* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Portions of north central and northeast Illinois, including the following counties, Boone, De Kalb, Lee, Ogle, and McHenry. * WHEN...From 10 AM CDT this morning through this afternoon. * IMPACTS...Creeks and streams may rise out of their banks. * ADDITIONAL DETAILS... - Showers and thunderstorms are expected today. Rain may be heavy at times, with the strongest storms capable of torrential rainfall which could drop up to 2 inches of rain in just an hour's time in the hardest hit areas. Soil moisture is already quite high and stream flows elevated, so heavy rainfall could quickly result in flash flooding of streams, creeks, low lying, and flood prone areas. - http://www.weather.gov/safety/flood
