Avalanche Summary

No new avalanches reported.

Snowpack Summary

There is about 5 cm of light dry new snow that has buried the melt-freeze crust that developed last week. The crust has been reported to be very hard with no foot penetration on solar aspects, and variable with a 10-15 cm foot penetration on shaded North aspects. There was widespread surface hoar at and below treeline before the new snow arrived, and can be found well preserved below the thin layer of new snow. Cold alpine temperatures are facetting the near surface snow at higher elevations. Some pockets of very soft slab have developed due to wind transported new snow. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.

Avalanche Problems

Wind Slabs

Changing winds may have developed thin pockets of wind slab in the alpine. Watch for reverse loading as the winds change direction.
Avoid freshly wind loaded features.>Avoid travelling in areas that have been reverse loaded by winds.>

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2
