The rain and storms will be around through the overnight hours, tapering to showers after daybreak on Monday. The showers should move out of the area by mid-morning Monday, with clouds breaking for sunshine by Monday afternoon. No less, the effects of heavy rain could continue the potential for flooding into the morning on Monday, especially along some rivers and streams, as well as in low-lying and poor drainage areas.

As a reminder, if you encounter flooding on the roads, turn around, don’t drown. In other words, seek an alternate root and don’t drive through flood waters as your vehicle could stall and become stuck in the flooded conditions, and possibly float away. More so, if you reside in a flood-prone area in Central Wisconsin or by a river/stream, be aware of changeable conditions that could lead to flash flooding if heavy rainfall occurs.
