Kernpunkte

Some good snow can be found on sheltered northerly facing slopes near treeline. Watch for any signs of the snow melting with rain or solar radiation. At these times the danger will increase

    This condition is most prevalent in the alpine near ridges and open bowl features. Near treeline the slabs are most threatening when sitting over buried sun crust on southerly facing slopes.

    Cool temperatures are limiting the extent of this problem. This can change rapidly with solar radiation particularly near rock alcoves that act like solariums. Watch for signs of snow melting during the day. These events will likely scrub to ground.

Weather Forecast

Over the next 36hrs freezing levels are expected to remain below treeline. Snow flurries at upper elevations may produce up to 10cm with rain below. Solar radiation will be limited with mostly cloudy skies and  light to moderate variable winds from the West and North. A warming trend will resume towards the weekend.

Snowpack Summary

A crust extends to treeline (TL) on all aspect and on sunny slopes to near 2300 m. The crust will maintain its strength until it is exposed to prolonged sun and warm temperatures. Wet to moist snow is present below the crust depending on elevation and aspect. Windslabs are found at and above TL slopes near ridges into the alpine. Cornices are large

Avalanche Summary

No new avalanche observations over the past 24hrs on Tue with the cooling temperatures and overcast sky.

Confidence

Freezing levels are uncertain on Friday
