Storms bring flash flooding in northern Wisconsin

Some areas of northwestern Wisconsin saw between 5 and 7 inches of rain after storms rolled through Tuesday, flooding several roads.

Meanwhile, in southcentral Wisconsin, officials with the National Weather Service said a tornado was spotted just before 1:15 p.m. near Sauk City, moving northeast at about 30 mph.

People in that area, which includes Prairie du Sac, Mazomanie, and Marxville, were urged to take cover. A tornado warning was in effect during early Wednesday afternoon for parts of Columbia, Dane and Sauk counties. A tornado warning means that a tornado has been spotted on weather radar.

A larger swath of central Wisconsin was under a tornado watch until 6 p.m. Wednesday. A tornado watch is less serious than a tornado warning and indicates that weather conditions are occurring that could lead to a severe tornado or storm.

In northern Wisconsin, the National Weather Service Office in Duluth said eastern Douglas and southwestern Bayfield counties saw the heaviest rainfall Tuesday, according to meteorologist Cory Rothstein.

“We were seeing rainfall rates in excess of 2 inches an hour in spots,” Rothstein said.

The town of Gordon reported 5.2 inches of rain, and about 6.5 inches fell about 12 miles northwest of Cable. The storms prompted localized flooding in Superior, as well as water over county roads in Burnett and Washburn counties. Water also covered campsites in the Washburn area of Bayfield County.

Rothstein said Wednesday morning that reports were still filtering in.

“Just occasional road washouts here and there,” he said. “We haven’t heard of anything more significant yet.”

The storms also brought tree damage and high winds with a gust of 52 miles per hour recorded just west of Ashland. Downed trees were reported in the Spooner area and near the border of Washburn and Sawyer counties where a tree caught fire after falling on a power line.

Xcel Energy’s website shows about 200 customers were without power Wednesday morning, primarily in Vilas County.

Another round of storms raised the possibility of flooding and damaging winds Wednesday afternoon into the night.

Up to a half-inch of rain is expected in northern Wisconsin on Wednesday. In central and northeastern Wisconsin, the National Weather Service has issued a flood watch for the afternoon and evening.

About 2 to 3 inches of rain is expected, but amounts could be higher in some local areas. The region could see flash flooding of rivers, streams and low-lying areas.

Severe thunderstorms might also cause heavy rainfall and damaging winds in southeastern Wisconsin, prompting the cancellation of the Milwaukee Night Market. The market gathering, which draws up to 100,000 people on four nights each summer, has been rescheduled to Oct. 1.
