Crews have started to contain a wildfire in the Sierra Nevada foothills that destroyed more than 30 homes as it spread perilously close to neighborhoods in Reno, Nevada. Containment reached 27% and there was no new growth of the blaze, which has held steady at about 23 square miles since Sunday. Officials said Monday afternoon that the number of residents under evacuation orders and warnings was reduced to about 63,000, down from more than 90,000 people over the weekend. There’s still concern that winds could push the flames through dry brush into newly developed and densely packed neighborhoods in Nevada’s largest city outside of metro Las Vegas.

Officials say a fast-growing wildfire in Reno, Nevada, was human-caused. The Hawk Fire grew Sunday and is uncontained. Some 42,000 residents have been ordered evacuated and another 45,000 encouraged to leave so that firefighters can reach hot spots more easily. Authorities confirmed several structures have been destroyed and that six people have been hurt. Gov. Joe Lombardo declared a state of emergency in Washoe County and mobilized the Nevada National Guard to support aerial firefighting and protect neighborhoods from unauthorized visitors. Authorities said that altogether more than 1,000 people are responding to the fire.
