Des Moines, Iowa – A multi day heavy rain threat is underway, with southern Iowa bracing for rainfall totals between one and three inches today and tonight. Locally higher amounts remain possible, which may lead to significant ponding on roads and an increased risk of flash flooding, particularly for locations along and south of I 80.
According to the National Weather Service, the active weather pattern will continue through the remainder of the week, with repeated rounds of rain likely causing river and stream levels to rise.

The threat for flash flooding is highest today through Friday as successive storms move through the region. Commuters should avoid flooded intersections and monitor local transit routes for potential delays caused by high water levels.
While the heavy rainfall is expected to trend southward into tonight, the pattern will lift back toward the north by Wednesday. Repeated rainfall in the same areas increases the susceptibility of small streams and rivers to overflow their banks.
Remain prepared for changing conditions as the heavy rain risk remains active through the end of the week. Watch for official flood warnings or advisories for your immediate area.
