The cleanup begins, after heavy rain, hail and strong winds whipped through Calgary Tuesday evening, leaving some damage in their wake.
The sudden storm brought flash flooding, that swallowed up some vehicles and caused delays for transit.
In some spots, the hail was so heavy it looked like snow piled on the ground.
Calgary Emergency Management Agency deputy chief Sue Henry says the biggest issue they found was catch basins backing up because of the deluge of hail and leaves that had been ripped off of trees.
A street overrun with water and hailstones inspired David DeWolfe to grab his paddle boat and set out on an adventure:
Acting Detective Jack Russell with the Calgary police says they received a call about a roof being ripped off a residential building in the northeast, thanks to the wind.
Doris Kaufmann-Woodcock with Enmax says it was likely thousands of people who went without power for at least a little while after the storm.
She says the combination of heavy hail and strong winds knocked down some lines, so the degree of difficulty in getting the power back on varied, depending on the area of the city.
Henry says the number of calls to 911 were six times the normal volume, but told CBC News there were no reports of injuries.
In all, she said, crews responded to 440 calls for assistance.
The City is asking pedestrians, drivers and cyclists to be careful navigating deep puddles, and to be cautious of broken branches hanging overhead.
