In sintesi

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.

Avalanche Summary

Wednesday's patrol noted no significant avalanche observations as the storm brought far less snow to the region compared to the Parkway.

Snowpack Summary

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.
