KUSA - It was 58 degrees at the high point on Saturday, with winds gusting 30 miles an hour. Even a small spark from a power line quickly covered a lot of ground.
A clear day made the dark smoke coming from the largest of the fires easy to see.
Firefighters believe power lines started two fires in Thornton. One occurred near 139th and Quebec Street. A a smaller fire burned near Quebec Street and E-470.
It's not clear what started another fire near County Roads 6 and 13 in Weld County. No structures were burned.
The fires in Thornton burned a storage shed and a water pump. The area burned is open land, but very close to a neighborhood where people were relieved fire crews stopped it as fast as they did.
The Thornton fire caused a brief power outage in the neighborhood. No homes were damaged.
