* WHAT...Flooding caused by excessive rainfall continues. * WHERE...Southern Cedar County in east central Iowa... Iowa County in east central Iowa... Johnson County in east central Iowa... Muscatine County in east central Iowa... Keokuk County in southeastern Iowa... Northwestern Louisa County in southeastern Iowa... Washington County in southeastern Iowa... * WHEN...Until 200 PM CDT. * IMPACTS...Flooding of rivers, creeks, streams, and other low-lying and flood-prone locations is imminent or occurring. Streams continue to rise due to excess runoff from earlier rainfall. Low-water crossings are inundated with water and may not be passable. Expect many areas of slow moving or standing water. It will take several hours for all the water from these storms to work through local drainage systems in urban areas. * ADDITIONAL DETAILS... - At 804 AM CDT, Doppler radar and automated rain gauges indicated heavy rain of 2 to 5 inches occurred since last evening across the area. This heavy rain falling on saturated ground has resulted in flooding of low lying areas, streams, creeks, rivers and poorly drained areas. The threat for heavy rain has ended, but runoff will delay the fall of water levels and improvement in conditions. - Some locations that will experience flooding include... Iowa City, Muscatine, Washington, Tipton, Marengo, West Branch, Sigourney, Columbus Junction, Durant, Coralville, North Liberty, West Liberty, Williamsburg, Wilton, Kalona, Tiffin, Wellman, Lone Tree and University Heights. - This includes the following highways...
