Possible tornado in Quebec being investigated after severe storm

A severe storm swept through the Repentigny region, northeast of Montreal, on Sunday, prompting investigations into whether a tornado may have touched down. Drivers were forced to navigate through debris as authorities assessed the damage and weather patterns. The storm, which exceeded initial forecasts, led to heightened caution from Environment Canada, which noted that while there appeared to be weak rotation, it does not necessarily indicate a tornado. Environment Canada’s weather radar showed only heavy rain during the peak of the storm, with no indication of strong winds that would warrant a special warning. However, a severe thunderstorm watch was active earlier in the day. Meteorologist Kate LeClerc explained that while they anticipated a potential storm, the severity surpassed expectations. “Only after did we see it was a severe thunderstorm,” she stated. The Northern Tornadoes Project, based in London, Ontario, is collaborating with Environment Canada to investigate the possibility of a tornado. This project, known for its work in identifying and analyzing tornado occurrences, is currently on-site assessing the storm’s characteristics. Their findings will help determine whether the storm met the criteria for a tornado, even though no formal warning was issued due to the absence of strong winds. This is not the first instance of tornado activity in Quebec this summer. On July 21, two tornadoes struck different parts of the province. One, classified as an EF1, touched down near Harrington, Quebec, northwest of Montreal, with winds ranging between 135 and 175 kilometers per hour. Another, an EF0, occurred in Saint-Donat, Quebec, with winds between 90 and 130 km/h. These incidents highlight the increasing frequency of severe weather events in the region. LeClerc attributed the recent storm activity to fluctuating temperatures, noting that hot and humid conditions create favorable environments for severe thunderstorms. She emphasized that these conditions are likely to persist, contributing to ongoing weather instability. As a result, several areas in Quebec’s southern and eastern regions, including the Quebec City area, are under yellow alert rainfall warnings and severe thunderstorm watches. These alerts warn of varying levels of rainfall, with some regions anticipating between 40 to 80 millimeters of rain, and others expecting up to 100 millimeters. Communities such as Fermont and Saint Felicien-Roberval are particularly at risk. Meanwhile, areas under severe thunderstorm watches are advised that such storms can bring heavy rain, strong wind gusts, hail, and the potential for tornadoes. Authorities continue monitoring the situation, urging residents to remain vigilant and prepared for changing weather conditions. The investigation into the Sunday storm will provide further insight into the likelihood of tornado formation in the region, adding to the growing body of data on extreme weather patterns in Quebec.
