Widespread flooding/rivers on the rise, after 7 and 8-inch rains along and south of the Interstate-88 corridor

Overnight torrential downpours across much of the Chicago area caused widespread flooding (rivers under Flood Warnings/Advisories are depicted in green on the headlined map). Rainfall ranged from just a quarter-to half-inch along the Illinois-Wisconsin state line to as much as 8.44-inches at Streator in LaSalle County and 8.03-inches near Channahon in Will County. Several reports of 6 and 7-inch rains along and south of the Interstate-80 corridor were recorded (see map below and list of greatest rainfall reports below).

More rain is expected to spread over our area tonight into Sunday which may lead to increased flooding as well as extending the flood duration on many rivers and streams.
