A special avalanche warning has been issued for western Canada.

The warning, issued on Monday, applies to all of the mountain ranges Avalanche Canada forecasts for, as well as those covered by Parks Canada and Kananaskis Country.

“Everyone in a backcountry party needs the essential rescue gear—transceiver, probe and shovel—and the knowledge to use it,” the news release stated. “Ensure your party re-groups well away from avalanche slopes, including overhead hazard such as cornices.”

Those heading to the mountains to snowshoe or explore the front country should also be aware that many popular summer trails are exposed to avalanche terrain.
