Hydrologic Outlook
Hydrologic Outlook ILC007-031-037-043-063-089-093-097-099-103-111-141-197-201-230500- Hydrologic Outlook National Weather Service Chicago IL 1131 AM CDT Sat Jun 22 2024 ...Very heavy rain producing storms may lead to instances of localized flooding this evening... Showers and thunderstorms are expected to move across much of northern IL this evening. Heavy rainfall rates of up to two inches per hour will be possible with these storms as they shift east southeastward across northern Illinois through the evening. Rainfall amounts of this magnitude may cause instances of localized flash flooding, along with significant rises on area streams and rivers, some of which could reach or exceed flood stage, especially along portions of the Rock river. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons with interests along area streams and rivers should closely monitor the latest forecasts. There are currently no updates scheduled for this outlook. $$ Birk
