A tornado warning issued by Environment Canada about 100 kilometres southwest of Ottawa has ended, while parts of eastern Ontario and western Quebec are still under tornado watches.
The tornado warning affected parts of Central Frontenac, western Lanark county, and the Kaladar, Ont., region Thursday afternoon.
It had ended by 7:40 p.m., although the area is still included in the ongoing tornado watches.
Environment Canada issued the tornado watches at 6:20 p.m. for western Quebec and parts of eastern Ontario including Pembroke, Bancroft and Barry’s Bay.
As of 8 p.m., a severe thunderstorm watch was in effect for the region around Ottawa and South Frontenac. Conditions are favourable for severe thunderstorms that may produce a tornado this evening.
East of Petawawa and Barry’s Bay, there is still a severe thunderstorm warning in effect.
Tornado watches mean conditions are favourable for possible tornadoes, while tornado warnings mean a tornado has been reported or there’s good evidence one is imminent. The same is true of severe thunderstorm warnings and watches.
If a tornado forms, residents are advised to stay away from exterior walls and windows, ideally in a basement or on the ground floor, and to get out of vehicles.
Forecasters say the storm could also bring winds gusting over 100 km/h, heavy rain and large hail.
