Earlier in the evening, the weather agency issued a tornado watch for Windsor, Essex, Chatham-Kent, Sarnia and Lambton. Environment Canada also issued a brief tornado warning for Windsor, Leamington and Essex County.
During the warning, the province of Ontario issued a “red alert” urging people to immediately take shelter.
Environment Canada cautioned of “severe thunderstorms capable of producing tornadoes.”
Damaging winds over 100 km/h were forecast. Other threats included large hail and heavy rainfall -- 50 mm in the span of one hour or less.
