Hydrologic Statement
National Weather Service Grand Rapids MI
900 PM EST Sat Feb 17 2018

The following forecasts are for rivers in Southwest Lower Michigan...

.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. This will cause a rapid
rise of water on rivers, creeks, and streams, and allow water to spill into
low-lying areas along rivers. Flood advisories and flood warnings may
be required.

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. This forecast does not take into account rain that
will fall Tuesday through Wednesday morning.
