Flood Watch issued June 17 at 2:20AM CDT until June 17 at 5:00PM CDT by NWS Chicago IL

Effective: Wed June 17, 2026, 2:20 AM
Expires: Wed June 17, 2026, 10:30 AM

* 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

A Flood Watch for flash flooding means rapid-onset flooding is possible, but not yet certain, based upon the latest forecasts. Flash flooding is a dangerous situation. Persons with interests along area rivers, creeks, and other waterways should monitor the latest forecasts and 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.
