Life Heat Waves, Wildfires, Snow: California Endures a Summer of Extremes

An unusually cold weather system from the Gulf of Alaska interrupted summer along the West Coast over the weekend, bringing snow to mountains in California and the Pacific Northwest and prompting the closure of part of a highway that runs through a national park.

Parts of Highway 89 through Lassen Volcanic National Park in California were shut down after an estimated 3 inches of snow fell Saturday, according to the National Weather Service.
