* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Portions of eastern Iowa, northwest Illinois, and northeast Missouri. * WHEN...Through Saturday evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. * ADDITIONAL DETAILS... - Occasional rounds of scattered showers and thunderstorms are expected today through Saturday. Very high rainfall rates near 2 inches per hour are possible with the strongest storms, which could lead to flash flooding. Areas most susceptible to flooding will be urban and poor drainage locations. Total rainfall amounts will vary considerably across the outlook area due to the scattered nature of the storms. However, locations that get hit by repeated rounds of storms could receive as much as 2 to 4 inches of rainfall.

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
