Multiple landspout tornadoes occurred Monday in central Alberta

Pimiskern says the landspout tornadoes have also not yet been given a rating.

“Landspout tornadoes are also known as non-supercell tornadoes, meaning they typically occur along a boundary; that could be winds converging into a line, and they typically occur beneath rapidly growing cumulus clouds,” Pimiskern explains.

“Whereas, supercell tornadoes, or what people typically associate with tornadoes, are associated with thunderstorms that have rotating updrafts.

Pimiskern says preliminary investigation, which included reviewing the radar, determined there was no lightning at the time these landspouts were occurring, effectively confirming they were in fact tornadoes of the landspout variety.

Landspout tornadoes are more typical for April, May and into June, with supercell tornadoes more often occurring in late June, July and August, she adds.

And because landspout tornadoes come with less noticeability as far as radar is concenred, that’s why there weren’t watches or warnings, says Pimiskern.

ECCC may issue an update later in the week, but they also encourage folks to watch for updates via the Northern Tornadoes Project (NTP) run by Western University.

You can report a tornado to the NTP here, or to ECCC by emailing abstorm@ec.gc.ca.
