‘Catastrophic’ Flooding Engulfs Indiana as Midwest Storms Rage On
Monster Storms Drown the Midwest: What’s Happening in Indiana, Ohio, and Beyond
Published: August 12, 2026 | Updated: August 13, 2026
Region Affected: Indiana, Ohio, Illinois, Kentucky, and parts of the Appalachians
The Big Picture: A Week of Non-Stop Storms
Imagine a garden hose left running on full blast over the same patch of grass for days. The ground gets so soaked it can’t hold any more water—so it turns into a swamp. That’s basically what’s happening across the Midwest right now.
Since Sunday, wave after wave of thunderstorms has hammered the region. By Wednesday, eastern Indiana got more than three months’ worth of rain in just 36 hours. Rivers are overflowing, roads are washing away, and hundreds of thousands are without power.
The storms aren’t done yet. Forecasters say the threat could last through Friday.
What’s Happening Right Now (Wednesday Update)
Flash Flood Emergencies – The Highest Alert
- 7 counties in eastern Indiana are under a Flash Flood Emergency—the most serious warning the weather service issues.
- In Muncie, firefighters went door-to-door telling people to leave immediately.
- Nearly 300,000 homes and businesses in Indiana have no electricity.
Towns Underwater
| Town | What Happened |
|---|---|
| Cambridge City | Water past window level, cars nearly submerged, boil-water advisory, utilities may be out for days |
| New Castle | 11+ inches of rain in 32 hours — a “1-in-1,000-year flood” (0.1% chance any given year). Waist-deep water. City buses used to evacuate people. |
| Muncie | ~200 homes evacuated, boat rescues, first day of school canceled |
Governor’s Response
Indiana Gov. Mike Braun: “Multiple roads washed out… a lot of water rescues… a statewide emergency declaration is likely.”
Tuesday’s Deadly Derecho: What Is That?
ELI5: A derecho (deh-RAY-cho) is like a hurricane’s windy cousin that lives on land.
It’s a long-lasting, straight-line windstorm that travels hundreds of miles, knocking down trees, power lines, and buildings. Unlike a tornado (which spins), a derecho pushes forward in a line.
Tuesday’s derecho:
- Swept across Illinois, Indiana, and Ohio
- Killed at least 3 people:
- A 4-year-old boy in Indiana (tree fell on house)
- One person in Portage, Indiana (possible gas explosion after trees damaged lines)
- One person in Ohio (emergency, rescuers couldn’t reach in time)
- 16 inmates hospitalized in Ohio after lightning struck a prison (7 still in hospital)
- NIPSCO (Indiana utility) reported its largest outage in company history
Ohio Gov. Mike DeWine declared emergencies in Perry and Muskingum counties and sent in the National Guard for water rescues.
What’s Coming Next? (Thursday–Friday)
Highest Risk Areas
- Northern Kentucky upgraded to Level 3 of 4 flood risk
- Illinois, Indiana, Ohio – more flooding rain Thursday
- 4 river gauges in eastern Indiana expected to hit major flood stage
- Appalachians & central U.S. – continued threat
Rainfall Rates Could Be Extreme
- Up to 3 inches per hour in spots
- 5+ inches total where storms “train” (repeat over same area)
- Even less rain causes flash floods because the ground is already saturated
Severe Storm Threat Wednesday Evening
- Damaging winds possible (but not as bad as Tuesday’s derecho)
- More tree falls & power outages likely
Why Is This Happening? The Climate Connection
Warmer air = bigger sponge.
As the planet warms from burning fossil fuels (coal, oil, gas), the atmosphere holds more moisture. Storms tap into that extra fuel and dump more rain in shorter bursts.
Scientists say these “1-in-1,000-year” floods are becoming less rare—because the baseline has shifted.
How to Stay Safe: 5 Steps Right Now
- Never drive through floodwater — 6 inches can knock you down, 12 inches floats a car. Turn around, don’t drown.
- Charge devices & prep flashlights — power may be out for days.
- Follow local evacuation orders immediately — don’t wait.
- Boil water if advised — Cambridge City and others have advisories.
- Check on neighbors — especially elderly or disabled folks.
IMPORTANT: If you’re in a warned area, get to higher ground NOW. Flash floods move faster than you think.

FAQ: Your Questions Answered
Q: What’s the difference between a flood watch, warning, and emergency?
A:
- Watch = conditions could lead to flooding (be ready)
- Warning = flooding is happening or imminent (take action)
- Emergency = catastrophic, life-threatening flooding (get to high ground NOW)
Q: What does “1-in-1,000-year flood” actually mean?
A: It means there’s a 0.1% chance of that much rain happening in any given year under normal conditions. But “normal” is changing—these events are happening more often now.
Q: Why can’t I just drive through a little water on the road?
A: Water hides washed-out roads, debris, and currents. Just 12 inches can float a small car. Turn around, don’t drown.
Q: How long will power be out?
A: In hardest-hit areas, days. Utilities call this a “largest outage in history” event. Have batteries, water, and non-perishable food ready.
Q: Is this storm system over?
A: Not yet. Thursday brings another round of heavy rain to the same soaked ground. Friday may see the threat shift north to the Upper Mississippi Valley.
