Lo esencial

Good skiing can still be found in sheltered areas in the alpine.

    Weak mid-pack facets found in sheltered upper treeline and alpine features, loaded by recent new snow and moderate SW winds may overload this interface. Not likely to trigger naturally but sensitive to human triggering.

Weather Forecast

Sunday broken skies and no new snow, Freezing levels to rise to 2300M

Monday broken skies with no new snow, Freezing levels to 2500M

Tuesday mix of sun and cloud with no new snow, Freezing levels 2600M

Snowpack Summary

10cm-20cm recent snow (elevation dependant) covers widespread wind effect from previous N winds, overlying crusts and facets in upper snowpack. The crusts are bridging on solar aspects. Occasional whumpfing at upper TL and in the ALP. Snowpack structure is generally faceted on polar aspects and weak in shallow areas.

Avalanche Summary

No new observations from field teams today.

Confidence

Intensity of incoming weather systems is uncertain
