...Risk for river ice formation and ice jams will continue into next
week...

Favorable conditions for river ice development and possible ice jams
will arrive tonight into tomorrow and then continue into 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, have moved into the region. An additional
period of very cold weather is expected to arrive early next week.
The formation of heavy river ice cover means that ice jams will be
possible in isolated areas, especially along the Rock, Fox, Des
Plaines, and Kankakee rivers. 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.
