Recent flurries have formed small but reactive wind slabs near ridge crests and in steep terrain.
Assess for wind slabs before stepping out into steep terrain.
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, which has been redistributed by moderate to strong southerly 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.
Exposed, south facing alpine slopes have been stripped back to a sun crust in many areas. Cornices are large and overhanging.
The mid and lower snowpack is well settled.
