The Junction Fire in Madera County ignited around 2 p.m. on Monday, and has already burned through 1,200 acres.
According to CAL FIRE, the Junction Fire, near Highway 41 and Highway 49 in Oakhurst, has already destroyed 8 structures and threatens another 500.
Firefighters are struggling to establish containment lines because the main fire has many nearby spot fires and the weather is windy.
According to the Sacramento City Fire Department, firefighters from Sac City Fire, Cosumnes Fire Department, and Folsom Fire Department have assembled a strike team to head to the Oakhurst fire.
Several other firefighters from throughout the Central Valley are going to assist with defending homes threatened by the fire.
