Western Manitoba hit by flooding after torrential rain dumps over 100 mm

Torrential rain and severe weather have caused flooding issues across western Manitoba

Western Manitoba is experiencing flooding following days of heavy rain that dumped more than 100 millimetres across the region, with Environment and Climate Change Canada reporting 152 millimetres in Boissevain since Monday morning.

Rainfall totals had been much lower farther east, with Winnipeg receiving 27 millimetres, but the wet weather left much of the province unsettled.

Multiple slow-moving low-pressure systems pushing north from the United States brought deep moisture from the Gulf of Mexico into the Prairies, resulting in the prolonged soaking.

That setup resulted in days of heavy rain, thunderstorms  and severe weather. Strong winds also swept through southern Manitoba, with a gust of 106 km/h recorded in Morden, just west of Winkler.

A tornado was also confirmed near Rossburn on June 29, with damage assessments underway.
