A crew of scientists is heading to the Fergus space in the present day, after experiences of a attainable twister landing within the space in a single day.
“Potentially tornadic damage was reported in the Fergus area last night,” stated David Sills, government director with the Northern Tornadoes Challenge (NTP) at Western College. “An NTP team is on the way to investigate and we should be able to confirm whether a tornado did indeed occur within the next 24 hours or so.”
On X, Sills shared earlier that the radar confirmed a “wrapped up bow segment, some fairly tight rotation, and what appears to be a radar-based tornado debris signature with temporal continuity.”
Might have simply had a weak twister undergo the #Fergus, ON space. Wrapped up bow section, some pretty tight rotation, and what seems to be a radar-based twister particles signature with temporal continuity (10:17 and 10:22 CASKR scans, circled).

Whereas that investigation takes place, some residents are sharing photographs of the residual harm on social media.
“Six mature spruce trees downed or snapped off,” Scott Moore shared on X. “Bench of front porch flipped over and smashed. Siding damage on the house too.”
Scott Moore famous six mature bushes on his property had been torn down throughout a storm simply south of Fergus Nov. 10. Scientists are investigating to see if the storm qualifies as a twister.

And Kirk MacDonald additionally shared photographs of some wind harm within the space, with downed bushes.
As residents clear up the harm, some are questioning the timing of a twister alert.
In line with Prompt Climate Ontario, a twister alert was issued at 11:01 p.m. on Nov. 10.
“Well this is unusual … we have a tornado warning for this storm tracking through Caledon with Bolton in the path,” the storm watcher stated. “Yes, it’s November at 11 p.m. and we’re talking about a tornado warning.”

Properly that is uncommon… we’ve got a twister warning for this storm monitoring via Caledon with Bolton within the path.
Sure, it’s November at 11 PM and we’re speaking a couple of twister warning. 🙃

“A tornado warning was issued for the same storm but east-northeast of Fergus,” Sills stated. “I’m not sure if people in Fergus received that warning or not.”
Nonetheless, the timing of the twister alert additionally got here after excessive winds had already begun.
“We recognize the concern about the timeliness and accuracy of tornado warnings. We did a study on that,” Sills added.
Again in 2021, when a twister ripped via a small space of Barrie on July 15, there have been considerations raised the alert was issued after the twister touched down.
In that storm, the EF-2 stage twister occurred between 2:30 p.m. and a couple of:45 p.m. and the emergency alert didn’t mild up cellphones unit 2:38 p.m.
The NTP group studied 250 tornadoes in Canada from 2019 to 2021 utilizing open information, and concluded that greater than 70 per cent of tornadoes had no twister warning, together with 35 EF2 tornadoes.
“A followup assessment was conducted for the 2022 tornado season in Canada following the same established procedures,” the examine stated. “It was found that the number of both tornado watches and tornado warnings had roughly doubled, resulting in a significant increase in the probability of detection for tornado warnings.”
Nonetheless, the company gave Atmosphere and Local weather Change Canada a grade of 56 per cent for sending alerts to residents for a possible twister, and shared there was room for enchancment.
“We will be conducting another tornado warning performance assessment covering the 2023-2024 seasons that will be published in the spring,” Sills added.
