8/14/2026, 11:12:46 PM
Core Event: Derecho and Multiple Tornadoes Strike South Suburbs
On Tuesday, the National Weather Service confirmed a rare derecho swept across the Chicago metropolitan area, spawning tornadoes. An EF2 tornado traveled from Monee to Crete, an EF1 from Orland Park to Flossmoor, and a third EF1 in Will County near Mokena. Additional tornadoes touched down in northwest Indiana, including EF2es in Munster and St. John. Winds gusted up to 80 mph and hail accompanied the severe thunderstorms.
Background & Context
The region had already endured severe storms earlier in July. Forecasts from the Storm Prediction Center had placed much of northern Illinois and northwest Indiana under an enhanced Level 3 of 5 risk for damaging winds, large hail, and brief tornadoes.
Data & Statistics
- Tornadoes: At least three confirmed EF-1/EF-2 tornadoes in Illinois; additional EF-2 tornadoes in Indiana.
- Wind: Gusts up to 80 mph.
- Power Outages: Over half a million customers lost electricity; roughly 3,000 ComEd employees and contractors were deployed.
- Fatalities: One death in a house explosion linked to the extreme weather in northwest Indiana.
- Economic Relief: SBA disaster loans allow homeowners up to $500,000, renters $100,000, and businesses $2 million. Application deadline is May 5 2027.
Impact
The storms ripped trees, toppled power lines, and damaged roofs at schools, churches, and homes. Marian Catholic High School lost power and roof integrity, canceling activities. Homewood-Flossmoor High School sheltered 250 students. In Portage, power loss contributed to food and gasoline shortages; the Salvation Army and Portage High School distributed meals and water. Daycare operations in Tinley Park were halted, forcing families to use vacation or sick leave. Generators operating inside garages raised safety concerns, prompting Crete Police Chief Scott Pieritz to issue a public warning.
Official Statements & Responses
Indiana Governor Mike Braun declared a statewide disaster emergency and mobilized the National Guard. ComEd’s executive vice president and COO David Perez said crews and equipment had been pre-positioned, yet damage remained extensive. The SBA outlined loan eligibility and procedures. The NWS continued flood warnings for Cook County rivers through Saturday and warned of additional severe-weather risk over the weekend.
On-the-Ground Reports
Power lines tangled with trees ignited a house fire in Frankfort, and downed lines sparked a grass fire in Oswego. Families reported spoiled food, loss of income, and the psychological toll of repeated storms.
Conflicting Reports & Gaps
- Tornado Count: ABC 7 Chicago reported at least three tornadoes; Fox 32 cited five; another ABC 7 segment mentioned six.
- EF Ratings: Some sources list the Mokena tornado as EF-1, others as EF-2.
- Casualty Figures: One death is confirmed, but the full extent of injuries remains unclear.
