Residents of mountain communities in California have been stuck in their homes with little food following what meteorologists are calling "once-in-a-generation" snowfall. 

The severe weather knocked out power, and snow led to roof collapses. 

County workers took more than 500 calls for aid – including asking for baby formula and medicine – on Wednesday while firefighters worked to evacuate the most vulnerable and fight possibly storm-related explosions. 

The onslaught of storms led to as much as 10 feet of snow for some resort communities, according to the National Weather Service.

"This rain and snow bucked the trend, and it’s highly unexpected," Ryan Maue, a meteorologist and former NOAA chief scientist, told The Associated Press. "It’s like once-in-a-generation."
