A storm will barrel across the West Coast this week, bringing much-needed rain and some mountain snow for the first time since early spring.

Showers began breaking out across Oregon and Northern California on Monday morning. Rain and high-elevation snow are forecast to expand as the storm dives southward along the Pacific coast.

"The rain will come fast and furious Monday afternoon in the Bay area and by Monday evening in the Central Valley of California," said AccuWeather Meteorologist Chad Merrill.

Widespread rainfall amounts of 0.75 to 1.25 inches are expected from Redding, California, to Los Angeles.
