The Dragon Bravo Fire in Arizona has destroyed dozens of structures and a water treatment facility on the Grand Canyon's North Rim.

A combination of high winds, dry air and above average temperatures caused a wildfire in the Grand Canyon to rapidly expand and cause major damage.

A fast-moving wildfire near the Grand Canyon’s North Rim has destroyed the historic Grand Canyon Lodge and dozens of other structures, triggered a chlorine gas leak, and forced widespread evacuations.

A mix of high temperatures, gusty winds, low humidity, and dry vegetation has fuelled the fire's swift advance in Arizona, officials say.

Abnormally dry, hot conditions near the Grand Canyon's North Rim allowed the Dragon Bravo Fire to grow rapidly.

On Friday morning, the NWS office in Flagstaff, Arizona, issued an extreme heat warning for Grand Canyon Village, North Rim and Supai. The warning is in effect for areas below 4,000 feet in elevation. The warning specifically addressed hikers and urged them to use caution.
