During the weekend, Iras brought significant snow and ice to parts of the Pacific Northwest. Up to an inch of ice was reported in Lane County, Oregon, which includes Eugene, Creswell and Goshen. Eugene, Oregon, also picked up 4.5 inches of snow. Freezing rain and snow impacted the Salt Lake City metro and Portland area Sunday.
Cold air trapped in the valleys of western Colorado also resulted in freezing rain there on Monday. Around the Grand Junction area, near one quarter of an inch of ice had accumulated as of late Monday morning, leading to ice-covered roads and sending cars into ditches.
