Cold temperatures this week have caused a significant increase in
river ice across the area, including multiple ice jams. Cold
temperatures are expected to continue into next week, with favorable
conditions for river ice formation. Areas of open river may see new
ice growth, while areas with existing ice cover my thicken.
No widespread flooding is expected, but ice jams will be possible in
isolated areas, especially along the Rock, Fox, and Kankakee rivers.
Ice jams may cause rises or fluctuations on area rivers with little
warning.
Persons with interests along area rivers should closely monitor the
latest forecasts.

Bitterly cold temperatures moving into Michigan over the next few
days will increase the risk of ice jams on rivers. While many
locations have already frozen over, ongoing ice growth will continue
to increase in any open water areas.
These temperatures have not been seen for many years in West
Michigan, which means that some areas that don't typically
experience river ice jams may have issues this year. Ice jams can
result in water levels rising much more quickly than usual, which
can catch people off guard. Anyone living or working near rivers in
West Michigan should prepare now for potential river ice and rising
water levels.
While temperatures warm up a bit early next week, this overall cold
weather pattern will continue through at least next week, which will
keep ice locked in place on the rivers.
