1. Introduction
On July 9, 2025, Chicago was slammed by torrential rain, leading to severe street and viaduct flooding across the city. Major intersections turned into mini rivers, public transit faced widespread delays, and emergency services were deployed to manage traffic and assist stranded drivers.
2. Timeline of the Torrential Rain
The torrential rain began late Monday night and intensified during the early morning hours of Tuesday. By 6 a.m., some areas had received over 3 inches of rain in just a few hours, overwhelming the city’s drainage systems. Weather alerts were issued by the National Weather Service, warning of flash flooding in Cook County and surrounding suburbs.
3. Areas Most Affected by torrential rain Flooding
Several neighborhoods and key infrastructure points were hit hardest, including:
- Lower Wacker Drive: Impassable in several stretches due to water pooling
- Lake Shore Drive Viaducts: Especially underpasses at Fullerton and Belmont were completely submerged
- South Side: Streets in Englewood and South Shore reported vehicle stalls and property damage
- O’Hare and Midway Airports: While flights continued, airport access roads experienced delays due to flooding
Videos and photos circulated online showed cars submerged up to their windows and pedestrians wading through knee-deep water.
4. Impact on Transportation and Commuting
Chicago’s morning commute turned into a nightmare.
- CTA buses faced major reroutes due to blocked roads
- Red Line and Blue Line service delays left hundreds waiting on platforms
- Metra lines experienced delays of up to 90 minutes on some routes

Many downtown workers opted to stay home as the city advised non-essential travel to be postponed.

The Chicago Department of Water Management and OEMC (Office of Emergency Management and Communications) deployed crews overnight to clear clogged drains and monitor rising water levels.
By late morning, city officials had:

- Opened temporary shelter stations for displaced residents and stranded commuters
Officials urged residents to report flooding via the city’s 311 system and to avoid driving through standing water.

Residents expressed frustration and concern. Some described the event as reminiscent of past historic floods, with multiple homes in lower-lying areas reporting basement flooding torrential rain
