Flooding possible as southeast Sask. hammered by heavy rainfall

There’s the potential for flooding in some parts of southeastern Saskatchewan as heavy rainfall hammers the region.

A rainfall warning from Environment and Climate Change Canada covered the southeast corner of the province on Friday, stretching from Estevan to Moosmin, while the surrounding areas can also expect some significant precipitation.

Stephen Berg, a meteorologist with Environment Canada, said the heaviest rain has fallen in areas around Estevan as the weather system moved into the province from the northern U.S., though he noted that the rainfall seems to be quite localized.

“Places like Estevan have received about 63 millimetres of rain over the last 18 hours or so, whereas very nearby, Weyburn has only received about eight millimetres,” Berg explained.

“Estevan up towards Moosamin looks to be the corridor with the heaviest rainfall, maybe a little bit further to the north as well.”

Berg said the rain is expected to continue throughout most of the day on Friday, before tapering off in the evening or overnight.

“Looks like another 20-30 millimetres are possible for the region, so we might see totals close to 100 millimetres in some areas,” Berg said.

He said Estevan was getting as much as 15 mm of rain in an hour on Friday morning. That means localized flooding is a concern, he said, and residents may see rising water levels and standing water in fields.

“Might have some streets that have some standing water on them too, just waiting to drain out,” the meteorologist added.

Regina is expecting some rain on Friday as well, but Berg said the Queen City should only get about five to 10mm. Saskatoon, meanwhile, is also getting wet on Friday.

“Saskatoon’s had about nine millimetres over the last 18 hours,” Berg said. “Further to the southwest, Rosetown got 34 millimetres and Kindersley about 18 millimetres, so that’s quite a bit.”

After the rainstorms end, Berg said some clear weather is ahead, but he noted that temperatures have been dropping since the start of August.

“It looks like there’s a bit of a pattern change afoot,” Berg said. “It’s a bit cooler, certainly, but for the next few days at least it looks like it’ll be fairly clear in terms of precipitation once this system leaves.”
