The week is starting with wild weather for the West Coast.
As Southern California faces dangerous flooding, unusual snowfall struck Seattle Monday morning, prompting all of the city's public schools to close.
The wind chill in Seattle plunged to 10 degrees Monday. The National Weather Service is urging residents there to stay off the roads if possible.
Meanwhile, in Southern California, strong storms sparked dangerous mudslides, harsh winds and flash floods this weekend.
Heavy rain triggered flash flooding in Santa Barbara County, where half an inch of rain fell in just five minutes.
