The National Weather Service has extended a flood watch for areas north of San Francisco as a plume of moisture known as an atmospheric river inundates Northern California and the Pacific Northwest.

Heavy downpours fell over much of Northern California on Friday, causing small landslides, overflowing a river and flooding some streets, including in parts of San Francisco. Meanwhile tens of thousands of people were still without power in the Seattle area after several days in the dark.
