Environment Canada has a rainfall warning in place for a large portion of Alberta on Monday.

The southeast corner of the province, around Medicine Hat, is included.

The weather provider says heavy rain continues across parts of southern Alberta, with total rainfall amounts of 50 to 100 millimetres expected and some localized areas potentially receiving more than 100 mm.

The rain is forecast to ease beginning Tuesday evening, with areas near the Saskatchewan border potentially seeing moderate rainfall continue into Wednesday morning.

Officials warn water may pool on roads and in low-lying areas, creating hazardous travel conditions.

Motorists are being urged not to drive through flooded roadways and to watch for possible washouts near rivers, creeks and culverts.

Residents are also encouraged to monitor river conditions and road reports as the weather system moves through the region.

The flow rate and water levels on the South Saskatchewan River at Medicine Hat have both increased significantly since early Friday afternoon, according to rivers.alberta.ca.

It was sitting at 137 cubic metres per second as of 2:40 p.m. on May 29, before it started a sharp increase.

As of Monday at 3 a.m., the flow rate was up to 568 cubic metres per second, more than four times the rate it was moving on Friday.

The water level on Friday at 2:55 p.m. was at 2.34 metres; it has now increased to 3.71 metres as of Monday at 3 a.m.

The highest level in the past year for both. It’s just slightly above the 3.46 metres mark observed on July 25, 2025, when the flow rate was at 479 cubic metres per second.

On the Seven Person Creek in Medicine Hat, the flow rate and water level peaked early Monday, just after midnight. It reached 4.34 cubic metres per second and 1.16 metres before starting to diminish. Those levels jumped from a flow rate of 0.28 cubic metres per second and a water level of 0.51 metres on Saturday afternoon.

Ross Creek near Highway 41 also had a large increase in both flow rate and water level. It went from 0.04 cubic metres per second and a water level of 2.23 metres on Saturday afternoon to a peak of 0.46 cubic metres per second and a water level of 2.4 metres on late Sunday afternoon.

Rainfall in Medicine Hat began on Saturday shortly after 4 p.m. and has totalled 64.39 mm by 7 a.m. on Monday.
