Hydrologic Outlook
ESFLOT
Recent reports from river ice spotters and river gauges indicate
that some melting of ice has occurred over the last few days, but
isolated areas of heavy river ice coverage continue. Very cold
temperatures today and tonight will cause river ice to expand in
coverage. Ice jams will be possible in isolated areas along the
Rock, Fox, Des Plaines, and Kankakee rivers into early this week.
Ice jams may cause rises on area rivers with little warning.
Warmer temperatures may return to the area by late week, which
could begin a slow melt of river ice.
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 is the last scheduled update to the Outlook.

freezing temperatures.
