A wildfire close to Meeker in western Colorado has doubled in size. The Lee Fire west of the historic town has now burned an estimated 45,000 acres and so far firefighters don't have any containment on it.

Two lightning-sparked wildfires burning near Meeker in Rio Blanco County had scorched 45,000 acres and 14,250 acres, respectively, as of Wednesday evening, fire officials said.

In a Wednesday afternoon update, the Rio Blanco Sheriff's Office said the Town of Meeker was under a pre-evacuation notice due to "the potential for the fire to jump," while residents in areas southwest of Meeker were ordered to evacuate immediately.
