(CBS News) -- A mudslide forced a home off of its foundation and down a hillside in Northern California, crashing it into another home early Thursday morning, authorities said. A woman was left trapped inside the home that came off its foundation in Sausalito, the Marin County Sheriff's Office said on its Facebook page.
"We are so grateful the woman is ok and we want to thank the Fire Department for saving this woman from what could have been a terrible tragedy," the sheriff's office said. More than 50 homes in the area were evacuated as a precaution, Tubbs said.
A weather phenomenon known as an atmospheric river has been hitting the West Coast, drenching parts of California and southern Oregon with large amounts of rain.
