* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of Illinois, including the following areas, Hancock, Henderson, Henry IL, McDonough, Mercer, Rock Island and Warren, Iowa, including the following areas, Benton, Cedar, Clinton, Des Moines, Henry IA, Iowa, Jefferson, Johnson, Jones, Keokuk, Lee, Linn, Louisa, Muscatine, Scott, Van Buren and Washington, and northeast Missouri, including the following areas, Clark and Scotland. * WHEN...Through Sunday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Thunderstorms are expected across the watch area tonight into Sunday morning. Very high rainfall rates of 2 inches or greater in a short time are possible, which could lead to flash flooding particularly in urban areas.

With saturated soils from previous rainfall, these rainfall rates and rainfall amounts will lead to an increased risk for flash flooding.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
