Residents urged to take shelter immediately
Emergency officials urged people in the warning area to move into basements or interior rooms on the lowest floor of sturdy buildings and remain away from windows.
Authorities warned that flying debris from tornadoes and severe thunderstorms can become extremely dangerous during rapidly changing weather conditions.
The National Weather Service also advised residents to:
Avoid open outdoor areas
Stay away from electrical equipment and plumbing
Bring pets indoors
Secure loose outdoor objects if time allows
Officials added that while vehicles may provide limited protection during hailstorms, they are not considered safe shelter if a tornado develops nearby.
Earlier tornado warning expires in Green County
A separate tornado warning previously issued for parts of Green County expired Sunday morning after the storm moved through the area.
However, forecasters continued monitoring conditions closely across southern Wisconsin as unstable weather patterns remained active through the afternoon.
