The lightning started Big Red Fire increased dramatically over the last few days, growing from 600 to 1,400 acres. An unidentified drone flew over the burn area over the weekend, violating temporary flight restrictions and forcing helicopters working the fire to be grounded for two hours. Incident Commander Tom Roerick says that drones over fires pose a significant threat to pilots, crews and operators, so drone pilots should respect all flight restrictions, or face potential fines. The Big Red Fire, burning 5 miles south of the Wyoming State line, has forced the closure of multiple forest roads and trails in the area, for more information, click here.
