The threat for severe storms is expected to return Thursday afternoon and evening in southern Manitoba and northwestern Ontario, driven by an advancing cold front. In northern Manitoba, widespread rainfall has triggered rainfall warnings.
It is important to remain weather-aware, and stay up-to-date on all of the latest watches and warnings as conditions change.
Thursday: Heavy rain and severe storm risk
On Thursday, a large, organized low pressure system is set to develop over northern Saskatchewan and Manitoba, combining multiple areas of instability.
In northern Manitoba, widespread rainfall has prompted a rainfall warning, with between 50-70 mm possible in some areas through Friday night.
"Heavy downpours can cause flash floods and water pooling on roads," says Environment and Climate Change Canada (ECCC) in the warning. "Localized flooding in low-lying areas is possible."
Residents are urged to watch for possible washouts near rivers, creeks and culverts.
In southern Manitoba and northwestern Ontario, the cold front associated with this system brings the potential for severe thunderstorms.
Areas east of Winnipeg, Man., and near Kenora, Ont., could see storm activity through Thursday afternoon and evening.
A strong cap remains in place over the region, which may suppress some storm development.
