BULLETIN - IMMEDIATE BROADCAST REQUESTED
Flood Warning
National Weather Service Grand Rapids MI
949 PM EST Sun Feb 18 2018

...The National Weather Service in Grand Rapids has issued a flood
warning for the following rivers in Southwest Lower Michigan...

  Grand River At Jackson affecting Jackson County
  Grand River At Lansing affecting Ingham County
  Grand River At Ionia affecting Ionia County
  Grand River At Lowell affecting Kent County
  Grand River At Ada affecting Kent County
  Grand River At Grand Rapids affecting Kent County
  Thornapple River Above Hastings affecting Barry County
  Thornapple River Near Caledonia affecting Kent County
  Rogue River Below Rockford affecting Kent County

...Forecast Flooding Changed from Minor to Moderate Severity for the
following rivers in Southwest Lower Michigan...

  Looking Glass River Near Eagle affecting Clinton County

.Widespread rainfall is expected Monday morning through Wednesday
morning. Rain amounts between 1 and 3 inches are expected across all
of Southern Michigan, with locally higher amounts possible. Snow
melt will also continue. This will cause rises on rivers, creeks, and
streams, and allow water to spill into low-lying areas along rivers.

In addition, rainfall and warmer temperatures will increase the
likelihood for river ice to break up and travel down stream. Large
pieces of ice floating in the river may later pile up as they travel
downstream, particularly near bends in rivers. This could create ice
jams and increase the threat for flooding immediately upstream.

The following forecasts are based on observed and forecast 48 hour
precipitation.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Safety message... Even 6 inches of fast-moving flood water can knock
you off your feet... and a depth of 2 feet will float your car.
Never try to walk... swim... or drive through such swift water.  If
you come upon flood waters... stop... turn around and go another way.

This warning will be in effect until the river falls below its flood
stage.

Stay tuned to further developments by listening to your local
radio... television... or NOAA Weather Radio station for further
information.
