Weather AlertHot Weather Turning to Rainfall in Thunder Bay

THUNDER BAY – Has it been too hot for you? It sounds like cooler and wetter weather will be here. Environment Canada has a RAINFALL Warning in effect for the city. The thunderstorms over Northern Minnesota this morning have reached Northwestern Ontario this afternoon and become a broad area of showers. The showers will be heavy at times with some embedded thunderstorms. The main threat with this weather system is the rainfall amounts which could reach 50 to 70 mm over several hours.

The speed of the rain means that there could be the possibility of localized flooding, or water going into basements.

This area of showers will move to the east, reaching Thunder Bay late this afternoon, and will continue over regions along the north shore of Lake Superior this evening and overnight.

There is still a chance that some of the embedded thunderstorms may reach severe limits with hail up to 2 cm and wind gusts up to 90 km/h. Environment Canada continues to monitor this situation and will issue additional warnings as necessary.
