The Southern Arizona Chapter of the American Red Cross will be deploying four volunteers to Northern California shelters to help residents displaced by an ongoing wildfire.
The volunteers planned to leave Monday.
The deadly Carr Fire has forced tens of thousands of people to flee their homes.
The fire grew slightly Sunday to 139 square miles.
It's the largest fire burning in California, threatening more than 5,000 structures.
The latest tally showed at least 517 structures destroyed and another 135 damaged.
