Avalanche Forecast
Regions: Jasper.
Weather Forecast
Arctic air remained entrenched over the Prairies for Friday. Light winds shifting to the SW have brought a warmer, moist air mass into the bulletin region. Saturday morning is forecasted for some light flurries with total snowfall of 6cm for the day. Freezing level rising to 2300m and seasonally warm temps; alpine temp 1c.
Snowpack Summary
Recent snow has been blown in to an isolated wind slab up to 30cm thick. This has added to the previous slab sitting on a sun-crust on solar aspects and facets on polar aspects - these are now buried as deep as 60cm. Underneath the variable slab in the upper snowpack, as well as in shallow areas, the snowpack is generally facetted and weak.
