Flash flooding canceled the final day of the Wisconsin State Fair on Sunday as heavy rainfall in several Midwest states forced motorists to abandon their vehicles, cut power to thousands of households and closed busy roads.

Milwaukee County was under a state of emergency Sunday as several roads were blocked off and neighbors impacted by flooding tried to salvage what's left after what's being called a historic rainfall.

Rescue workers and emergency crews are responding to life-threatening flash flooding in the wake of record rainfall in Wisconsin, and more rain is in the forecast for Sunday night, officials said.
