A tornado watch is in effect for Ste. Anne and the surrounding area as of Monday afternoon, June 29, 2026, with Environment Canada warning of conditions favourable for severe thunderstorms that could bring large hail, heavy rain, strong winds, and even tornadoes. Residents should be prepared to take cover if the weather turns dangerous, especially later this afternoon and into the evening.
The Environment Canada watch was issued at 2:21 p.m. CDT for the R.M. of Ste. Anne including Richer, with a moderate impact level and high forecast confidence. The agency says a developing low pressure system and frontal wave are mixing with an unstable atmosphere over southern Manitoba, creating the right ingredients for severe storms.
As of 3:00 p.m., the weather station in nearby Kleefeld reported a temperature of 25.9°C with 78 percent humidity, making it feel like 35 with the Humidex. Winds were blowing from the east-northeast at 20 km/h, gusting to 29 km/h. The combination of heat, moisture, and wind is fuelling the storm risk.
Forecasters say the most active period is expected from 4:00 p.m. onward, when storms may strengthen and start to rotate. A strengthening jet stream is likely to add more energy to the developing thunderstorms through the afternoon and evening. This comes just one day after a tornado was confirmed near Rossburn, and meteorologists believe Monday’s setup could be even more favourable for severe, tornado-like storms.
The seven-day outlook for Ste. Anne shows that the storm risk will continue into Monday night, with showers or thunderstorms and a low of 16°C. Conditions will improve mid-week, with mainly sunny skies on Tuesday and a high of 24°C (Humidex 29), followed by sunny days Wednesday and Thursday with highs of 25°C and 27°C. Showers are expected Friday, with a chance of showers Saturday, highs around 26°C both days, before next Sunday becomes sunny and 28°C.
