DENVER (Reuters) - Firefighters battling several unrelenting wildfires in the U.S. Southwest will face windy and dry weather on Friday before possibly getting a reprieve over the weekend, when widespread showers and thunderstorms are forecast.
Red flag warnings are in effect for southern Nevada, southern Utah and western Colorado, where winds gusts could reach 45 miles (72 km) an hour and humidity could reach around 10 percent on Friday, the National Weather Service said.
Although the wet weather could help efforts to battle two dozen wildfires that are currently burning in the region, it could also cause flash floods, the National Weather Service added.
The largest and most threatening blaze is the 416 Fire, which has scorched nearly 33,000 acres (13,000 hectares) of drought-parched grass, brush and timber at the edge of the San Juan National Forest near the southwestern Colorado town of Durango.
Fire officials said on Friday that crews had contained 18 percent of that blaze.
Efforts have at times been stalled or shut down entirely as people persist in sending aerial drones toward the flames, presumably in the hope of capturing spectacular pictures and videos of the inferno, according to the Bureau of Land Management in Colorado.
The drones endanger the safety of pilots flying tankers and helicopters to battle the fire, the BLM's Steve Hall told the Denver7 news station.
Officials lifted evacuation orders for some 375 residences and 19 businesses in the area. Nearly 1,000 residences and businesses remained under evacuation orders, La Plata County officials said.
The 416 Fire and a separate, smaller blaze burning nearby, the Burro Fire, prompted state parks officials to close several wildlife areas to the public. The U.S. Forest Service has closed all 1.8 million acres of the San Juan National Forest to visitors.
About 60 miles west of Denver, evacuations from 1,400 homes were lifted on Thursday near the 81-acre Buffalo Fire as crews gained 45 percent containment around the blaze, fire officials said.
No one has been injured and no structures have been lost in the Colorado fires, but nine homes were destroyed in a small wildfire in Utah.
In southern Wyoming near the Colorado border, the Badger Creek Fire in Medicine Bow National Forest has grown to more than 11,100 acres, according to the Inciweb online U.S. fire information service.
The Wyoming fire containment was listed as zero percent by fire officials. About 400 homes in Albany County have been ordered to evacuate.
