In July, the Taste of Chicago closed down for a day due to heavy rain. In the suburbs, storms are flooding streets and basements. It’s a rainy year—the month of June had the third highest rainfall at Chicago O’Hare since records have been kept in 1959.
 


City sewers built to take on storms from days gone by are no match for today’s rainfall that lands mostly on parking lots, streets, and sidewalks instead of being absorbed into fields and patches of forest. What’s more, climate change predictions appear to be coming truelarger storms are hitting more frequently.

 

Basements and streets underwater are a serious concern, but when Superstorm Sandy hit the east coast two years ago, it illustrated that flooding of critical facilities, such as hospitals, can have widespread and possibly catastrophic impacts.

 
IISG’s climate specialist, Molly Woloszyn, is tackling the issue of flooding from the angle of better preparation and prediction. She is part of a project that is assessing the flooding vulnerability of critical buildings in Chicago, including utility providers, transportation facilities, and hospitals. She is looking at factors like location, elevation, and flooding history of the facility, but also the placement of critical systems, such as generators and potable water supplies. Ultimately, this will result in recommendations on how these facilities can shore up their structures and systems to reduce this risk in the face of future storms.
 


Molly and other project contributors at the Midwestern Regional Climate Center are also dipping into 25 years of data from the Cook County Precipitation Network to connect large rain events with their consequences, such as combined sewer overflows and reports of basement and viaduct flooding. The goal here is to help the National Weather Service make forecasts that are impact-based for the city of Chicago. 


Updating rain event reports for what constitutes a 5-year storm or a 100-year storm, for example, (meaning the probability of these storms happening is 1 in 5 or 1 in 100 years) is one part of the city’s plan for getting ahead of flooding concerns as detailed in the City of Chicago Green Stormwater Infrastructure Strategy. Planners and engineers use long term rainfall data to make decisions going forward, but the last report was released in 1992 with data up to the mid-80s. By all accounts, big storms are getting bigger and more frequent. More data is key for local decision makers. The Midwestern Regional Climate Center’s analysis of the Cook County data will provide new rainfall thresholds for various sized events over the course of the last 25 years.

Looking for a fun way to teach about marine debris? Check out Me and Debry, which is a whimsical, 30‑minute, audience‑participation play created for @UWiscSeaGrant. It helps students explore what marine debris is, why it matters, and how we can make a difference in the Great Lakes.The full script (English) and participation scripts (English, Spanish, and Hmong) are free to use, along with marketing materials for performances.Bring learning to life and start a conversation about litter in our waters!Check it out at the link in bio.#TeachingTuesday
Do you work or live along the Great Lakes coasts? Watch our newly released video series collection, containing several short videos that overview the range of coastal protection options in the Great Lakes, including:- Natural processes in the Great Lakes- Hard coastal protection structures and how they interact with/alter natural processes- Nature-based coastal solutions in the Great Lakes, ranging from green to gray approachesFind our two new video series at the link in bio.
Located in Washington, D.C., the Sea Grant Knauss Fellowship provides a unique educational and professional experience to graduate students who have an interest in ocean, coastal and Great Lakes resources, and in the national policy decisions affecting those resources. This is a one-year fellowship open to any student, regardless of citizenship, who is enrolled toward a degree in a graduate or professional program on the day of the deadline.Students enrolled at an Illinois or Indiana university or college should submit their applications through Illinois-Indiana Sea Grant by emailing Angela Archer at amcbride@purdue.edu. Students in surrounding states without a Sea Grant program should contact the National Sea Grant College Program at oar.sg.fellows@noaa.gov for a referral. Application deadline: June 3, 2026.To learn more about the fellowship, visit the link in bio.
