What the National Weather Service wrote

Several cars stranded in water which required assistance in Carmel and Fishers. Total rainfall ranged from 1.5 to 2.1 inches.

The wider storm

The final round of rain in a stretch of 4 days brought rain amounts of 2-4.5 inches of rain to central Indiana in addition to the 3-5 inches that had fallen. This led to additional widespread flash flooding and exacerbated ongoing creek and river flooding to a point that many main stem rivers ended up reaching major flood stage.
