Update: The next set of storm cells traveling through the Pine Nut Mountains has prompted a flash flood warning from the National Weather Service.
The warning was issued at 5:28 p.m. after radar indicated a thunderstorm 13 miles east of Johnson Lane moving west at 5 mph. Heavy rain from the storm will affect the west slope of the Pine Nuts, with runoff possibly reaching upper Johnson Lane.
The warning is in effect until 7:30 p.m.
A 100-acre brush fire is burning in the Pine Nut Mountains about seven miles east of East Valley Road.
The fire is located in a remote location, preventing engines from reaching the blaze, according to East Fork Fire Marshal Steve Eisele.
"It's tough to get to," Eisele said. "There is no road access."
Two helicopters were dousing flames as hand crews hiked up to the blaze.
No structures are threatened by the fire. A group conducting a camp-out retreat in the mountains is out of harm's way. The fire is moving downslope north at a moderate rate, Dispatcher Helen Frazier said. More than 100 personnel are working the fire. There is no estimate of containment or control.
The Spring fire and three others, was set by lightning at about 2 p.m. One of the fires located in an old burn went out on its own.
"I don't know if it got a little rain or ran out of fuel, but it's out," Eisele said.
The other three fires are close together in remote location near Buckeye Canyon.
According to the Sierra Front Interagency Dispatch, the fire is in Bureau of Land Management jurisdiction.
In addition to the BLM, East Fork Fire District, Nevada Division of Forestry and U.S. Forest Service firefighters are battling the blaze.
A red flag warning is in effect until 5 a.m. Monday for thunderstorms and strong outflow winds, according to the National Weather Service. Fast storms will create isolated to scattered dry thunderstorms. The storms started south of Highway 50, but are expected to spread further north tonight. Lightning may start new fires which will grow quickly due to strong outflow winds.
