Saskatchewan saw only one tornado this year. Is it a sign of things to come?

Saskatchewan has broken a record for the lowest annual tornado count. One researcher says it could be part of a larger trend of tornadoes happening more frequently further east.

Traditional 'Tornado Alley' may be shifting east, says expert

Saskatchewan broke a record for the number of tornadoes we saw this year.

A low record, that is.

Only one tornado touched down. That was in May south of Regina. It did damage to a farm, but didn't cause any injuries.

Annual tornado records go back to 1984. There are fluctuations year to year, but no yearhasbeen as low as 2023.

It's a far cry from last year's twister tally, which was 25. The highest was 33 in 2012. The average is about 13.5.

Terri Lang, a meteorologist with Environment and Climate Change Canada, says the dryness of spring and summer contributed to the low count.

"If it's dry, the crops don't give off as much moisture," said Lang. "And [moisture is]a big contributor to the thunderstorms that we see across the Prairies in the summer."

The skies in Saskatchewan usually come alive during the summer. Severe storms and tornadoes can happen often and they can cause widespread damage but this summer has been a record breaking storm season for all the opposite reasons.CBC Saskatchewan weather specialist Ethan Williams has more.

Lang said typical weather patterns that bring rain and trigger storms also passed us by as the season progressed.

Lightning statistics which go back to2002 showed while Saskatchewan was above normal for strikes in May and June, wesaw the least strikes recorded in any July this year.

Lang says forest fire smoke may have prevented tornadoes, too.

The smoke blocks the sun's rays from heating the earth. Thatheat is needed to produce thunderstorms that can produce tornadoes.

Numerous locations in the province broke smoke records this year. From May 1 to Sept. 5, Saskatoon recorded 282 smoke hours an hour where smoke reduces visibility to below 9.7 kilometres breakingtherecord of 165 in 1981.

La Rongesurpassedthe 800-hour mark, shattering its record of 513 set in 2015 and topping smoke hours seen elsewhere on the Prairies.

Shifting 'Tornado Alley'

Although this is just one year of tornado data in Saskatchewan, it's possible lower tornado counts could be part of a larger trend.

David Sills, executive director of the Northern Tornadoes Project at Western University, says since 2017, his team has noticed more tornado, wind and downburst events happening in Ontario and Quebec than on the Prairies.

Of the 67 tornado reportsthe project recorded nationally so far2023, just 25 were on the Prairies.

In 2022, 39 were recorded on the Prairies, compared to 78 in Ontario and Quebec.

Sills says that could mean the traditional Canadian "Tornado Alley" on the Prairies may be changing.

"There are studies out there, especially in the U.S., that have found this subtle shift going on from the traditional tornado belt through the Plains into more eastern areas," said Sills. "That same kind of thing may be happening in Canada and the data we're collecting certainly seems to support that."

Although the studies haven't linked this shift to climate change, Sills says it may be a factor with more moisture than usual in Ontario and Quebec fuelling storms.

"To have very lush lawns in the middle of August out here is not what I remember growing up," he said.

Tornadoes have not only become more common in Canada, but theyre also happening in different places. CBCs Thomas Daigle hit the road with researchers trying to determine whats causing the changes.

Sills and his team will continue going through historic satellite data to find damage from tornadoes that may have gone unreported.

That will give them a better sense of how dramatic the shift in tornadoes has been.

That satellite data alsoincludes three tornado-warned storms that happened in Saskatchewan this year that could have produced tornadoes.

"You never know, we may find double the tornado count in Saskatchewanlooking at the satellite imagery," Sills said with a laugh.
