In response to COVID-19 and the temporary suspension of many of Parks Canada’s visitor services, public avalanche bulletins will no longer be issued for the remainder of the 2020 spring season. This is a time to avoid the backcountry. Please stay home to help limit the spread of COVID-19, and to minimize demands placed on emergency response teams and the health care system.
The avalanche danger is variable and can range from Low to High. Travelling early in the day is recommended, as conditions can change rapidly in short periods of time due to daytime warming. Pay careful attention to the integrity of surface crusts formed overnight and rising air temperatures during the day. Dry slab avalanche danger may also exist during spring snow storms.
With rising temperatures forecast over the coming weeks, expect to see an increase in loose wet activity, especially during the heat of the day or periods of rain.
Deep layers are still responsive to large triggers (think cornices or rain) on high north faces. Though triggering this layer is unlikely, it's not impossible as evidenced by sporadic large avalanches.
Deep persistent slabs are best managed by:
Cornices are best managed by:

In most areas we are seeing a typical spring snowpack (a thick crust that is breaking down during the day over moist snow). The exception is high North facing terrain where weak layers deep on the snowpack have been triggered by cornice fall. See the Avalanche Canada Spring Conditions Guide for detailed information on typical spring scenarios.
Increasing temperatures in the next weeks will lead to increased avalanche activity where and cornice failures where snow remains; especially during the hottest parts of the day, or during periods of rain.
