Canada Day tornado that destroyed 3 homes rated EF4

Published

 on

A team of experts has classified a tornado that tore a path of destruction near Carstairs, Alta., on Canada Day an EF4.

The Northern Tornadoes Project (NTP), in collaboration with Environment and Climate Change Canada’s (ECCC) Prairie and Arctic Storm Prediction Centre, made the determination Tuesday following an analysis of the damage left behind.

“The survey teams found that there was enough evidence to rate the tornado damage at EF4, with a maximum wind speed of 275 km/h,” NTP said in a statement.

“The preliminary path length is 15.3 kilometres and maximum path width 620 metres.”

Officials say 12 homes were impacted by the storm: three were destroyed, four were left uninhabitable and five others were damaged.

WHAT IS THE EF SCALE?

According to ECC, the EF (Enhanced Fujita) Scale is a six-point scale that ranges from zero (weakest) to five (strongest). It was adopted in April 2013 as “a more modern and improved version of the original Fujita Scale or F Scale.

“Environment Canada used the F-Scale to rate wind damage, in particular tornado damage, for several decades. However, the F-Scale, developed by Prof. T. Fujita in the 1960s, was found to have significant shortcomings. There was a limited number of damage indicators with which to rate damage, and engineering studies had shown that the F-Scale wind speeds were not well correlated with actual damage,” ECCC said.

The new rating system takes into account a wider number of damage indicators, including homes, office towers and trees. It also “more accurately” records wind speeds by analyzing damage.

“The damage ratings are also backwards compatible with the original F-Scale; only the associated wind speeds have undergone major changes.”

F/EF Rating F-Scale Wind Speed
Rounded to 10 km/h
EF-Scale Wind Speed
Rounded to 5 km/h
0 60-110 90-130
1 120-170 135-175
2 180-240 180-220
3 250-320 225-265
4 330-410 270-310
5 420-510 315 or more

When looking at the Canada Day tornado, experts found one of the homes destroyed was “well-built.” That was factored into the storm’s strength, which placed it into the range of wind speeds of 275 km/h.

Other damage at the property also illustrated how powerful the tornado was, the NTP said.

“In terms of nearby corroborating damage, various farm equipment was flipped and thrown at that property. This includes a combine weighing almost 10,000 kilograms that was thrown at least 50 metre, and then rolled for another 50-100 metres after that.

“Wind tunnel studies of another combine that was hit by a previous Canadian tornado suggest a wind speed of 230 km/h for just flipping a combine.”

STRONGEST SINCE 1987 TORNADO

Experts also said the tornado was one of only three F/EF4 tornadoes in Alberta and the strongest since the F4 tornado that struck near Edmonton 35 years ago.

That storm, on July 31, 1987, killed 27 people and injured more than 300. It also destroyed 300 homes.

The Canada Day tornado thankfully did not cause as much damage or injuries. The NTP says only one person, a first responder, received a minor injury.

The organization says there have been 21 “violent” tornadoes in Canada that have been classified as F/EF4 or higher. The country’s only F5 tornado occurred in Elie, Man., in June 2007.

Suspicious deaths of two N.S. men were the result of homicide, suicide: RCMP

Published

 on

Nova Scotia RCMP say their investigation into two suspicious deaths earlier this month has concluded that one man died by homicide and the other by suicide.

The bodies of two men, aged 40 and 73, were found in a home in Windsor, N.S., on Sept. 3.

Police say the province’s medical examiner determined the 40-year-old man was killed and the 73-year-old man killed himself.

They say the two men were members of the same family.

No arrests or charges are anticipated, and the names of the deceased will not be released.

RCMP say they will not be releasing any further details out of respect for the family.

Turning the tide: Quebec premier visits Cree Nation displaced by hydro project in 70s

Published

 on

For the first time in their history, members of the Cree community of Nemaska received a visit from a sitting Quebec premier on Sunday and were able to share first-hand the story of how they were displaced by a hydroelectric project in the 1970s.

François Legault was greeted in Nemaska by men and women who arrived by canoe to re-enact the founding of their new village in the Eeyou Istchee James Bay region, in northern Quebec, 47 years ago. The community was forced in the early 1970s to move from its original location because members were told it would be flooded as part of the Nottaway-Broadback-Rupert hydro project.

The reservoir was ultimately constructed elsewhere, but by then the members of the village had already left for other places, abandoning their homes and many of their belongings in the process.

George Wapachee, co-author of the book “Going Home,” said community members were “relocated for nothing.”

“We didn’t know what the rights were, or who to turn to,” he said in an interview. “That turned us into refugees and we were forced to abandon the life we knew.”

Nemaska’s story illustrates the challenges Legault’s government faces as it looks to build new dams to meet the province’s power needs, which are anticipated to double by 2050. Legault has promised that any new projects will be developed in partnership with Indigenous people and have “social acceptability,” but experts say that’s easier said than done.

François Bouffard, an associate professor of electrical engineering at McGill University, said the earlier era of hydro projects were developed without any consideration for the Indigenous inhabitants living nearby.

“We live in a much different world now,” he said. “Any kind of hydro development, no matter where in Quebec, will require true consent and partnership from Indigenous communities.” Those groups likely want to be treated as stakeholders, he added.

Securing wider social acceptability for projects that significantly change the landscape — as hydro dams often do — is also “a big ask,” he said. The government, Bouchard added, will likely focus on boosting capacity in its existing dams, or building installations that run off river flow and don’t require flooding large swaths of land to create reservoirs.

Louis Beaumier, executive director of the Trottier Energy Institute at Polytechnique Montreal, said Legault’s visit to Nemaska represents a desire for reconciliation with Indigenous people who were traumatized by the way earlier projects were carried about.

Any new projects will need the consent of local First Nations, Beaumier said, adding that its easier to get their blessing for wind power projects compared to dams, because they’re less destructive to the environment and easier around which to structure a partnership agreement.

Beaumier added that he believes it will be nearly impossible to get the public — Indigenous or not — to agree to “the destruction of a river” for a new dam, noting that in recent decades people have come to recognize rivers as the “unique, irreplaceable riches” that they are.

Legault’s visit to northern Quebec came on Sept. 15, when the community gathers every year to remember the founding of the “New Nemaska,” on the shores of Lake Champion in the heart of the boreal forest, some 1,500 kilometres from Montreal. Nemaska Chief Clarence Jolly said the community invited Legault to a traditional feast on Sunday, and planned to present him with Wapachee’s book and tell him their stories.

The book, published in 2022 along with Susan Marshall, is filled with stories of Nemaska community members. Leaving behind sewing machines and hunting dogs, they were initially sent to two different villages, Wapachee said.

In their new homes, several of them were forced to live in “deplorable conditions,” and some were physically and verbally abused, he said. The new village of Nemaska was only built a few years later, in 1977.

“At this time, families were losing their children to prison-schools,” he said, in reference to the residential school system. “Imagine the burden of losing your community as well.”

Thomas Jolly, a former chief, said he was 15 years old when he was forced to leave his village with all his belongings in a single bag.

Meeting Legault was important “because have to recognize what happened and we have to talk about the repercussions that the relocation had on people,” he said, adding that those effects are still felt today.

Earlier Sunday, Legault was in the Cree community of Eastmain, where he participated in the official renaming of a hydro complex in honour of former premier Bernard Landry. At the event, Legault said he would follow the example of his late predecessor, who oversaw the signing of the historic “Paix des Braves” agreement between the Quebec government and the Cree in 2002.

He said there is “significant potential” in Eeyou Istchee James Bay, both in increasing the capacity of its large dams and in developing wind power projects.

“Obviously, we will do that with the Cree,” he said.
