Most of the Colorado mountains will see red flag warnings on Sunday, including Aspen

Much of Colorado will have to endure critical fire conditions and continued 100 degree weather as the heat wave peaks Sunday before temperatures begin to cool later this week. 

The National Weather Service issued a red flag warning, signaling high fire danger, for parts of the Front Range and much of the mountains due to the hot, dry air. Meteorologists said conditions are favorable for rainless thunderstorms in affected areas. Low humidity and gusty winds could quickly spread any flames caused by lightning strikes. 

The warning impacts Fort Collins, Aspen, Telluride and more. 

Residents in affected areas are encouraged to avoid activities that could produce a spark. The red flag warning is set to expire at 9 p.m. on Sunday.
