On August 11, 2026, Indiana Governor Mike Braun issued a statewide disaster emergency order following a derecho that produced tornadoes, wind damage, and flooding across northern Illinois, northwest Indiana, and parts of Iowa. The storms led to the largest outage event in NIPSCO history and affected power supply to 540,000 homes across the Midwest, with flood watches remaining in effect. Sources from ABC News and The New York Times confirm the sequence of severe weather, tornado touchdowns, and ongoing outages but provide no data on fatalities or insured losses.
