According to the National Weather Service, the last time an active tropical system passed over Iowa was in 1900, which was left over from the hurricane that devastated southeast Texas that year. The National Weather Service is waiting for an assessment by the National Hurricane Center to confirm if the storm center passed over Iowa.

An additional round of moderate to heavy rain is possible today, with a flash flood watch continuing until the early afternoon. Windy conditions are also expected, with wind gusts up to 40 MPH possible through the evening.
