Heavy storms could cause tornadoes Sunday afternoon in parts of southern Manitoba, according to Environment Canada.
Storms could also bring wolf-sized hail, rain of more than 75 millimeters and gusts of wind above 100 km / h, the weather agency said in an alert.
The weather is caused by a humid, unstable mass of air moving south of Manitoba from the United States, which will lead to several storms, according to the alert.
Some of these storms can be severe, with all possible severe weather, including tornadoes. Thunderstorms are expected outside the region on Sunday evening.
Tornado surveillance is in place for the following communities, Environment Canada says on its website:
- Cartwright-Roblin township, including Mather.
- Killarney-Turtle Mountain Township.
- The town of Lorne, including Notre Dame and Swan Lake.
- Louise Township, including Pilot Mound and Crystal City.
- The municipality of Pembina, including Manitou, La Rivière and Snowflake.
- The rural town of Argyle, including Baldur, Glenora and Greenway.
- The rural town of Prairie Lakes, including Margaret, Ninette and Belmont.
- The municipality of Rhineland, including Altona, Plum Coulee and Gretna.
- The rural municipality of Montcalm, including Sant Joan Baptista.
- The rural town of Morris, including Rosenort and Aubigny.
- The rural town of Roland, including Jordan and Myrtle.
- The rural town of Stanley, including Winkler and Morden.
- The rural town of Thompson, including Miami, Rosebank and Deerwood.
Environment Canada urged people in these regions to be prepared for severe weather and to protect themselves immediately in the face of threatening weather.
What to do
In the event of a tornado, or if the tornado clock is updated to a tornado warning, the weather agency recommends that people go inside to a room on the lower floor and away from the exterior walls and windows. , such as a basement, a bathroom, a staircase or an interior closet.
In this situation, people should also leave their mobile homes, vehicles, tents, trailers and other temporary or independent shelters, and move to a strong building if they can.
As a last resort, lie down and protect your head from flying debris, says Environment Canada.
Tornado clocks are emitted when weather conditions are favorable for the development of storms that could produce tornadoes, according to the alert.
There is also severe storm monitoring in other parts of southern Manitoba in the area around Melita, Boissevain and Turtle Mountain Provincial Park. Heavy hail, heavy rain and strong gusts of wind could also occur in these regions, according to Environment Canada.
Floods on the ground, wind warnings
A ground flood warning has also been issued in the southeast corner of Manitoba, the province said in a flood bulletin on Sunday.
The update comes as the province monitors a weather system that could cause 40 to 60 millimeters of rain over the next three days, with the possibility of severe storms bringing even more to certain areas.
Water levels in lakes, streams and drains are already high and soils are saturated with water, so rainfall forecasts in these parts of the province could cause landslides on Monday and Tuesday, according to the bulletin.
Depending on the intensity of the rain, the water level could rise rapidly and threaten low or nearby properties, as well as roads, intersections and other infrastructure.

With gusts of up to 80 to 100 km / h, severe wind warnings were also issued on Tuesday in the southern basins of Lake Winnipeg, Lake Manitoba, Lake Winnipegosis and Lake Dauphin.
Winds will cause water levels to rise more than five feet along the coast and cause strong waves that will add even more to the temporary rise in water levels, according to the bulletin.
People in the area should be vigilant and take the necessary precautions. Areas of Lake Winnipeg that are affected include the entire south coast of the basin south of Manigotagan on the east side to the south of Riverton on the west side of the lake.
For Lake Manitoba, the affected coastline includes areas that begin just north of Lundar Beach around the southern basin of the lake to a point near Langruth and parts of the northern basin.
The southern shores of Lake Winnipegosis and Lake Dauphin are also included as part of this wind warning.
The projected wind is also expected to reach the Whiteshell Lakes region, and water levels are expected to rise between one and two feet along the lakes.
People are advised not to travel to the Whiteshell Lakes area and the Winnipeg River Basin upstream in Ontario due to very high flows and water levels, which are expected to rise even further after it rains.
Rising water levels and rapidly changing conditions continue to pose a significant risk to public safety, according to the bulletin.
So far, 38 local states have been declared in Manitoba due to the floods.
