According to a press release, the governor has also activated the State Operations Center to help with county-led emergency response efforts, especially in San Bernardino County.
Residents are dealing with as much as 7 feet (2 meters) of snow, and sheriffs' authorities have conducted 17 rescue operations to help off-roaders and skiers. Emergency crews are trying to reach residents who need assistance.
In Crestline, the entire roof of Goodwin and Sons Market collapsed Wednesday as safety inspectors were onsite checking up on reported damage. Officials raced to salvage food that residents sorely need from its shelves.

"We know that roofs are starting to collapse," she said. "There are other businesses that will likely be affected by the weight of the snow."
The county has set up a hotline for residents dealing with issues like frozen pipes, roof problems and food shortages. The San Bernardino Mountains are a major tourism and recreation destination but also home to a large year-round population in small cities and communities around lakes and scattered along winding roads. About 80,000 people live either part- or full-time in the communities affected, said David Wert, a county spokesman.
Reprieve was on the way as the mountain community continued to dig out, with much of California expecting drier weather on Thursday.

"I woke up this morning and there was another two-and-a-half feet on them," he said. "It was kind of like Groundhog Day."
Residents of these towns are grappling with so much snow they're running out of space to put it; clearing one area adds heaps to another. Grocery shelves had run bare of some items, like bread, and were running low on eggs and milk Tuesday. Cars remained buried under snow and roads closed.
