Heavy Rainfall Threat Across Ontario and Quebec
By Drooid · · How we work
Weather Forecast and Expected Rainfall
Environment Canada has identified a low-pressure system moving eastward that will bring showers and thunderstorms to eastern Ontario and southern Quebec. The agency projects rainfall totals of 40 mm to 60 mm in the most affected locations, with some areas potentially receiving up to 60 mm. In Ontario, the forecast covers the eastern part of the province, while in Quebec a nearly stationary warm front associated with the same low-pressure system is expected to produce similar amounts.
Areas Under Special Weather Statements
Ontario municipalities receiving the highest warnings include Kingston, Peterborough, Picton, Parry Sound and Haliburton. These communities are under special weather statements that highlight the risk of heavy rain and possible severe thunderstorms this afternoon. In Quebec, special weather statements and yellow rainfall warnings have been issued for the Bois-Francs and Eastern Townships regions, as well as for the Montreal, Vaudreuil-Soulanges and Montérégie areas. The Quebec warnings cover the period from Tuesday morning through late Wednesday night or early Thursday morning, with anticipated rainfall of 30 mm to 50 mm in the Bois-Francs and Eastern Townships and 40 mm to 60 mm in the Montreal-adjacent zones.
Potential Impacts and Safety Advisories
Environment Canada cautions that the projected rainfall could cause water to pool on roads and in low-lying areas, increasing the risk of hydroplaning and localized flooding. Visibility may be suddenly reduced during periods of heavy rain, and the possibility of severe thunderstorms adds a further hazard. Residents in the warned regions are advised to carry umbrellas, drive cautiously, and stay alert for updates from local authorities.
Official Response from Environment Canada
The agency emphasizes that the stormy weather is expected to clear from west to east later this afternoon or early this evening. It urges the public to monitor ongoing advisories and to follow any additional instructions issued under the special weather statements and yellow rainfall warnings.
