ESFLOT

Favorable conditions for river ice development and possible ice jams
will exist through today and then return early next week, impacting
the Rock, Fox, Des Plaines, and Kankakee river basins.

Very cold temperatures, favorable for rapid formation of river ice
on most areas rivers, will continue through today. After a brief
warm-up on Saturday, an additional period of very cold weather is
expected to arrive early next week. Area river gauges indicate
likely ice effects and a few minor ice jams, although no flooding
appears imminent at this time. New and worsening river ice cover
remains possible into tomorrow, which may lead to rises on area
rivers with little warning. A multi-day period of very cold
temperatures next week will likely bring another period of favorable
conditions for heavy river ice and ice jams.

No additional updates to this product are scheduled at this time,
but may be required prior to early next week if temperature
forecasts continue to indicate favorable river ice conditions.
