The mobile kitchens are just a drop in the bucket of the federal and local governments' plan to prepare for "the worst case scenario," Cavallero said.
He said each mobile kitchen can prepare 3,000 to 5,000 meals a day, which would be provided by emergency response if needed.
"Best case scenario, everyone's going to get there, sit around and look at each other and say 'OK, I'm bored,'" he said.
He said the kitchens were used continuously during the recent dry lightning storms that started hundreds of fires in California.
Last time the Salvation Army was asked to volunteer at an event "just in case" of an emergency situation was in Salt Lake City at the winter 2002 Olympics after the Sept. 11 attacks, he said.
Salvation Army volunteer teams from Napa, Concord and San Francisco will meet in Cordelia at 6 a.m. to travel about 1,200 miles to Denver.
