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.
