A flood watch will be in effect from tonight through Wednesday morning in parts of the Upper Peninsula, including Dickinson, Iron and Menominee counties, the National Weather Service said.

Excessive runoff may result in flooding of rivers, creeks, streams and other low-lying and flood-prone locations, forecasters said. Flooding might also occur in poor drainage and urban areas.

Rain is likely beginning Saturday night with a chance of thunderstorms Sunday. In the Iron Mountain area, an inch or more of rain could fall, NWS said.

Monday should be sunny, but showers are likely Monday night through Tuesday, including possible thunderstorms.
