Illinois has confirmed 210 tornadoes so far in 2026, according to the National Weather Service office in Romeoville, marking the most twisters documented in a single year for the state and putting it within range of the U.S. single-state record.
Record numbers across the state
The tally of 210 tornadoes through Aug. 29 eclipses Illinois’ previous high of 142, set in 2024, and stands well above the National Oceanic and Atmospheric Administration’s long-term average of 66 tornadoes per year for the state. The count includes several tornadoes tied to the Aug. 11 derecho that struck parts of northeastern Illinois, including suburbs on Chicago’s south side.
Meteorologists note that only one state has surpassed 200 tornadoes in a year since reliable records began in 1950: Texas, which logged 244 tornadoes in 2015. With Illinois now over 200 tornadoes in less than eight months — despite having roughly one-fifth the land area of Texas — forecasters say it is possible the state could continue to add to its total into the fall and early winter.
What the numbers mean locally
For residents and local officials, the figures are more than statistics. Communities that have already dealt with multiple tornadoes this spring and summer face ongoing recovery and heightened preparedness needs. Emergency management agencies are assessing damage, prioritizing repairs and reminding residents about storm readiness, including safe rooms, evacuation plans and keeping emergency kits accessible.
- Confirmed tornadoes (Illinois, 2026 as of Aug. 29): 210
- Previous Illinois record: 142 (2024)
- NOAA yearly average for Illinois: 66
| Statistic | Figure |
|---|---|
| Illinois tornadoes, 2026 (Aug. 29) | 210 |
| Previous Illinois record | 142 (2024) |
| Texas single-state record | 244 (2015) |
How this compares nationally
Historical severe-weather archives show several large tornado years for Texas, including the 244 in 2015 and other years topping 200. No other state besides Texas had reached more than 200 tornadoes in a single year before Illinois’ surge in 2026. Tornado-prone states such as Kansas, Oklahoma and Alabama have not recorded totals this high in a single year.
Forecasters caution that tornado activity in Illinois is not strictly limited to spring and early summer. The state can experience tornadoes into the fall and occasionally in early winter, meaning this year’s tally could increase before the season ends.
Local context and next steps
Communities affected by tornadoes are continuing damage assessments and recovery operations. Local officials and the National Weather Service are urging residents to:
- Review and update family emergency plans.
- Identify the safest place in a home or building (an interior room on the lowest floor away from windows).
- Keep weather radios or smartphone alerts enabled for watches and warnings.
State and local emergency management agencies will also be monitoring conditions and coordinating resources where needed. The National Weather Service in Romeoville continues to conduct post-storm surveys to confirm tornado tracks and intensities, and the confirmed counts are updated as those surveys are completed.
Meanwhile, neighboring states are also reporting unusual tornado activity. Preliminary information indicates that Indiana has surpassed its prior yearly total as well, though official tallies are still being finalized.
As the calendar moves into the latter part of the year, Illinois residents and officials will be watching both the weather and ongoing damage assessments closely. Updated storm counts and maps are posted periodically by the NWS and NOAA as post-event surveys conclude.
