GREEN BAY, Wis. - The National Weather Service says strong storms in northeastern Wisconsin produced high winds and heavy rains and forced some PGA golf fans to take cover.
The weather service issued several tornado warnings and sirens sounded repeatedly around 4 p.m. Wednesday in Green Bay. Reports of downed trees and power lines were common across the area.
Fans at practice rounds for the U.S Open golf tournament at Erin Hills were urged to take shelter or return to their vehicles.
More than 24,000 Wisconsin Public Service customers were without power, including more than 5,000 in Green Bay. The storm also knocked out power to about 7,400 buildings in Oshkosh, 4,400 in Waupaca and 3,600 in Stevens Point.
Alliant Energy reported that about 12,500 customers were without electricity.
