STEVENS POINT, Wis. (AP) — Parts of Wisconsin continue to recover from destructive weekend storms.

We Energies said nearly 21,000 remain without power this morning due to one of the most powerful storms to hit the Fox Valley in two decades. Power has been restored to more than 80,000 customers since Friday night.

About 30,500 Wisconsin Public Service customers remain without service, with 8,850 in Green Bay. Nearly 4,300 Alliant Energy customers are still out of service today.

The National Weather Service has confirmed three tornadoes Friday night, one near Jeffris in Lincoln County, another near Tripoli in Oneida County and a third near Mosinee in Marathon County. The weather service confirmed a fourth tornado Saturday morning near New London.

The same system knocked out power late Friday in parts of Iron Mountain and other areas in Dickinson County, but most areas were restored within hours.
