A powerful storm swept across the Chicago area Tuesday, spawning at least three tornadoes, damaging homes and businesses and flooding roads

The storm brought powerful winds across the region and multiple tornado warnings across the region Tuesday morning, with the National Weather Service confirming two EF1 tornadoes and a third tornado in Will County near Mokena. The severe weather also produced torrential rain, powerful winds and warnings of potentially very large hail overnight. At least one person died in Northwest Indiana in a weather related house explosion as the powerful storm swept across the region.

Tornadoes and Fierce Winds Hit Suburbs

The National Weather Service said an EF1 tornado traveled from Monee to Crete, while another EF1 moved from Orland Park to Flossmoor. Damage near Mokena was also consistent with an EF1 tornado.

Residents described frightening conditions as trees were uprooted and roofs were damaged. Lansing resident Ashley Ellis said, “The wind was just going crazy,” as trees were pushed back and forth during the storm.

At Homewood-Flossmoor High School, about 250 students and faculty members took shelter as the weather intensified. Superintendent Jennifer Norrell said staff ensured everyone was moved into areas away from “glass, windows or skylights” and took the threat seriously.

The severe storm affected animals across several communities with stray animals and wildlife facing risks from falling trees, debris, flooding and damaged buildings. At the Orland Park animal hospital, the roof was damaged, but officials confirmed that all pets were safe. The storm also left trees and debris scattered across residential areas, potentially displacing stray animals and wildlife from their usual shelters. Reports from affected neighborhoods highlighted widespread property damage, but no major animal deaths were reported in the information available. As cleanup continues, animal shelters and rescue groups may also face challenges dealing with displaced or lost animals.

Power Outages, Flooding and Travel Disruptions

Flooding forced closures of viaducts in Homewood, while debris blocked roads and portions of Interstate 55. A semi also rolled over near Wilmington, adding to transportation problems.

More than 5,00,000 homes and businesses across the Chicago area lost power. ComEd said nearly 3,000 employees and contractors were working to assess damage and restore service. Air travel was also disrupted, with about 250 flights canceled at O’Hare.

More Severe Weather Possible

Officials warned that additional storms could redevelop around midnight, bringing another threat of large to very large hail. The latest severe weather comes after a summer of repeated storms across Northern Illinois.

Business Fortune urges residents to monitor weather alerts, avoid unnecessary travel and remain prepared for additional severe conditions.
