A tornado warning is in effect for parts of southern Ontario as a storm system tracks across the province.
Environment Canada said at 5:25 p.m. ET that meteorologists were tracking a dangerous thunderstorm near London, Ont., that is likely to produce a tornado. Large hail and torrential downpours are also associated with the storm.
"Doppler radar indicates strong rotation about 20 [kilometres] north of London and it is moving eastward at 60 km/h," Environment Canada said. "This is a dangerous and potentially life-threatening situation."
Tornado warnings posted for areas between Brockville and Ottawa have subsequently been ended.
Many watches and warnings for severe thunderstorms were also posted across southern and eastern parts of the province, which has seen two days of hot, humid conditions.
People are advised take cover immediately if threatening weather approaches, Emergency Management Ontario recommends.
