Fire crews will continue to monitor overnight the 542-acre McNay fire, burning 10 miles west of Livermore, as it reached 77 percent containment Monday evening, according to the Larimer County Sheriff’s Office.

Authorities have lifted all voluntary evacuations and all roads are open, according to a sheriff’s office news release. Poudre Valley REA employees plan to work on power lines in the fire zone Tuesday, the sheriff’s office said.

No structures were damaged and no one has been injured.

Aircraft resources were deployed to assist in battling the fire about 30 miles northwest of Fort Collins, after it started from a car fire and grew Sunday.

About 130 firefighters, five aircraft and a bulldozer worked on the wildfire Monday, with as many as 11 aircraft used at different times Sunday, the sheriff’s office said early Monday.

Ground fire crews plan to return Tuesday morning to continue battling the fire, according to a sheriff’s office news release.

Hot, dry and windy conditions have contributed to wildfires across the state over the past couple of weeks.

The Decker fire about 9 miles south of Salida, ignited Sept. 8 by lightning, spread to 846 acres, according to the National Wildland Fire Coordinating Group incident system.

The Hunt fire, sparked by lightning Sept. 5 in Rio Blanco County in northwest Colorado, is at an estimated 3,766 acres and is 40% contained, according to the incident system.

The Middle Mamm fire, 60 miles southwest of Denver near Shawnee Peak, also was started by lightning July 28 and is burning in the Middle Mamm Creek drainage about 10 miles south of Rifle, at an estimated 275 acres, according to the system.
