Snow, some slippery roads and temperatures hovering around the freezing level greeted Spokane on Friday morning. Police report several minor accidents and cars that have slid off the road. About four inches were reported in Deer Park. Amounts were less in north Spokane and on the South Hill where the City of Spokane street crews focused six of their de-icer trucks on most of the arterials early this morning. Another shift of street crews are lined up to monitor conditions and work Saturday morning if needed, says streets department spokeswoman Ann Deasy. The snowfall will increase later today, perhaps bringing another inch across Spokane north of Interstate 90 and heavier amounts to the Idaho Panhandle. The big low-pressure system that moved across the area last night, dumping six inches of snow in Pend Oreille County, continues to push north. Isolated roads about 2,000 feet will have hazardous driving conditions, but road temperatures in the majority of the region should rise above freezing by late morning.
