palouse, central Panhandle and Silver Valley where 4 to 9 inches of snow could fall today. The mountains might see even more.
Spokane street crews had applied deicer to city streets prior to the storm and were continuing with a full crew to keep streets clear through the day, a city spokesman said.
The snow storm will likely be the largest of the season, and today’s accumulation could surpass the 3.3 inches of snow measured so far this season at Spokane International Airport.
The high today is forecast at 30 degrees with a low overnight of 25.
The snow eases off on Saturday, but another storm packing rain and snow is expected on Monday.
Today’s storm is bringing much-needed precipitation to the region. Spokane is nearly 3 inches below normal for precipitation since Oct. 1.
