Wildfires have occurred in many parts of the U.S. this year, indicating the country faces another active fire season, said Tom Tidwell, head of the U.S. Forest Service. "We need to understand the conditions that we're facing today. They're different than what we used to deal with," Tidwell said. Long droughts "affect the fire behavior that we see, and the more erratic weather that we're seeing, especially throughout the country this spring, those are the things we have to factor in," he said.
