Assess for wind slabs near ridge crests and in steep terrain.
Recent isolated flurries may have formed small but reactive wind slabs.
Recent, isolated flurries have formed small wind slabs. They are expected to be confined to immediate lee slopes near ridgelines and high points, they could be reactive where they have formed over surface hoar.
On Sunday, explosives were used to remove cornices. The falling cornices did not trigger slabs on the slopes below.
A few small, natural cornice falls were observed last week.
Isolated flurries have deposited 5 to 10 cm of low-density snow (larger amounts in the northern part of the region), which has been redistributed by strong winds.
This new snow overlies a crust, with surface hoar above it, on all aspects and elevations except north facing alpine terrain where it overlies wind pressed snow. The surface hoar is largest and best preserved on sheltered treeline and below treeline features.
Cornices are large and overhanging.
The mid and lower snowpack is well settled.
