The CSSL/NTP assisted the US National Weather Service (NWS) with their upgrading of the official rating of the June 2025 Enderlin, ND tornado from EF3 to EF5.

Announced by the NWS today, it’s the first EF5-rated tornado in the US since 2013.

“Scientists-turned-storm chasers” are tracking down Alberta hail storms to better understand how to protect against them.
Researchers from the Canadian Severe Storms Laboratory ( @cssl.ca ) at #WesternU spoke with the @theglobeandmail.com about the Northern Hail Project.
In Alberta’s ‘Hailstorm Alley,’ scientists-turned-storm-chasers look into the eye of the storm for answers
Researchers from Western University aim to use data from hard-hit areas to help Canada better understand – and protect against – dangerous and costly hail damage

**Damage Survey Announcement #abstorm: Yesterday (July 27) a major hailstorm tracked from W of Twin Butte, through Cardston, E to the Shanks Lake area. An NHP damage survey team will begin data collection tomorrow. Please forward us any information you may have on this event!
Image of map showing radar estimated extent of hailstorm swath through southern Alberta, beginning west of Twin Butte and tracking east-southeast through Cardston and areas to the south, continuing further east-southeast over and past Shanks Lake. Large areas with estimates over 50 mm max diameter, with several areas west of and over Shanks Lake with estimate maximum diameters of 75 mm.

**Seeking Hail Reports: Calgary was affected by a potentially damaging hailstorm this evening (July 13) between 7:45 & 8:15 PM MT, tracking SE from the NW corner of the city to S of Chestermere. Please send us your hail and hail damage reports, and if you can, save some samples! #abstorm #Calgary
Infographic indicating steps to collect scientifically accurate hail data: 1) take a photo of the hail with a reference object of known size; 2) Bag the hail in a plastic, sealable bag, removing as much air as possible; 3) Label the bag with critical information (date/time of collection, location of collection site).

The NHP has been busy preparing for field operations, both at home and abroad! For the #ICECHIP field campaign, the NHP and Western's UMS designed and built 4 platforms which collect and preserve hailstones, capture high-speed video of falling #hail, and measure hail fall speed with a small radar.

The Northern Hail Project is now active on Bluesky! Through our new Bluesky accounts, we hope to continue to engage with experts, citizen scientists, and other stakeholders to build on our knowledge and understanding of damaging hail across Canada.
