Firefighters prevented any growth of the 8,838-acre Red Bank Fire west of Red Bluff in Tehama County Sunday.
The fire broke out Thursday afternoon, according to Cal Fire. It was 50 percent contained as of 8:30 p.m. Sunday.
Cal Fire reported that the fire is burning in a remote location that's difficult to access and that multiple structures are threatened. The fire was caused by lightning strikes in the area.
The weekend brought cooler temperatures, higher humidities and light winds, which is assisting in the firefight, though large amounts of dry vegetation remain in the area. Cal Fire is anticipating those conditions will hold into Monday morning.
All mandatory evacuations and evacuation warnings have been lifted.
Another fire burning in the area south of Platina, called the South Fire, had grown to 2,050 acres Saturday morning with no containment.
This is a developing story. We will provide more information as it becomes available.
