More rain, powerful winds continue to hit Alberta and Saskatchewan

Relief from the rain looks to finally be on the horizon for Alberta after multiple days of prolonged rainfall. The soaker that began Monday will begin easing off, while Saskatchewan will have another day of the heavy precipitation before it gets a break on Thursday. All in all, some areas could still see another 15-30 mm of rainfall before the low departs late week. In addition to the flood risk from the rain, intense wind gusts will continue to whip through on Wednesday. More on the impacts and what's still to come, below.

WEDNESDAY: HEAVY RAIN BEGINS TO WANE, LOCALIZED FLOODING STILL A THREAT

A potent low-pressure system that crossed the border on Monday will hang on with impacts on the western Prairies for another day or so before departing. Rainfall warnings are in still in place for much of southern Alberta and central Saskatchewan.

The system is bringing enormous amounts of rainfall, with locally 100+ mm not out of the question for some of the hardest areas by the time it ends.

The heaviest rain bands through Wednesday will be focused to the Alberta, Saskatchewan border, with just lingering showers forecast across southern Alberta where locally 60-70 mm of rain has been reported so far. An additional 15-30 mm of rain forecast for communities along the provincial borders.

As well, widespread, blustery north-northwesterly winds will continue through Wednesday, with gusts of 70-80+ km/h for Alberta and Saskatchewan. Some localized pockets of 90+ km/h are possible.

There were numerous reports of downed trees on Tuesday in parts of Alberta.

Soaking rain will continue to extend from western Saskatchewan to northern Manitoba through Wednesday, and then easing off to scattered showers Thursday.

There is also the risk for non-severe thunderstorms across the region on Wednesday.

Any that do form will remain below severe criteria, but conditions could be favourable for funnel clouds to develop with some of the storms in eastern Saskatchewan. Funnel clouds were reported in parts of southeastern Alberta on Tuesday.

There is still some uncertainty as to where the highest rainfall totals will end up, and some embedded thunderstorms within the system will also lead to additional rainfall totals.

As a result, residents shouldn't let their guard down when it comes to the threat of flooding.

"For more information on potential flooding impacts to your community, please refer to your municipality and the province of Alberta (rivers.alberta.ca) for the latest information and recommendations," Environment Canada and Climate Change (ECCC) states in the rainfall warning issued for Calgary. "Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts."

The City of Calgary declared a state of local emergency as a precaution on Monday afternoon.

According to local media, Mayor Jyoti Gondek says this will help emergency services should a need for evacuations come to fruition, but she doesn’t foresee that being required at the moment.

The system will send temperatures falling well below seasonal for the middle of June. After a seasonable weekend, daytime highs in Calgary will fall into the mid-teens through the middle of the week.

The active pattern continues in the long range, especially across Alberta. A few more rounds of widespread showers and thunderstorms are likely starting this weekend and continuing through the middle of next week. This will be highly beneficial for replenishing the groundwater and potentially wiping out the drought for much of the region, but also a risk for flooding.

A couple days of very hot weather will spread from west to east across the southern Prairies this weekend and into early next week. High temperatures will reach the low- to mid-30s across southern Saskatchewan on Saturday, across southern Saskatchewan and southern Manitoba Sunday, then northwestern Ontario on Monday and possibly into Tuesday.
