Amidst hot and muggy conditions, Environment Canada has issued a severe thunderstorm watch for Winnipeg.
Environment Canada said Manitobans should watch out for adverse weather conditions and take the necessary safety precautions.
There is a severe thunderstorm warning for the Rural Municipalities of Morton, Boissevain, Turtle Mountain Provincial Park, Winchester, Deloraine, Whitewater, Minto Elgin, and Fairfax.
Environment Canada also warns that an intense thunderstorm has crossed the boundary south of Boissevain and is moving towards Boissevain, Killarney and Ninette.
Intense local downpours yielding as much as 50 mm of rain and large hail are likely from this slow-moving severe thunderstorm.
Manitobans are warned that some severe thunderstorms produce tornadoes.
Isolated thunderstorms in North Dakota are moving northward into Southern Manitoba this afternoon.
More development is expected this afternoon and evening in the unstable conditions. Isolated severe thunderstorms are likely to persist into the evening.
