Storm, tornadic threat shifts into eastern Prairies Monday
A low-pressure system is moving into southern Manitoba, bringing a significant risk of severe thunderstorms and potential tornadoes. Residents are advised to monitor local weather alerts, especially during the evening and nighttime hours.
Why it matters
Tornadic activity poses an immediate threat to life and property, and the shift to nighttime storms increases the danger due to reduced visibility.
Forecast Centre The Weather Network Published on Aug. 24, 2026, 12:36 PM Southern Manitoba will be the main focus on Monday as conditions align for tornadic storm development.
This past weekend's storm risk may have been centred on Alberta and Saskatchewan , but the focus will shift east into Manitoba on Monday as forecasters track a low-pressure system that could trigger severe thunderstorms.
Southern Manitoba will be near the "triple point," where cold air, warm air, and an occluded front all intersect. This typically supports an environment for increased wind shear and low-level lift—the main ingredients for tornadic, severe weather.
Keep an eye out for local weather alerts and approaching storms on Monday evening and into the nighttime hours.
Behind the low's fronts, folks across southern Alberta and Saskatchewan will feel the winds pick up, with gusts of 40-60 km/h that may toss loose items.
