East Fork Fire says a nearly 280-acre brush fire south of Carson City near Genoa Lakes is 100% contained as of Wednesday. 

Fire officials say they believe the fire was started by construction equipment working on a new home.

Douglas County Sheriff says voluntary evacuations in the James Canyon Loop neighborhood have been lifted.

No structures have been lost in the fire so far.

The county also says it closed its voluntary evacuation centers around 9 p.m. Monday. 

Douglas County Sheriff says 20-30 structures were threatened and 100 personnel are on scene.

Meanwhile, the fire threat remains high, and the Truckee Meadows is anticipating a number of Red Flag days. 

“We strongly encourage our residents to refrain from any activity that could spark a wildfire, to include target shooting,” said Fire Chief Charles Moore.  Target shooting is the suspected cause of at least two brush fires that occurred over the weekend.

This week’s weather forecast calls for lightning strikes Wednesday through Friday. “A majority of natural caused fires are triggered by lightning,” said Chief Moore. “Given our current weather conditions coupled by lightning strikes, we continue to ask our residents to be vigilant and report smoke by calling 911, and take prudent action to protect you and your loved ones from lightning strikes.”

If you hear thunder, you are within striking distance of lightning.  Look for shelter inside a home, large building, or a hard-topped vehicle right away.  Do not go under trees for shelter.  There is no place outside that is safe during a thunder and lightning storm.
