Back-to-back storms have unleashed record rainfall across parts of the Midwest and Southeast, flooding neighborhoods from Wisconsin to Tennessee, shutting highways and forcing scores of water rescues. The National Weather Service is reviewing several preliminary state and local rainfall records set since the weekend. In Chattanooga, Tennessee, more than six inches of rain fell on Tuesday, marking the city’s second-wettest day on record. Flash floods submerged homes, closed stretches of Interstate 24 and prompted dozens of rescues by Hamilton County emergency teams. Local officials said several people were killed, though they did not immediately release an exact toll, and urged residents to stay off water-logged roads while damage assessments continue. Farther north, the Milwaukee metropolitan area is still digging out after as much as 14 inches of rain—an unofficial state high—drenched the region between Saturday night and Sunday. The deluge sent the Milwaukee, Menominee, Kinnickinnic and Root rivers above previous record crests, flooded basements, collapsed walls and cut electricity to roughly 3,000 homes. The flooding forced the cancellation of the Wisconsin State Fair’s final day, disrupted high-school sports schedules and shuttered several businesses for weeks of repairs as municipal dump sites grapple with a surge in storm debris. The same weather system delivered 3 to 5 inches of rain across central Cook County, Illinois, amounts the Weather Service classifies as a once-in-50-year event. Meteorologists note that warmer air is enabling heavier downpours, with Chicago’s summertime temperatures up nearly 2 °F since 1990. Forecasters expect additional showers this week but say rainfall totals should stay below the catastrophic levels already recorded. Officials in affected states are asking residents to document damage and heed remaining flood warnings while hydrologists work to confirm the new rainfall benchmarks.
