(KGTV) - Gov. Jerry Brown issued a state of emergency as an aggressive wildfire in Mariposa County continued to burn tens of thousands of acres.
Brown declared the emergency Tuesday as the Detwiler Fire raged for its second day in the mountains just outside Yosemite National Park and sent thousands fleeing as evacuation orders were given.
The fire, which began late Sunday, has grown to about 70,000 acres and destroyed at least 45 structures, with about 1,500 structures threatened. Per Cal Fire, the blaze is 10 percent contained as of Thursday morning.
Cal Fire said more than 3,100 fire personnel were battling the blaze, including a strike team and two battalion chiefs deployed Tuesday from Rancho Santa Fe Fire and three engines from San Diego Fire-Rescue that were deployed Wednesday.
"Today we sent three of the five engines making up Metro Zone Type 1 structure engine strike team," San Diego Fire-Rescue chief Brian Fennessy said. "While our department and many other fire agencies within the region have resources assigned to fires north of our city, San Diegan's [sic] can rest assured that the level of emergency service in our communities remains constant and that if a significant fire(s) were to occur in the region which taxes the remaining local resources, the mutual aid system will be available to assist us in our time of need."
At least 400 engines, 56 different crews, at least nine air tankers, 14 helicopters, and 57 water tenders were fighting the Detwiler Fire.
Although it's unknown exactly how many San Diego firefighters were sent north to specifically fight the Detwiler Fire, 10News learned Wednesday 275 total fire personnel from San Diego County are currently deployed to battle 17 fires statewide.
San Diego Cal Fire alone has sent 17 engines and 181 firefighters. The agency has canceled days off for all of its firefighters and it's in the process of calling in extra personnel to staff local fire stations.
Ninety-four firefighters and 29 engines from other local fire agencies are also battling California wildfires.
