Regions: Glacier.

Watch out on solar aspects if prolonged sun occurs. Breakable crusts on many aspects up into the alpine with not enough new snow required for a refresh. Cold dry snow may be found on high elevation northerly aspects.

Weather Forecast

Cloudy with sunny periods and an alpine high of -4C with light ridge winds.Â

Snowpack Summary

7cm of snow now buries a melt freeze crust on solar aspects into the alpine and surface hoar in protected areas. Cold dry snow may be found on high northerly aspects. The seasons snow is well settled. Surface layers may slough with daytime warming.

Avalanche Summary

Cloudy skies and cooler temperatures yesterday limited natural avalanche activity. Numerous loose wet avalanches occurred with the sun on Wednesday on steep solar aspects to sz 2.5 due to the warm temps, periods of sun and a high freezing level. If the sun comes out today expect surface layer to become active.

Confidence

Timing or intensity of solar radiation is uncertain

Avalanche Problems

Loose Wet

Lower elevation temperatures have stayed around zero for the past 24hrs and the freezing level should be up to 1700m later today. Forecast sunny periods could quickly weaken surface layers resulting in surface sloughing this afternoon.

Use extra caution on slopes if the snow is moist or wet.If triggered loose wet sloughs may step down to deeper layers resulting in larger avalanches.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2.5
