 Further north in the Midwestern United States , impact was generally minor . Chantal and its remnants dropped mostly light rainfall in the states of Oklahoma , Missouri , Kansas , Iowa , Wisconsin , Illinois , Indiana , and Michigan .

Outside Chicago , minor flooding also occurred along a few creeks and low @-@ lying areas . The rainfall rate of 2 inches ( 51 mm ) per hour in Grand Rapids , Michigan caused the release of about 40 million gallons of untreated sewage into the Grand River . Despite crossing through Ontario and New York , it is unknown if any impact occurred in those two locations . In Vermont , the remnants of Chantal dropped rainfall in excess of 6 inches ( 150 mm ) along the Caledonia , Orange , and Washington county lines .
