Summary

Confidence

Fair - Due to the number of field observations

Weather Forecast

The next few days look dry and cool. Winds are moderate to strong from the north quarter (although wind direction will vary locally). Freezing level is valley floor by night and rising to around 800 m by day.

Avalanche Summary

Some cornice falls have been reported, but have not triggered slabs on slopes below. Last week, several full-depth avalanches up to size 3 were observed on all but north aspects. If the region gets substantial warming and sun again, isolated events like these could once again become active. Loose sluffs from steep sun exposed slopes are also possible.

Snowpack Summary

Keep an eye out for cornices, which may collapse. Small wind slabs can be found on some lee alpine slopes. On other slopes, variable surfaces include a skiff of recent snow, a sun crust or old rain crust, surface hoar, and/or surface facets. At the base of the snowpack, weak facets may be found.

Problems

Wind Slabs

Outflow winds have created small new wind slabs on lee and cross-loaded slopes. These can be triggered by the weight of a person. Also, keep an eye out for large unstable cornices that threaten your route.

Be cautious as you transition into wind affected terrain.>Give cornices a wide berth when travelling on or below ridges.>

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