One week after summer’s end, a “winter” storm began blasting parts of the West with up to 3 feet of snow, smashing records with low temperatures, heavy snow, strong winds and blizzard conditions forecast into Monday.

Snow was piling up across parts of California, Oregon, Washington, Montana, Idaho, Nevada and Utah. The National Weather Service, calling the storm “historic,” said temperatures in some areas would drop as much as 30 degrees below normal.
