Minnesota wildfires continue burning, officials warn this could last 'all summer'

Firefighters continue battling wildfires across northeastern Minnesota, where more than a dozen active fires, collectively known as the July Lightning Event, have burned an estimated 77,000 acres in and around the Superior National Forest and Boundary Waters Canoe Area Wilderness. Air quality is improving across much of Minnesota as wildfire smoke shifts north on Friday, but hazardous air quality is expected to persist across northeastern regions through the weekend. Officials gave an update on Friday afternoon, warning that the wildfires could last all summer, or until there is a significant change in ongoing weather patterns.
