Watches & Warnings

Areal Flood Watch
Issued: 9:04 PM EST Feb. 18, 2018 – National Weather Service

... Flood Watch remains in effect from Monday evening through late
Tuesday night...

The Flood Watch continues for

* much of northern Illinois and extreme Northwest Indiana.

* From Monday evening through late Tuesday night.

* Unseasonably warm and moist air will overspread the region over
the next few days with several rounds of showers and
thunderstorms expected between early Monday morning and
Wednesday. Expect area wide rainfall totals of over an inch with
many areas potentially receiving 2 to 4 inches.

* Grounds remain frozen, therefore much of the rain will result in
rapid runoff. In addition, many areas north of I-80 have snow on
the ground still and melting of this snow will compound runoff
from heavy rainfall. Ice jam break up is also a concern. Expect
rises on area rivers and streams that may result in flooding.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
