A tornado warning issued for Ingleside, Ont. and a thunderstorm warning issued for Ottawa have been lifted but an extreme heat warning remains in effect.
According to Environment Canada’s orange-level heat warning, temperatures are expected to have peaked on Thursday, but will remain high into Friday.
“The hottest conditions are expected to continue through today, with maximum temperatures up to 35 degrees Celsius expected. Minimum temperatures of near 21 degrees Celsius will provide little relief from the heat,” Environment Canada says.
A temperature of 32 C was recorded in Ottawa at 3 p.m. Thursday, with a humidex of 42.
The orange level on Environment Canada’s colour-coded scale refers to weather that is likely to cause significant damage, disruption or health impacts. Environment Canada is advising residents to take steps to protect themselves from the heat.
- Limit exposure to the sun and heat
- Wear lightweight and light-coloured clothes
- Close blinds and shades, and open windows if it is cooler outside than inside
- Turn on air conditioning and use fans
- Move to cooler areas of your living space
- If there are no cool areas in your living space, move to a cool public place like a pool, cooling centre, community centre or library
- Drink water before you feel thirsty to replace fluids
Tornado warning
Environment Canada issued the tornado warning for an area around Ingleside towards the St. Lawrence River in southeastern Ontario shortly before 4 p.m.
According to Environment Canada’s red-level warning, meteorologists were tracking a severe thunderstorm that could produce a tornado. They said damaging winds, large hail and intense rainfall were also possible.
“This is a very dangerous and potentially life-threatening situation,” Environment Canada said.
“Take cover immediately in a basement, interior room, or a sturdy shelter when threatening weather approaches. If no shelter is available, lie in a low spot and protect your head from flying debris. If you are out on the water when threatening weather approaches, return to shore and seek shelter, if possible. Otherwise, move away from the path of the tornado to escape. Wear your lifejacket, lie face down and protect your head.”
The warning was lifted before 4:30 p.m.
Thunderstorm warning
A yellow-level thunderstorm warning was issued for Ottawa at 3:52 p.m., with Environment Canada saying that meteorologists were tracking a storm over Manotick that could affect other areas around the city.
Locations in the thunderstorm’s path included Manotick, Osgoode, Greely, Metcalfe, Russell, Vars, Clarence-Rockland, Bourget and Casselman. The storm could produce 90 to 110 km/h winds, golf ball sized hail and heavy rain.
“Heavy rain may cause flash flooding and significant reductions to visibility. Large hail may cause significant damage and injury. There is a risk of injury,” Environment Canada wrote.
“Take immediate cover if a thunderstorm approaches. If outside, protect yourself from flying debris and hail.”
Environment Canada issues severe thunderstorm warning when there are imminent or occurring thunderstorms that could produce damaging hail, wind or rain.
The severe thunderstorm warning was lifted before 4:30 p.m.
Thunderstorm watch
The yellow-level warning was preceded by a yellow-level thunderstorm watch that was issued for Ottawa just before 11 a.m. The watch was lifted shortly after 7 p.m.
Environment Canada said conditions were favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.
“Thunderstorms may develop over the area. Strong wind gusts, large hail and heavy rain are the main threats. There is also a risk of tornadoes,” the weather advisory says.
A potential storm could bring wind gusts near 100 km/h, heavy rain possibly exceeding 40 mm, and up to ping pong ball sized hail.
Environment Canada forecasted the risk of thunderstorms between 2 p.m. and 9 p.m. Thursday.
This comes as Ottawa cleans up from a record-breaking rainfall on Canada Day that cancelled festivities, flooded streets and basements, and knocked out power to tens of thousands of people, with 118 millimetres of rain recorded at the airport.
The weather in Ottawa on Thursday is similar to what was seen on Wednesday prior to storms developing, with sweltering heat and high humidity.
Ottawa Mission reaching out to homeless residents
Extreme heat is putting homeless residents at risk.
Peter Tilley, CEO of the Ottawa Mission, told CTV Your Morning Ottawa on Thursday that frontline staff will be on the streets Thursday, keeping an eye on the most vulnerable.
“Our frontline staff are regularly doing rounds, handing out water, ensuring people are staying hydrated. Even if someone’s not staying at the Ottawa Mission, we’re inviting people in the area. You can come inside where there’s air conditioning, just get out of the heat, even for an hour,” he said, adding other volunteer groups will be doing the same.
Tilley said dehydration is a significant risk for people living on the street.
“We’re looking for risks of exposure because we’ve had a couple of hot days, but not a spell like this, where somebody’s going to be hit day after day, maybe exposed to the elements, and certainly dehydrated within an hour in weather like this.”
If you see someone who needs help, you can call 311. If you suspect they’re in danger, call 911.
Tilley also said a simple “are you okay?” can go a long way.
“I’d be careful advising someone to approach someone who’s in a volatile situation, but most people who are under the influence of drugs or have mental health issues are just struggling, and maybe just a quick word, ‘Are you okay?’” he said.
“I had to do that. I found a woman passed out in the parking lot the other day, and she soon got up and revived and moved on, but just, ‘Are you okay?’ And if not, call 911.”
