A Chicago-size wildfire in Alaska's Kenai Peninsula expanded to 243 square miles over the holiday weekend, prompting the evacuation of more than 1,000 structures.
The Funny River Fire, named for a nearby road, began on May 19 and is just 30 percent contained as Monday evening. State troopers are going door-to-door asking residents to leave homes and belongings that may be harm's way.
Michelle Weston, a spokeswoman for the Alaska Interagency Incident Management team, told the Associated Press that high winds and dry conditions are contributing to the fire. Although it is not unusual to see early-season wildfires, the size and speed of the Funny River Fire are both above average.
