A flash flood watch has again been issued for most of south central Iowa, as moderate risk of excessive rainfall has been issued by the National Weather Service Weather Prediction Center through Monday morning.

According to the National Weather Service, an additional one to two inches of rain is expected through Tuesday morning throughout most of Iowa, with some areas in the moderate risk area possibility receiving up to five inches. The long-term forecast shows areas in Iowa could rack up another 4-6″ of rain by the end of the week on average, with some potentially receiving more.
Countywide, since Friday, 1-2″ has been seen in most rain gauges in the county’s borders. However, 4-6″ of rain fell overnight in Jasper and Poweshiek Counties, prompting flash flood warnings. A flood warning is in place for the South Skunk River until Monday evening.
