CALGARY -- Avalanche Canada, Parks Canada and Kananskis Country officials have issued special warnings for mountain ranges in eastern B.C. and western Alberta this weekend as warm temperatures could destabilize snow packs.  

This special warning applies to the following regions:

  • North Rockies;
  • Cariboos;
  • Jasper National Park;
  • Banff, Yoho, & Kootenay National Parks;
  • Kananaskis Country;
  • South Rockies;
  • Lizard and Flathead, and;
  • Waterton Lakes National Park.

“There are persistent weak layers in the snowpack all across this area,” said Karl Klassen, warning service manager for Avalanche Canada.

“When the sun and these high temperatures hit this complex snowpack, it’s going to have a destabilizing effect that will make natural and human-triggered avalanches much more likely.”  

Officials say several close calls have been reported recently and avalanches have been running the full length of their paths in national parks.

“There is a lot of uncertainty with these weak layers,” said Klassen. “These warm temperatures are going to be a concern across all these regions, with the most significant impact in the south.”
