Rain Storms Threaten Parched Southern California With Mudslides

AZUSA, CA - FEBRUARY 28: An ash-filled waterfall flows in the Colby Fire burn area as a storm brings rain in the midst of record drought on February 28, 2014 near Azusa, California. The rain offers some relief to the dry conditions but is not expected to be enough to break the historic drought. A drought-related unseasonal wildfire, the Colby Fire, was accidentally ignited in the dry chaparral vegetation in January, destroying homes and sending thousands fleeing. The charred and denuded hillsides are threatening the homes of about a thousand evacuated residents with rain-loosened mud-ash debris flows. (Photo by David McNew/Getty Images)
