Up to 5cm of new snow and moderate winds are forecast along the icefields parkway Saturday night.
Keep an eye out for locally forming thin wind slabs.
New snow and winds could form isolated but reactive wind slabs over the Jan 24 facets, or on top of the recently formed hard surfaces. Watch for signs of instability in wind effected terrain.
Numerous wet loose avalanches to size 2 were observed on February 4 and 5th throughout Jasper National Park. Most occurred on solar aspects below tree line, but several were also observed in the alpine on solar aspects.
There is a melt freeze crust to mountaintop on solar aspects and to around treeline on polar aspects. A weak layer of surface hoar and facets is down ~10cm, which is most problematic in areas with wind loading.
In open areas, recent winds have redistributed the new snow into windslabs. The midpack is still supportive overlying basal facets at the bottom of the snowpack.
