MADISON, Wis. (AP) -- The storm system that hit northern and central Wisconsin Sunday produced a record number of tornadoes for one day in April.
The National Weather Service reports Friday there were 12 tornadoes, surpassing the record of 10 for one day set in April 1984.
The strongest tornado was an EF3 with a maximum wind speed of 140 miles per hour and that hit Lincoln County near Gleason.
Eight tornadoes were of the second weakest category, EF1, with a maximum wind speed of 110 mph. Three others were an EF2 tornado with a maximum wind speed of 135 mph.
These are the first strong tornadoes in 17 years for April in Wisconsin.
The weather service is continuing to assess damage and that means more tornadoes may be found.
