Palm Springs has been totally cut off and people are unable to call 911 after Storm Hilary drenched Southern California on Sunday. Now there are fears that Burning Man could be washed out as the deserts of Nevada are pounded by the storm. Hilary crossed into Nevada at 5am ET Monday and the weather system will head into Idaho and Montana in the early hours of Tuesday. Southern California was battered yesterday with the city of Palm Springs receiving more than half a year's worth of rain in just a few hours. Residents have been warned that 911 lines are down and the mayor admitted: 'There's no way in or out.' Around 100 miles west, footage showed Dodger Stadium in Los Angeles surrounded by a moat of rainwater. Schools across SoCal and Nevada were shuttered on Monday and 800 flights were cancelled. Travelers are warned of travel disruption at San Diego International Airport, Nevada's Harry Reid and Phoenix's Sky Harbor.
