Severe thunderstorm warning lifted for Ottawa-Gatineau

Environment Canada has lifted a severe thunderstorm warning for Ottawa-Gatineau, although it continues to track powerful storms capable of brutal wind gusts and toonie-sized hail.

As of 8 p.m. ET, the only remaining thunderstorm warnings were in western Quebec, including such communities as:

  • Maniwaki
  • Gracefield
  • Wakefield
  • Chelsea
  • Quyon

A severe thunderstorm watch remains in place for Ottawa-Gatineau as well as many surrounding communities including Kingston, Pembroke, Cornwall, Perth and Brockville.

In Ottawa, storms this evening could produce wind gusts of up to 90 km/h and toonie-sized hail, Environment Canada said.

The agency had previously issued tornado warnings for the Barry’s Bay and Deep River areas but those have been lifted. 

There is currently no mention of a potential tornado for the nation’s capital.

It’s the second straight day that the region has been hit by inclement weather.

Ottawa’s main airport recorded 17.4 millimetres of rain in a few hours during Tuesday’s storm, the greatest single-day volume in six weeks.

Wednesday’s forecasted high temperature in Ottawa was 30 C, with humidity potentially making it feel as hot as 37. The capital hasn’t reached 30 C since early October.

Daily heat records are possible Wednesday in communities like Brockville, Cornwall, Kingston and Belleville.
