Excited to announce that my method for estimating wind speeds based on lofted debris in tornadoes was used as contextual evidence for upgrading the Enderlin, ND tornado to an EF5!

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

“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.

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).

**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

A field of canola flattened by the recent hail storm, with ground between destroyed plants still covered in hailstones.

**Survey Announcement: Yesterday (July 9), NHP Field Ops intercepted a damaging thunderstorm near the communities of Acme & Carbon, AB. A damage survey of the combined impacts of wind & hail in the area will be conducted later today. Let us know if you have any information on this storm! #abstorm

These platforms, Super Mobile Hail Observatories (SuMHOs), will be deployed by members of the NHP field team across the US plains during the #ICECHIP field campaign. ICECHIP endeavours to improve radar-based #hail detection, hail models and forecasting, and hail warnings. @nsficechip.bsky.social

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 CSSL held an international symposium as part of the its launch in late October, 2024.

The Canadian Severe Storms Laboratory has launched 🚀. Backed by 60 years of expertise in #wind engineering—and a $20M gift from ImpactWX—it will revolutionize how we understand Canada’s most extreme #weather. At our new website, cssl.ca, you can watch a recording of the first CSSL Symposium.
