USA – Damaging Floods Hit Michigan’s Upper Peninsula

Heavy rain in the Upper Midwest of the USA caused flash flooding in parts of Michigan, Minnesota and Wisconsin between 16 and 17 June, 2018.

In Michigan, numerous roads have been washed out and dozens of sinkholes have been reported. Michigan Tech reported that the administrative building on the Houghton campus was flooded.

Local media said a father rescued his child from the debris after a basement collapsed due to the flooding.

On 17 June, Governor Rick Snyder said via Social Media that “the State Emergency Operations Center has been partially activated and we are continuing to monitor the situation in Houghton and Menominee Counties.”

Houghton County Emergency Management and Law Enforcement requested that residents should shelter in place in Houghton County and should not attempt to travel on area roadways. Several area roadways are washed out at this time.

NWS in Marquette said “Extensive flooding was reported in Houghton County the morning of June 17th, 2018. Many roads have been washed out from Lake Linden through Dollar Bay, Hancock and Houghton. Up to 7 inches (177 mm) of rain fell in the area between 11pm and 8am, with the majority of the rainfall coming in the 2am to 5am time frame.”

Also on 17 June, significant flooding caused roads to be washed out in areas around Pleasant Valley, Minnesota, and Drummond, Wisconsin.
