Severe storms brought rain, damaging winds and reports of tornadoes to south-central Wisconsin late Sunday.
A tornado may have touched down in Iowa County around 11 p.m., Brian Hahn with the National Weather Service in Sullivan said.
Hahn said the Weather Service received reports of a "swath of damage" from Highland east toward Dodgeville. Straight-line winds could also have been the cause. No injuries were reported.
The Iowa County Sheriff's Office said it had received reports of wind damage. A message left with the Iowa County emergency manager was not immediately returned.
The storms were part of a system that tracked northeast across parts of Kansas, Missouri and Iowa earlier in the day. Tornadoes were reported in those states, although there were no reports of injuries.
The Weather Service says the storms could continue in Wisconsin into the early morning hours Monday. Hail, damaging winds and tornadoes are possible.
A tornado watch is in effect for 11 counties in southern Wisconsin and 11 counties in northwestern and north-central Illinois until 4 a.m. Central time.
A flood advisory was also issued for parts of south-central Wisconsin due to the possibility of heavy rainfall.
