What You Should Do

For the latest road conditions, call 5-1-1.
Expected Conditions
Heavy snow is expected at elevations above 2,000 feet, with additional snow accumulations of up to 6 inches. There is potential for snow levels to drop as low as 1,500 feet during the heaviest snowfall. Strong winds are also expected; the combination of wind and the weight of snow on tree limbs may down power lines and cause sporadic power outages.
