A massive storm continued to pound California Wednesday, threatening the state's fire scarred hillsides.
    
Forecasters are predicting 3 to 6 inches of rain and hurricane-force winds. Areas that just recently had experienced wildfires are considered especially vulnerable.

"We've got the potential for some of the biggest landslides we've seen in a century," said Lucy Jones of the U.S. Geological Survey. "This is the fastest I've seen it rise. It only took about four hours."

Many communities that just recently battled wildfires are now resorting to sand bags as they brace for mud slides and flash flooding. 

The rain threatens a 400-mile span of The Golden State from San Francisco to Los Angeles. 

Officials in the Santa Cruz area have evacuated some residents. And more than a quarter of a million Californians are without power after high winds knocked out high-voltage lines.
    
The unrelenting downpours have already flooded streets, toppled trees and canceled flights at San Francisco's International Airport. 
    
Also, the rains have caused hundreds of accidents around the state.
