Hey there, time traveller!

A downburst was responsible for tearing roofs and snapping trees during a violent storm in Beausejour on July 26, according to investigators from the Northern Tornadoes Project.
After a ground and drone survey, the academic research group said the downburst, classified as EF-1 on the five-level Enhanced Fujita Scale, had an estimated maximum wind speed of 155 km/h.
The NTP recorded a track length of 6.4 kilometres and a maximum path width of 3.4 kilometres. No injuries were reported.
A downburst is a powerful downward movement of air that occurs during a storm.
Severe thunderstorms spawned at least one tornado while they brought large hail and heavy rain to parts of Manitoba that afternoon and evening.
Researchers gave a preliminary rating of EF-1 to a previously confirmed twister near Ranger Lakes, about 160 kilometres north of Winnipeg.
The survey was hindered by a lack of road access in the area just west of Lake Winnipeg. Satellite images showed tree damage, but clouds obscured the tornado’s path, which was at least two kilometres long and 190 metres wide, the NTP said in a blog post.
The group also observed downburst damage north of Beaver Creek, which is close to Ranger Lakes in the Interlake region.
It is investigating significant tree damage near the hamlet of Rennie, which is about 110 kilometres east of Winnipeg.
The NTP has recorded eight tornadoes in Manitoba this year.
The province averages about eight to 12 per year, according to Environment Canada, which is also investigating last week’s storm damage.
