A Colorado prison was evacuated as one of the largest wildfires in state history continued to grow, and officials warned residents of remote areas to be ready to leave Sunday as gusty winds and low humidity fed the flames.

New mandatory evacuations were ordered in the Lee fire late Friday night and early Saturday morning as the blaze grew nearly 30,000 acres on Colorado’s Western Slope near Meeker.

The Moffat County Sheriff's Office on Sunday afternoon issued pre-evacuation orders for some parts in the northwest Colorado city of Craig, due to a wildfire that grew in the area.
