Severe thunderstorms developing over parts of Manitoba this morning
Terri Gale has your Wednesday morning look at the weather. It's going to be a rainy start to Wednesday for south and central Manitoba. As of 5 a.m., Environment and Climate Change Canada (ECCC) has issued a number of severe thunderstorm watches and warnings for several Manitoba communities, including Brandon, Grand Rapids, Berens River, and Bloodvein. According to the weather agency, conditions in these areas are favourable for the development of severe thunderstorms that could lead to strong winds, large hail, and heavy rain. It notes the thunderstorms are expected to persist throughout Wednesday morning. ECCC is warning Manitobans to take cover if a thunderstorm approaches as lightning kills and injures Canadians every year. It adds that heavy rain can cause flash flooding and reduced visibility; strong winds can damage trees and buildings; and that large hail can cause damage and injury.

Calgary's wet weather has resulted in swarm of mosquitoes — but it could mean fewer wasps
This summer's soggy weather has left many Calgarians slapping away what feels like more mosquitoes than normal, but there is buzz of a possible upside — we could see a quieter start to wasp season. Mosquitoes breed in water, but those same water-soaked conditions they flourish in are essentially the opposite of what wasps need to grow their colonies. "If they get a good start in the spring with a warm spring, then there's potential for the populations to be fairly large." said Ken Fry, an entomologist with Olds College. "If we get cooler temperatures, they're slower to develop, that first generation [is] slower to develop and they get a very slow start." 2024 saw a comparatively warmer and drier summer, with some pest control technicians swarmed by higher numbers of calls to come remove wasp nests. But this year is a different story, with July for example seeing a high number of wet, rainy days and chillier temperatures. The conditions can mean a more sluggish start for the queen to lay eggs and grow generations of workers. "If that's really slow, it takes a while for the colony to build up," said Fry, who predicts an average to below-average season. Population could still ramp up Typically, the most wasp activity will be in late August and early September. Fry says while it could be a quieter August, whether it gets busier is still up to mother nature. A stretch of a couple weeks of warm weather could be enough to accelerate their life cycle and create a higher population come September. Plus, more rain means more plant growth, and richer vegetation can lead to a proliferation of smaller insects that wasps can then kill to feed to their larvae. "If it warms up, we get persistent warm temperatures, like mid-20s, with all the abundant food, the warm weather for them to develop, the generation times will shorten, they'll develop more quickly and then we'll start to see the populations build," said Fry. While wasps buzzing around can be a nuisance, Fry says they do play a vital role in the ecosystem and keeping other insects in check. "What they're doing out there is feeding on insects. So, they're taking the grubs off your trees, the caterpillars off your trees, out of your vegetable garden," said Fry. And while you might not come into contact with as many wasps, if and when you do have a run-in, Fry cautions against squashing them — or you could end up with more of them on your hands.
