Intense rain, heavy snow and strong winds lashed California and southern Oregon on Friday, prompting the evacuation of more than a hundred homes threatened by mudslides near Los Angeles, officials said.

The Los Angeles Fire Department said within four hours on Friday afternoon it responded to 150 reports of downed wires, one of which led to a fatality. Los Angeles area utilities said power was out for more than 100,000 customers in the region.

The severe storm could bring California's heaviest rainfall in six years, after months of wet weather that has dramatically eased California's years-long drought. The heavy rain and melting snowpack threatened to undermine a spillway at one of the largest dams in the country, which prompted the evacuation of 188,000 residents earlier this week.
