Firefighters and aircraft worked Tuesday to halt the spread of two forest fires in rural northeastern California as unstable weather brought the risk of gusty winds, thunderstorms and lightning strikes that could start new blazes.
The Gold Fire in northern Lassen County nearly doubled in size to 7 square miles (18.2 square kilometers) south of the tiny Modoc County community of Adin and there was no containment.
Two firefighters were injured at that blaze Monday and were flown to a hospital in Redding but there were no details on their conditions or what happened, said Alisha Herring, spokeswoman for the California Department of Forestry and Fire Protection.
Herring said damage to a fiber optic cable was interfering with communication.
In southern Lassen County, the Hog Fire covered 12.5 square miles (32.4 square kilometers) about 5 miles (8 kilometers) from the town of Susanville and was just 5% contained. The size of the fire was reduced from earlier reports after improved mapping, Cal Fire said.
About 170 buildings were threatened and some evacuations were in effect.
In central California, the week-old Mineral Fire was 68% contained after scorching 44.5 square miles (115 square kilometers) and destroying seven structures in the Diablo Range west of Coalinga.
Several smaller wildfires burned elsewhere.
