Hydrologic Outlook
Hydrologic Outlook issued February 11 at 2:17PM CST by NWS Chicago IL
ESFLOT Favorable conditions for river ice development and possible ice jams are expected beginning Friday and continuing into the weekend, impacting the Rock, Fox, Des Plaines, and Kishwaukee river basins. Very cold temperatures are expected Thursday and Friday, with conditions becoming favorable for rapid formation of river ice on rivers and tributaries as early Thursday night into Friday. Ice jams will be possible in isolated areas along the Rock, Fox, Des Plaines, and Kishwaukee rivers. Despite a brief warm-up Saturday, most river ice will likely remain in place through early next week when another period of very cold temperatures arrives. Ice jams may cause rises and fluctuations on area rivers with little warning. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons with interests along area rivers should closely monitor the latest forecasts. This product will be updated by tomorrow afternoon.
