Points saillants

Pay close attention to winds.  Lots of new snow is available for transport at higher elevations so when winds increase, new slabs will build quickly.

    This layer has not produced much activity of late but still remains a concern from thinner snowpack areas.

Weather Forecast

Another system is expected to cross over the forecast region here today with up to 15cm of new snow expected over the next 48hrs.  Moderate winds are forecast to persist out of the SW at higher elevations so watch for snow transport at treeline elevations and above.

Avalanche Summary

Suprisingly little natural avalanche activity but we did observed 1 Sz 2 avalanche on the south face of Commonwealth ridge area.  The slab was 150-200cm deep and 80m wide but we were unable to tell how far it ran. 

Snowpack Summary

Not much change out there today.  An additional 10cm of new snow fell overnight with some isolated moderate westerly winds at higher elevations.  These winds are building new windslabs on lee features but so far, these slabs do not seem to extend far downslope.  Moist snow was observed on solar aspects later in the day.
