Outstanding Prairie May and June Events

May 2023 was a busy time for NTP with two major conferences and two weeks of intern training. So we are late getting some events from May and early June published on the blog. And all of the activity then was confined to the Prairie provinces.

So below are confirmed tornado and downburst events that are new for the NTP blog in 2023.

Note that two events - the May 11 Cayley, AB tornado and the June 4 Carberry, MB tornado - are new confirmations that are being announced by NTP for the first time here. And the confirmations are the result of an important change to way that NTP confirms landspout tornadoes. More on that in another blog post!

Event summaries and a map are provided below.

====

Event Name: Cayley, AB

Date: May 11, 2023

Start Time: 6:07 PM MDT (0007 UTC)

Final Classification: Tornado (Over Land)

Final EF-Scale Rating: EF0-Default

Estimated tornado location: 50.42N, 113.85W   

Description: Witness captured video of a landspout tornado near Cayley. As no damage was reported and satellite imagery review revealed no visible damage, the EF-Scale assessment is EF0-Default. Information available insufficient to accurately estimate track length, max. path width and tornado motion.
 

Event Name: Rowatt, SK

Date: May 27, 2023 

Start Time: 8:52 PM CST (0252 UTC)  

Final Classification: Tornado (Over Land)

Final EF-Scale Rating: EF1

EF-Scale Damage Indicator / Degree of Damage: SBO/DOD-5 

Start of damage track: 50.3553N, 104.5535W

End of damage track: 50.3604N, 104.5508W

Location of worst damage: 50.3561N, 104.5531W

Description: Witnesses in southern Regina captured video and photos of a tornado near Rowatt. No injuries were reported. Structural damage was reported at a farm property in the area and was surveyed by an NTP team on May 29, 2023. Roof damage to a large machine shed was rated EF1, with an estimated max. wind speed of 150 km/h. Results of drone imagery analysis revealed a damage track 600 m long and 200 m wide. Tornado motion was from the SSW (approx. 200 degrees). The survey team documented debris that was blown up to 2.5 km NNE of the damage site, however no other signs of damage to crops or other properties was found. Satellite imagery review did not reveal any signs of a damage path.

Event Name: Jameson, SK

Date: May 28, 2023

Time: 1:30 AM CST (0730 UTC)

Final Classification: Downburst (Microburst)

Final EF-Scale Rating: EF0

EF-Scale Damage Indicator / Degree of Damage: FR12/DOD-2

Location of worst damage: 50.4128N, 104.2829W

Description: Roof damage to a home was reported in the Jameson area after a storm passed through in the overnight hours. No injuries were reported. An NTP ground and drone survey was completed in the area on May 30, 2023, documenting the structural damage along with minor tree damage in the vicinity. Damage assessed as EF0 downburst (microburst), with an estimated max. wind speed of 125 km/h. Satellite imagery review revealed no visible damage.

Event Name: Botha, AB

Date: May 31, 2023

Start Time: 4:35 PM MDT (2235 UTC)

Final Classification: Tornado (Over Land)

Final EF-Scale Rating: EF0-Default

Start of tornado track: 52.3486N, 112.5536W 

End of tornado track: 52.3633N, 112.5361W 

Description: Witnesses captured video and photos of a tornado north of Botha (northeast of Stettler). No damage was reported. Satellite imagery review did reveal a visible path through cropland, impacting no damage indicators. Damage assessed as EF0 (default) tornado, track length of 2.33 km and max. path width of 240 m. The first half of the visible path reveals tornado motion from the S (approx. 190 degrees) before shifting directions to motion from the WSW (approx. 245 degrees) for the remainder of the path. Average tornado motion was from the SW (approx. 225 degrees).
 

Event Name: Carberry, MB

Date: June 4, 2023

Start Time: 2:53 PM CDT (1953 UTC) 

Final Classification: Tornado (Over Land)

Final EF-Scale Rating: EF0-Default

Start of tornado track: 49.8844N, 99.3714W   

End of tornado track: 44.8806N, 99.3736W

Description: Witnesses captured video of a landspout tornado near Carberry. No damage was reported. Satellite imagery review did reveal a short visible path through cropland, impacting no damage indicators. Damage assessed as EF0 (default) tornado, track length of 460 m and max. path width of 70 m. Tornado motion was from the NNE (approx. 20 degrees).

Event Name: Peerless, SK

Date: June 5, 2023

Time: 5:55 PM CST (2355 UTC)

Final Classification: Downburst

Final EF-Scale Rating: EF1

Location of worst damage: 54.3454N, 109.2504W

Description: Tree damage and structural damage to barns, bins and houses was reported in the areas of Peerless and Goodsoil after a storm passed through. No injuries have been reported at this time. An NTP ground and drone survey was completed on June 6-7, 2023. Damage assessed as EF1 downburst, with an estimated max. wind speed of 150 km/h. Satellite imagery review revealed intermittent downburst damage to trees along a swath approx. 30 km long (from Flat Valley to Mistohay Lake). Visible tree damage seen on satellite imagery and ground survey observations indicate a max path width of approx. 14 km.

Event Name: Lomond, AB
