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

One of the fires burning now more than 100,000 acres in Rio Blanco County in northwest Colorado continues to grow during ongoing "near-critical fire weather" conditions.
