Watch for signs that the supportive surface crust is breaking down with daytime warming. When this occurs be well away from avalanche terrain.

Summary

Weather Forecast

There will be some overnight recovery tonight offering stability to the morning snowpack.Â A mix of sun and cloud for Wednesday with daytime highs in the alpine of close to zero centigrade.Â Some light precipitation is forecast overnight on Wednesday and Thursday morning with freezing levels of close to 1900m below which expect rain.

Snowpack Summary

The snowpack is isothermal at treeline and below on all aspects (and into the alpine on solar) - the upper snowpack in these areas has undergone multiple melt-freeze cycles, a strong crust in the morning will weaken with solar input/daytime warming. On north facing alpine slopes up to 15cm of settled storm snow overlies previous old dry surfaces.

No new avalanche activity observed or reported.Share your observations with the community on the CAA Mountain Information Network

Confidence

Intensity of incoming weather systems is uncertain on Thursday

Problems

Loose Wet

Daytime heating will destabilize the snowpack as the surface crust melts. At lower elevations on solar aspects this process will happen more quickly then on Northerly facing slopes at treeline above. Rain will quickly melt these crusts.

Use extra caution on solar slopes if the snow is moist or wet.Travel early before the heat of the day.

Aspects: South, South West, West.

Elevations: Below Treeline.
