the western shores of Green Bay and Lake Winnebago. Minor
lakeshore flooding is also expected on the western shores of the
bay, and the eastern side of Door County.

.DAYS TWO THROUGH SEVEN...Sunday through Saturday

Gusty west to northwest winds Sunday afternoon into Sunday evening
could send the ice shoves to the eastern shores of Green Bay and
Lake Winnebago.

Runoff from the weekend rainfall could cause some rivers to rise

the National Weather Service in Green Bay. Rainfall reports in
excess of one inch would also be appreciated.

318 PM CDT Sat Mar 28 2020


A strong early Spring storm will move from southwest Iowa into
central Wisconsin tonight, before reaching the northern tip of Lower
Michigan on Sunday. Several more rounds of rain showers are
expected, with total rainfall reaching three-quarters of an inch to
one and one-half inches. This amount of precipitation falling on
saturated grounds, will lead to runoff into area rivers and streams.

Portions of the Wolf and Oconto Rivers are already near or slightly
above minor flood stage. Portions of the Wisconsin, Menominee,
Embarrass and Peshtigo Rivers are already above bankfull and will
approach minor flood stage by early next week.

In addition to rising water levels, ponding on area roads, urban
areas and low-lying areas may also occur.

Residents who live near rivers or streams should closely monitor
water levels in the upcoming days. Be prepared to seek higher ground
if flooding becomes imminent.
