Firefighters are concentrating on the Boulder fire burning five miles south of Wellington which expanded to 200 acres during the night, according to the latest report from the Sierra Front Dispatch.
The brush and grass fire grew quickly Friday night burning to within a mile of structures. Five air tankers four hand crews, three helicopters and more than 200 firefighters are fighting the fire.
The fire was active throughout the night in rough terrain, according to Fire Information Officer Mark Struble. The terrain is hampering firefighters' efforts to build lines around the fire.
An incident management team took over command of firefighting efforts this morning. They are based out of Smith Valley High School.
As of this morning, there have been no closures or evacuations as a result of the fire.
Meanwhile, firefighters have a line 30 percent of the way around the Pine Nuts fire, located 9 miles east of Johnson Lane in Douglas County.
Hand crews worked throughout the night to cut that line around the fire.
Struble said they'll be improving the line today with the hopes of full containment by tonight. He said trees inside the lines may burn, causing intense smo0ke.
So far the only damage from either fire, besides the vegetation, is a NV Energy transformer and possibly some transmission lines. NVEnergy has a crew on the scene to assess and repair any damage.
Officials aren't listing the cause of either fire, but a thunderstorm cell traveling north along the Douglas-Lyon county line coincided with their ignition. There's a chance for dry lightning storms again today. Wind gusts of 20 mph could accompany the storms, hampering firefighters' efforts.
