Authorities confirmed three deaths so far. A 52-year-old woman died early Tuesday, February 20, after her vehicle rolled into a rain-filled ditch and was submerged along Illinois Route 45, south of Barr Road in Will County, IL. Peotone Fire Chief Willian Schreiber said there were multiple crashes at that intersection, which is a 'very low spot,' with water flowing across the road.
A 1-year-old girl was found dead in standing water in her family's Michigan backyard on February 21. State police said she reportedly wandered away from her home and entered the water.
The third casualty is a 53-year-old man whose car was swept away after he tried to drive across a flooded bridge near Stilwell, Oklahoma.
