Crews try to keep massive northern Nevada wildfire at bay

Firefighters in Nevada are hoping to stop a wind-driven wildfire that has already destroyed 22 homes north of Carson City from jumping any major roads.

Fire officials say the blaze burning in the Washoe Valley near Interstate 580 and U.S. Highway 395 between Reno and Carson City was 5 percent contained Saturday morning.

The fire has now grown to more than 5 square miles and 500 structures remain threatened.

The Sierra Front Interagency Fire Dispatch Center reports there are now 855 personnel working on the wildfire. Seven air tankers have been deployed.

The fire was first reported shortly after 1:30 a.m. Friday.

Crews say rain somewhat helped moderate fire activity, but strong winds have been forecast for later in the day.

The cause is still under investigation.
