Aug. 10 (UPI) — 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.

Officials were forced to close the Wisconsin State Fair early as nearly 8 inches of rain soaked Milwaukee and surrounding areas overnight Saturday, according to the National Weather Service, a record for two-day rainfall, prompting flood alerts and a disaster declaration.

Local officials reported even more rain than the official totals reported by the NWS. Milwaukee mayor Cavalier Johnson said some parts of the city had received as much as a foot of rain.

Fair organizers canceled a concert by Lynyrd Skynyrd on Saturday night and closed the fairgrounds early as rain continued to soak the area and severe weather created dangerous conditions for fairgoers.
