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.
10-20 cm of recent storm snow accompanied by strong SW winds will have created fresh wind slabs in alpine and tree-line regions.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Light flurries (5-10 cm) and strong SW winds forecasted for Wednesday. Day-time highs at tree-line around -1. Slight cooling trend for Thursday with mixed sun and cloud.
5-10 cm of fresh snow (and more expected on Wednesday) accompanied by moderate SW winds have created fresh windslabs in lee alpine terrain. The midpack consists of 25-35 cm of facetted snow overtop of the Nov 8 crust. The lower snowpack consists of facets and depth hoar. Snowpack depths at treeline vary from 60-90 cm with up to 140 cm in lee areas
Reports of newly formed wind slabs isolated to ridge crest have been reactive to explosive control and ski cuts. All observed avalanches were size 1-1.5.
