A fire raging on the Oregon-California border, which has been dubbed the Caldwell Fire has been pushed by winds from a thunderstorm, and has more than doubled in size. The fires were sparked by lightning on Wednesday of last week. One of our writers for That Oregon Life lives just 25 miles from where the fires are raging.

Sources say outflow winds from a thunderstorm Sunday caused the Caldwell Fire to spread seven miles to the north. As of early Sunday morning the fire was said to have burned 13,125 acres, but at 12:20 a.m. Monday a fixed wing aircraft mapped it at 43,749 acres, an increase of 30,624.

On Monday firefighters on the north side of the fire are focused on protecting structures in the Tulelake area and construct both direct and indirect containment line. At this time, it’s been reported Tulelake is half under mandatory evacuation right now. Tionesta, just south of the fire has already been evacuated.
