A sudden summer storm made its presence felt in Waterloo Region on Thursday, leaving high water in its wake.

In the Stanley Park area of Kitchener, 50 mm of rainfall was recorded in the span of one hour.

Cambridge firefighters received a number of reports of flooded basements around the city.

There were reports of flooding both inside and outside Fairview Park Mall and elsewhere on Fairway Road.

Vince Gilchrist said he saw water “bubbling up out of the floor” after he went into the mall’s Sears store.

Further down Fairway, Jessica Biffis was amazed by what she saw a man and a van doing on the road.

“It was floating, and he could literally just push it,” she said.

As of 4:45 p.m., Waterloo Regional Police reported that they were responding to more than 20 reports of dangerous conditions around the region, primarily in Cambridge and south Kitchener.

The storm had been moving west-to-east across southern Ontario through the late afternoon.

A severe thunderstorm warning for Waterloo Region, Guelph and southern Wellington County was ended at 6 p.m.
