Flood Watch

* WHAT...Flash flooding caused by excessive rainfall is possible today.

* WHERE...Portions of north central and northeast Illinois, including the following counties, in north central Illinois, Boone, De Kalb, Lee, Ogle and Winnebago. In northeast Illinois, McHenry.

* WHEN...Until 5 PM CDT this afternoon.

* IMPACTS...Creeks and streams may rise out of their banks.

* ADDITIONAL DETAILS... - Showers and thunderstorms will continue 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
