Severe storms that moved across the Midwest on Tuesday knocked out power to more than half a million customers in the Chicago area and northwestern Indiana, forced temporary halts at Chicago’s major airports and produced tornadoes and life-threatening wind gusts, officials said.
Widespread outages, damage and at least one fatality
The storm system swept from Iowa into Indiana over several hours, delivering violent straight-line winds, torrential rain and lightning that injured people in Ohio prison facilities. The National Weather Service said preliminary information indicated the intense, fast-moving system qualified as a derecho, a long-lived wind event capable of producing damage similar to tornadoes or hurricanes.
Two tornadoes were confirmed just south of Chicago Tuesday night, the weather service said. Social media and local reports showed flooded streets, downed trees tangled with power lines and homes with significant roof damage in communities across northeastern Illinois and into Indiana.
Injuries and disruptions across state lines
In Ohio, the storm left parts of the state capital region without power and officials reported at least one death. At the Grafton Reintegration Center southwest of Cleveland, lightning struck as incarcerated people returned from an evening meal, the Ohio Department of Corrections said. A department spokesperson said 16 incarcerated people were hospitalized, one by helicopter; their conditions were not immediately released.
Air travel was affected in Chicago, where all flights at both of the city’s major airports were temporarily halted while crews worked to clear a backlog and ensure safe operations, officials said. Forecasters warned travelers to expect delays as operations resumed.
“No power. It was very scary. We were down in the basement,”
That was how Homewood resident Javid Jenkins described the experience as the storm passed through his suburb south of Chicago. Jenkins, 54, said he went looking for fuel to run a generator to preserve food left refrigerated in his home following the outage.
Extreme wind reports and derecho classification
Meteorologists recorded a peak wind gust of 99 mph in Gary, Indiana. Numerous other reports indicated winds of at least 80 mph at private weather stations throughout the region. The Storm Prediction Center noted that the system’s characteristics — widespread, intense straight-line winds traveling long distances — matched those of a derecho.
Derechos can cause extensive damage to trees, structures and power systems because of their size and speed. The weather service issued urgent warnings earlier in the day, stressing the potential for life-threatening winds and rapid-onset emergencies.
Where impacts were reported
- Chicago area and northwestern Indiana: widespread power outages, property damage, two tornado touchdowns.
- Ohio: power outages in the state capital region; at least one fatality; multiple injuries from lightning at a prison complex.
- Air travel: temporary stoppage of flights at Chicago’s two major airports with expected delays as traffic resumed.
Emergency crews and utility workers were mobilized across affected counties to assess damage, restore electricity and clear roadways obstructed by debris. Officials urged residents to avoid downed power lines, stay clear of flooded streets and follow local emergency guidance.
| Item | Reported figure |
|---|---|
| Power outages | More than 500,000 customers |
| Peak wind gust | 99 mph (Gary, Indiana) |
| Tornadoes | 2 touchdowns south of Chicago |
| Prison injuries | 16 hospitalized |
| Reported fatalities | At least 1 |
Utility companies could not immediately provide full restoration timetables as crews worked to access heavily damaged areas. Residents were advised to report outages and downed lines to their local utility and to check official local channels for updates on sheltering and road closures.
As cleanup continues, meteorologists and public-safety officials warned that additional severe weather could complicate recovery efforts. The scale and speed of the event underscore the dangers posed by powerful convective systems and the need for swift, coordinated response when they strike densely populated regions.
