ESFLOT Favorable conditions for river ice development and possible ice jams are expected through Wednesday morning, impacting the Rock, Fox, Des Plaines, and Kankakee river basins. Bitterly cold temperatures will persist through Wednesday morning. This will make conditions favorable for the rapid formation of river ice on area rivers and tributaries. River ice spotters and river gauge data indicate that most area rivers already have some areas of heavy river ice including a few minor ice jams. New ice jams will be possible along the Rock, Fox, Des Plaines, and Kankakee rivers, including their tributaries. Any ice jam that develops will have the potential to cause rises on area rivers with little warning and isolated areas of flooding are possible. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons along area rivers should continue to monitor the latest forecasts into next week. This product may be updated by Tuesday afternoon.More
