The fires have again renewed focus on dangers in what it known as the wildland-urban interface or WUI, where fire has marched into urban areas in both California and Colorado with greater losses than ever in recent years.

Firefighters from the Colorado Springs Fire Department (CSFD) completed their first 24 hour shift fighting the wildfires in Los Angeles.

Fire crews and equipment from around the Front Range are now in California to help with the wildfires. The state also sent a specially designed plane.
