By Hollie Silverman and Joe Sutton, CNN Oregon’s fierce Bootleg Fire has destroyed more than 400 structures and 340 vehicles since it began three weeks ago, officials said Tuesday. The blaze has grown to 410,731 acres and remains at 53% contained, according to an Inciweb update. The Bootleg Fire has destroyed 161 residences and 247 outbuildings. Cooling temperatures and the likelihood of isolated showers through Wednesday are expected to help the fight. But aggressive fire behavior is expected to return later in the week as temperatures rebound and rise, according to Inciweb.
