...Risks for River Ice Formation and Isolated Ice Jams will continue
the next Few Days...
Very cold temperatures tonight will be favorable for additional ice
on rivers and tributaries. Reports from river ice spotters and river
gauges indicate that isolated areas of heavy river ice coverage have
already developed. While not likely, ice jams will be possible in
isolated areas along the Rock, Fox, Des Plaines, and Kankakee
rivers. Ice jams may cause rises on area rivers with little warning.
Despite warmer temperatures expected by this weekend, widespread
melting of river ice is not expected. As a result, most river ice
that develops this week will likely remain in place through early
next week.
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 may be updated by tomorrow afternoon.
