Fire crews are facing dire challenges, hurdles that have intensified the fires and are complicating the response

As multiple fires rage around the Los Angeles basin, the 7,500 fire and emergency personnel on the ground are facing unprecedented conditions.

At least five LA residents have been killed, and the death count is expected to rise as responders search burned areas. At least 10,000 structures have been destroyed, and several of the five blazes are still burning out of control.
