Wildfires were devouring large swaths of Oklahoma like a hungry beast Thursday as firefighters struggled to douse the flames. Feeding on vegetation parched by drought and stoked the 50 mph winds, the fires in Oklahoma have merged into one huge inferno dubbed 350 Complex Fire that has already consumed 57,440 acres."It’s been very active," said Hannah Anderson of Oklahoma Forestry Services. "We have only a 20 percent containment. We’ve had very strong winds, very low humidity... the perfect recipe for fire behavior." Several firefighters have been hospitalized because of heat exhaustion, Anderson said.
