New snow and winds have built wind slabs in lee and cross-loaded features.
This week's storm brought limited snow to this region. However, many areas were stripped from the storm's strong winds and lee or cross-loaded features will have new windslabs sitting on a weak base.
The threat of early season hazards is real and just below the surface.
New snow and winds have built wind slabs in lee and cross-loaded features.
Wednesday's patrol noted no significant avalanche observations as the storm brought far less snow to the region compared to the Parkway.
5-10cm of new snow redistributed by strong winds has stripped many areas and formed windslabs where deposited. This overlies a weak surface hoar and facet layer or a melt-freeze crust on south and west aspects. The snowpack is 30-40cm in depth with a weak facetted base.
A rain crust exists below 1800m.
