Northerly winds and periods of convective flurries have created windslabs in the alpine.

Summary

Confidence

Good

Weather Forecast

Cold and clear on Wednesday with moderate northwest winds in the alpine. Thursday is forecast to be cloudy with a westerly flow and a chance of light precipitation.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

Variable amounts of dry facetted surface snow and pockets of surface hoar can be found above the mid-February crust. New melt-freeze crusts can be found on solar aspects at all elevations. The mid-pack is well settled. The late-Jan crust/surface hoar layer can be found about a metre below the surface in deeper snowpack areas. The mid-January surface hoar, can be found below that. These layers have gained significant strength, and chances of triggering these weaknesses have decreased dramatically. However, triggering may be possible with a large input such as cornice fall, or an avalanche stepping down, especially on slopes that see a lot of sun.

Problems

Wind Slabs

An icon showing Wind Slabs
Winds from variable directions have stripped some northerly aspects and developed new windslabs on solar aspects.
Avoid freshly wind loaded features.>Avoid travelling in areas that have been reverse loaded by winds.>

Aspects: North, North East, East, South East.
