Environment Canada has ended tornado watches and warnings for eastern Ontario and western Quebec.

Several storms came through the region in the afternoon Thursday bringing severe thunderstorm and tornado watches and warnings along the way.

At times all of eastern Ontario and Western Quebec had watches or warnings.

The Ottawa airport tweeted around 4:40 p.m. that the storms going through the region may have an impact on flights.

Fewer than 300 customers were dealing with power outages that began at 4 p.m. Thursday. Power was restored to the area in River ward just before 10 p.m. A spokesperson for Hydro Ottawa said lightning caused the outages.

Watches are issued when Environment Canada determines conditions are favourable for the development of thunderstorms strong enough to include a tornado.

Tornado warnings are issued when a tornado has been reported or there's credible evidence one is imminent.

The tornado watches come less than a month after a weak tornado in the Casselman, Ont., area and a devastating derecho windstorm that knocked out power to hundreds of thousands of customers in the region and killed at least 10 people across Ontario and Quebec.
