May 29, 2011 — Severe storms carried a risk of tornadoes in southern Ontario Sunday evening.

The Windsor and Sarnia areas in Ontario were at risk of tornadoes Sunday evening, Environment Canada said, but the threat ended by 7:20 p.m.

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.

Tornado watches are issued when the conditions are right for tornadoes to form. Watches are upgraded to warnings when tornadoes are imminent or occurring.
