Hydrologic Outlook

Hydrologic Outlook issued December 13 at 9:46AM CST by NWS Chicago IL

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 this weekend 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 next week.
Ice jams may cause rises on area rivers with little warning.

Warmer temperatures may return to the area by late next 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 outlook may be updated by tomorrow afternoon.
