Hydrologic Outlook issued March 4 at 6:36PM CST by NWS Green Bay WI

ESFGRB

Mild temperatures through midweek may result in break up of river
ice, leading to potential for ice jam flooding. In addition,
rainfall amounts of 1 to 1.5 inches with local amounts up to 2
inches will occur from this afternoon through Wednesday, and most of
this will run off into rivers, as there is deep frost in the ground.
The combination of ice jams and heavy rain may lead to minor
flooding of rivers and streams. Flooding could also occur in
low-lying and poor drainage areas in central, northeast, and
east-central Wisconsin, as well as urban areas. Ponding may also
occur on area roads, leading to hazardous travel conditions.

Residents who live near rivers should watch for ice jams and
flooding of low-lying areas. Motorists should be alert for water
ponding on roads, especially this evening into Wednesday morning,
when the rain is expected to be heaviest.
