If you live in Ottawa, or in areas around the national capital, be warned that Thursday will be another hot and humid day and severe thunderstorms could be on the way.

As of 3 p.m. the weather agency had upgraded severe thunderstorm watches to warnings for Ottawa, Renfrew-Pembroke-Barry’s Bay, Smiths Falls-Lanark-Sharbot Lake, and Stirling-Tweed South Frontenac.

WATCH (July 4, 2019): Heat warnings, watches issued for Ont., Que., N.B., N.S.

“A long line of thunderstorms extends from north of Peterborough to Renfrew and is moving east at 50 [kilometres an hour],” Envrionment Canada wrote.

“Strong wind gusts in excess of 100 [kilometres an hour] are possible along with hail and heavy rain. This squall line also has the potential to produce isolated brief tornadoes.”

The following areas in eastern Ontario remain under thunderstorm watches:

  • Brockville-Leeds and Grenville
  • City of Ottawa
  • Cornwall-Morrisburg
  • Prescott and Russell
  • Renfrew-Pembroke-Barry’s Bay
  • Smiths Falls-Lanark-Sharbot Lake
  • Stirling-Tweed-South Frontenac

On top of that, Ottawa, Brockville, Cornwall, and Prescott and Russell are all under heat warnings for the day, according to Environment Canada.

Thanks to “a hot and humid air mass” that has parked over those areas for the day, temperatures are expected to reach 31 C, with the humidex peaking at 39.

Environment Canada says a cold front this evening should cool temperatures down going into Friday.

Until then, the agency recommends staying in “a cool place.”

“Never leave people or pets inside a parked vehicle,” the weather agency cautioned.

Ottawa Public Health suggests drinking plenty of fluids, “preferably water,” and limiting consumption of caffeine and alcohol in the heat.
