Wisconsin Public Service says the storms knocked out electricity to more than 16,000 customers. As of 9:30 a.m. 13,000 customers remained without power.
A line of severe weather tore through Florence, Forest, Langlade, Lincoln, Marathon, Marinette, Menominee, Oconto, Oneida, and Shawano Counties.
Most of the damage is from hail and smaller trees knocked down by the wind.
