Wildfire season is off to an intense start with fast-moving flames tearing through thousands of acres across the western U.S. Dry conditions and extreme heat are fueling massive blazes, prompting evacuations and destroying historic landmarks. Several fires have already reached tens of thousands of acres, including one that has been burning for nearly a month. Air quality alerts are in effect for millions as smoke drifts across state lines. Officials warn this wildfire season may be longer and more dangerous than usual.
