Joliet sits at the southwestern fringe of the Chicago metro, where I-55 runs through Will County past the Des Plaines and Kankakee rivers. This part of northeastern Illinois has a long tornado history — the devastating 1990 Plainfield tornado struck just northeast of Joliet — and the region's open farmland and fast-growing subdivisions lie directly in the path of spring and summer storm systems.

Much of Joliet's recent growth has been in new subdivisions built on former farmland, where young trees offer little windbreak and construction quality varies. Older neighborhoods near the rivers add flash-flood exposure to the storm mix, and winter storms and ice bring their own season of roof and power-line damage.

Buyers of newer homes should ask about wind-rated garage doors and roof attachments, since garage-door failure is a common entry point for destructive wind. A basement or interior safe spot, a reliable warning source, and a roof inspected after every major hail season are the basics that keep Joliet homeowners ahead of the region's storm risk.
