Hydrologic Outlook
ESFLOT
Waves of showers and thunderstorms are expected this afternoon and
evening across portions of northeastern Illinois and northwestern
Indiana. The highest rainfall rates are expected this evening as
atmospheric moisture increases to near record levels for January and
a line of showers and thunderstorms moves through the area. Small
isolated corridors may receive rainfall in excess of 1-2 inches,
especially in areas where storms orient in a more southwest to
northeast direction. Rainfall amounts of this magnitude sometimes
cause localized flooding of streams and poor drainage areas during
the winter months. Areas with streets, drainage ditches, and
stormwater drains impacted by late fall and early winter vegetation
debris may be especially susceptible to flooding.
This outlook means that elevated water levels and potential impacts
are possible, but not yet certain, based upon the latest forecasts.
Persons with interests along area streams and rivers should closely
monitor the latest forecasts. In addition, ensure that nearby
stormwater drains and ditches are cleared of debris.

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 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.
