The latest wildfire in California has begun threatening homes in the Wofford Heights area in southern Sierra Nevada.
Several buildings have been reported ablaze and helicopters have been sent to dump water on the area.
Local news said the fire covered about 700 acres. Evacuation plans are on standby for nearby residents
Earlier this month three firefighters were trapped and had to deploy personal fire shelters as a rapid wind shift sent a Northern California wildfire burning over their location.
All three survived with no serious injuries.
