MOFFAT COUNTY, Colo. Firefighters are working to protect some ranches from the largest wildfire currently burning in the state of Colorado.

The Peekaboo Fire is burning 44 miles northwest of Maybell, near Dinosaur National Monument. The fire, which was reported to be 12,675 acres in size Saturday night, spread to over 19 square miles after winds pushed it in several directions. So far, about five percent of the fire has been contained.

A Temporary Flight Restriction is still in place to allow fire crews on the air to fight the fire safely.

Thunderstorms are expected to move into the area Sunday afternoon.

The Peekaboo Fire, which has been burning for nearly two weeks on Cold Springs Mountain north of Browns Park National Wildlife Refuge, was started after lightning struck in the area. A total of 267 firefighters are working to put out the blaze.
