A car is seen submerged in mud in Daly City, Calif., on Tuesday.

A Daly City, Calif., neighborhood woke up Tuesday morning to face floods, mudslides and evacuations.

At least a dozen homes were evacuated and at one point, at least 100 people were reported to be without power.

Firefighters told NBC Bay Area that 8-inch cast iron pipe attached to a 978,000-gallon water tank ruptured about 4:45 a.m., causing 45,000 gallons of water to spew out down Lusanne Avenue in the Hillside Park area.  The water was stopped by 6 a.m.

An aerial view of the neighborhood showed several cars submerged under a deluge of mud. Crews were busy trying to dig some of those cars out later in the morning.
