A new storm will hit the West Coast Monday before moving across the country. It is set to bring extreme weather such as snowfall, severe thunderstorms and rain that may cause flooding.

Washington and Oregon could see landslides as the storm moves through Monday afternoon and night. Oregon already saw a landslide Sunday, which shut down its historic Columbia River highway.

An avalanche warning has been issued from Oregon to Montana, where some areas could see up to 30 inches of snow.
