Wildfires are raging through areas of Colorado state in the USA, forcing 32,000 people to flee their homes.
800 firefighters are fighting the huge blazes. There are also fires in Montana, Wyoming, New Mexico, Arizona, California and Utah.
A huge fire that began in a canyon near Colorado Springs on Saturday is being fanned towards the city by 65mph winds.
Resident Hillory Davis said: "It took us an hour to drive a mile because of the traffic. It was really tense."
"The ash was falling out of the sky. We couldn't see the street because of the smoke."
Just weeks into the annual wildfire season there are also fires in Montana, Wyoming, New Mexico, Arizona, California and Utah.
The dry, hot temperatures are expected to continue across much of America this week, with little chance of rain.
President Barack Obama plans to visit the affected areas on Friday.
