Catastrophic Flooding Sweeps Indiana and Neighboring States After August Derecho
8/13/2026, 4:08:01 AM
Core Event
On August 11–12, 2026 a line of severe thunderstorms and a rare, long-lasting derecho slammed the Midwest, dumping up to ten inches of rain in parts of eastern Indiana and northern Kentucky. The deluge triggered flash-flood emergencies across six Indiana counties—Wayne, Delaware, Fayette, Union, Franklin and Brownsville—forcing evacuations, flooding roads and homes, and causing multiple deaths. Power outages affected hundreds of thousands of customers, and emergency crews conducted dozens of water rescues.
Background & Context
The storm system followed a deadly derecho earlier in the week that produced hurricane-force winds across Illinois, Indiana and Ohio. Meteorologists note that a warming atmosphere can hold more moisture, increasing the likelihood of extreme rainfall events. The National Weather Service warned that saturated soils would amplify flash-flood risk as additional storms moved through the region on August 12.
Data & Statistics
- Rainfall totals: 6–10 inches in Wayne County, 5–8 inches in Cambridge City, and a 1-in-1000-year flood estimate in New Castle.
- Power outages: roughly 300,000 homes and businesses in Indiana and more than 700,000 across the broader region (PowerOutage.us).
- Fatalities: a 4-year-old boy killed in Geneva Township, Indiana; one person died in an explosion and house fire in Portage, Indiana; an additional death reported in Roseville, Ohio.
- Infrastructure damage: State Road 38 washed out west of U.S. 35 in Wayne County; a newly built road collapsed in New Castle.
Official Statements & Responses
Indiana Governor Mike Braun directed state agencies to work “around the clock” with local officials and utility crews, emphasizing resource deployment and public safety. Ohio Governor Mike DeWine declared emergencies in Perry and Muskingum counties and activated a National Guard high-water rescue unit. INDOT Commissioner Lyndsay Quist confirmed crews were closing roads and addressing flood-related damage, while ISP Superintendent Anthony Scott warned motorists to avoid flooded roadways. Local emergency managers in Delaware, Fayette and Wayne counties issued evacuation orders and travel watches, urging residents to “turn around, don’t drown.”
On-the-Ground Reports
Fire departments in Muncie went door-to-door to evacuate residents, and public buses with high clearance were used in New Castle to transport evacuees. Residents in Cambridge City described streets submerged under “murky, brown water,” with a school bus half-underwater and homes completely underwater. Water rescues in Fayette and Wayne counties involved boats retrieving stranded motorists, including a FedEx driver and a driver forced onto his SUV’s hood. In Portage, police noted that downed trees likely damaged natural-gas lines, contributing to the fatal explosion.
Conflicting Reports & Gaps
Outage figures differ: CNN cited nearly 300,000 Indiana customers without power, while PowerOutage.us reported over 700,000 across the region. Fatality counts also vary; some outlets listed only the child’s death, whereas others added the Portage explosion and the Roseville casualty. No definitive cause has been confirmed for the Portage explosion, and investigations into the Roseville death remain ongoing.
What’s Next
The NWS forecast continued heavy rain through Thursday, with the risk of additional flash-flood emergencies in Indiana, Ohio and Kentucky. Travel warnings remain in effect, and Indiana officials have extended the state of emergency through at least August 13. Governor Braun reiterated that residents should heed road closures, avoid driving through water, and stay informed via multiple alert channels.
