...Threat for River Ice Jams Continues Next Few Days...

Very cold temperatures will continue today through Thursday,
bringing favorable conditions for rapid river ice formation and ice
jams. Many rivers in northern Illinois have already seen increases
in ice concentration and a few minor ice jams.

Although confidence in the exact timing and location of potential
ice jams is low, temperatures and river levels will be consistent
with past periods of time when ice jams have occurred. The highest
threat of ice jams is on the Rock, Fox, and Kankakee rivers.

This outlook means that elevated water levels and potential impacts
are possible, but not yet certain. Persons along area rivers should
closely monitor forecasts including the possibility of flood
watches, warnings, and advisories.

An update to this outlook is expected to be issued tomorrow.
