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.

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

The White Sage Fire in Kaibab National Forest and the Dragon Bravo Fire near Grand Canyon National Park. The White Sage Fire, which started on July 9, has already scorched more than 20,000 acres of land and has not yet been contained, authorities said.

Hurricane Valley firefighters have been deployed to the White Sage Fire, which is exhibiting “extreme fire behavior” as it covers over 40,000 acres near Grand Canyon.

Officials evacuated Jacob Lake and the North Rim of the Grand Canyon was closed to visitors because of the fast-moving White Sage wildfire.

Mandatory evacuation orders issued for Grand Canyon's North Rim as White Sage Fire burns 1,000 acres, with Highway 89A closed and officials warning of extreme heat.

The Grand Canyon’s North Rim in Arizona also closed Thursday because of a wildfire on adjacent Bureau of Land Management land near Jacob Lake. The Coconino County Sheriff’s Office said it helped evacuate people from an area north of Jacob Lake and campers in the Kaibab National Forest nearby.

Hundreds of visitors and residents were evacuated from the North Rim of Grand Canyon National Park this week as two wildfires advanced toward the park.

A wildfire that's burning in the southern part of Black Canyon of the Gunnison National Park has grown to more than 1,600 acres.
