Points saillants

Rain and warm temps have caused winter sports conditions to continue to deteriorate. Many areas of the park are snow-free again and summer sports would be possible. See this MIN for photos of conditions at Cameron Lake. Enthusiastic skiers could probably find turns high in the alpine but may want to start in approach shoes.

Avalanche Summary

No new avalanches observed. No field days and poor vis into high alpine features where snow has accumulated.

Snowpack Summary

Rain has been saturating the snowpack up to 2000 m. At high elevations up to 15cm of new snow has been transported into a new windslab. This overlies old wind slabs and basal crust in the alpine. Due to warm temps and rain there is very little snow on the ground below 1800 m.

Weather Summary

Flurries, with strong to extreme winds. Freezing levels remain high at 2000m

Sat

Light snow 4-8cm expected with light to moderate NW winds. Freezing levels fall to valley bottom.
