Many people in southern Saskatchewan are picking up the pieces after strong thunderstorms left a trail of damage.

The storms came after a tornado warning issued for parts of south central Saskatchewan — including areas around Moose Jaw, Pense, Belle Plaine, Stony Beach, Rouleau and Briercrest — at 5:40 p.m. CST on Tuesday, according to Terri Lang, a metrologist with Environment and Climate Change Canada (ECCC).

"It kept rolling along as what we call a supercell, which is the kind of storm that can keep going for hours and hours because all the ingredients are there to keep it going," she said.

Lang said there weren't any confirmed tornado touchdowns, but updated numbers from ECCC show wind gusts in Regina reached 93 km/h and hail that ranged from a pea to a golf ball in size.

Northwest Regina was hit especially hard according to Lang, as almost 30 mm of rain fell within about an hour in that area.

Kurtis Doney, director of water, waste and environment for the City of Regina, confirmed that part of the city was hit the hardest, saying there was also some localized flooding due to storm drains being clogged by leaves, but crews were able to prevent widespread flooding.

Doney said the city received about 95 calls for service for "a wide range of situations, including debris and branches and some localized flooding."



Doney didn't have details regarding significant property damage since that would be an insurance matter, but he said, "The storm was significant in regards to wind and hail, so I do expect that there is property damage — particularly in the northwest part of Regina."

Meanwhile, many people took to social media to share what they were seeing on Tuesday.

Doney said the city will continue to remove downed trees, prioritizing ones that could be a safety risk to residents.

He also commended residents for keeping their storm drains as clear as they could, but reminded them to keep an eye out for clogged drains.

Lang said the weather system has moved east for the most part, but that parts of central Saskatchewan could see some showers on Wednesday.
