Strong winds and hot, dry weather continue to fuel two separate wildfires near the northwestern side of the Grand Canyon Saturday, closing the canyon’s North Rim and forcing evacuations throughout the area.

Wildfires have forced evacuations at two U.S. national parks in the West as summer monsoon storms increase lightning in the region.

A Grand Canyon water treatment facility located at the North Rim caught fire on Saturday, causing chlorine gas to be released into the air. Multiple closures are being enforced due to the incident.

About 10 people die at the Grand Canyon every year, CBS affiliate KPHO reported. This is the second death at the park that the park service has reported this year. In May, a 74-year-old man died while attempting to hike from the canyon's South Rim to the North Rim, an approximately 24-mile distance.
