Northern Tornadoes Project (NTP) Say an EF0 downburst hit the Mallorytown Area During the Storm on June 22nd

Mallorytown – The Northern Tornadoes Project (NTP) say an EF0 downburst or microburst hit the area during the storm that hit the Mallorytown area in the early morning of June 22nd.

A fatality and a serious injury were later reported in a campground, related to falling trees. An NTP ground and drone survey was completed on June 24, 2025, documenting the tree damage in the area.

A downburst includes microbursts, defined as downbursts with a maximum diameter of 4 km or less.

The NTP say the damage was assessed as an EF0 downburst, with an estimated max. wind speed of 115 km/h, with intermittent damage found over an area approximately 9 km long and up to 5 km wide. The start time is radar estimated. Satellite imagery review revealed weak tree damage.

The Northern Tornadoes Project (NTP), founded at Western University in 2017 with the support of social impact fund ImpactWX, aims to better detect tornado occurrence throughout Canada, improve severe and extreme weather understanding and prediction, mitigate against harm to people and property, and investigate future implications due to climate change.

Western University also partners with the University of Manitoba, Pelmorex, The Weather Network, Instant Weather and CatIQ, and closely collaborates with Environment and Climate Change Canada and several Canadian and international universities on this Project.
