Below 1000 metres it has introduced a new hazard but also greatly improved travel on rugged, crusty surfaces. At higher elevations where this crust tapers out, the new snow has added significant load to a couple of deeply buried weak layers that we haven't quite ruled out as problems. The nature of avalanche activity resulting from this storm and again on Tuesday should give some clarity on this uncertainty as we move forward.

Deeper down, around 100 to 300 cm now overlies another layer of surface hoar (and faceted snow) buried in mid-February that may still be a concern in shallower snowpack areas. Although they haven't produced recent avalanches, professionals in the region have been tracking and treating these layers with caution.
