Five more tornadoes and three downbursts in SK on June 23
NTP investigation has determined that five weak tornadoes occurred in south-central Saskatchewan on the evening of June 23, in addition to the two tornadoes that were already confirmed that day. The new tornadoes occurred at Vonda (2), Buffer Lake and Annaheim (2). Confirmations in Vonda and Buffer Lake were based on eyewitness and visual evidence, and with no damage reported were assigned EF0-Default ratings. Thanks to Braydon Morisseau for the information provided related to the tornadoes he captured.
An NTP storm survey at Annaheim following reported damage was able to provide evidence for two tornadoes there, one rated EF1 and the other EF0.
The NTP storm survey team was also able to locate tree damage associated with the previously confirmed Fulda tornado. This allowed the EF-scale rating to be upgraded from EF0-Default to EF0, and track information to be recorded.
A tree damage report was also received by NTP that allowed us to rate the Borden tornado as EF0, though there is not enough information to document a track.
In addition, the NTP storm survey team was able to gather evidence for three downbursts from this day, at Gravelbourg, Estevan and Carrot River.
Full details are provided in the event summaries below, along with maps and photos. The events can also be plotted on a map using the NTP Dashboard here.

Damage to a roof with the EF0 downburst in Gravelbourg, SK.
Significant roof damage with some wall damage with the downburst at Estevan, SK. It is likely that the large open door in the wall led to the pressurization of the structure and the loss of most of the roof, leading to an EF0 rating here.
Survey map for the Carrot River, SK EF1 downburst.
Section of warehouse roof and wall removed with downburst at Carrot River, SK. Again, it is assume that an bay door open to the wind (or early door failure) led to the damage here, but the damage here and in other locations was still enough to warrant an EF1 rating.
