ESFLOT Several waves of rain, and possibly a few thunderstorms, are likely starting early Wednesday morning and persisting through Thursday night. High moisture content in the atmosphere will lead to periods of torrential downpours, and the threat for 1 to 3 inches of rainfall on a widespread basis through Thursday night. Repeated rounds of rain over saturated soils may lead to areas of flooding and rises in river levels, including along the Rock, Fox, DuPage, and Illinois rivers. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons should closely monitor forecasts including the possibility of flood watches, warnings, and advisories. Additional statements or outlooks may be issued by tomorrow morning.

SAFETY and DATA MESSAGE

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location.
