A fast-moving fire engulfed several homes Tuesday in Colorado as firefighters battled strong winds, officials said.

Two homes were completely destroyed and three others damaged by the blaze reported around 10 a.m. in Castle Rock, according to news station KCNC. Authorities said no one was harmed.

Surrounding homes were evacuated and the fire has since been contained.

“When this fire came in we had consistent 30- to 40-mile-per-hour winds in the area and we had a lot of our resources south for [another] fire,” Castle Rock Fire Chief Art Morales told the news station.

It’s unclear what caused the fire, but officials suspect the blaze started in a garage.

“The garage door was open, we believe that’s what helped the fire move into the home,” Morales said.
