...Risk for river ice formation and ice jams increasing late this
week through next week...

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.
