Illinois · Preparedness Guide

Ready for what Illinois actually throws at you.

Tornadoes across the prairie, catastrophic Mississippi River floods, derechos, blizzards, and a New Madrid earthquake risk that most Chicagoans have never heard of.

About this guide

Built for Illinois. Not everywhere.

Illinois spans a thousand miles of climate and risk. Chicago and the northeast sit in the Lake Michigan weather shadow — lake-effect snow, brutal wind chills, and the occasional surprise tornado. Central Illinois is flat, open prairie — tornado and severe thunderstorm country with few natural windbreaks and long warning times if you're paying attention. Southern Illinois borders the Mississippi River flood plain and sits above the New Madrid Seismic Zone. The August 2020 derecho tore across Illinois with 100+ mph winds, causing widespread crop damage. The 1993 Great Flood submerged hundreds of communities along the Illinois and Mississippi rivers. Preparation looks different in Chicago, Peoria, and Cairo — enter your ZIP to see what matters where you live.

Local self-reliance starts with knowing your place.
