Regions: Glacier.

The sun may come out throughout the day heating up solar aspects and might produce loose avalanches. Remember to pay attention to the overhead cornice hazard.

Weather Forecast

Scattered to broken skies today with no precipitation forecast as a southwesterly storm approaches the interior tomorrow bringing mild temperatures and moderate amounts of rain and snow into Wednesday.

Snowpack Summary

20cm low density snow over settled snow above 1700m . Mar 3 rain crust down 10 to 20cm below 1700m. Feb 12 surface hoar down 100 to 130cm.

Avalanche Summary

No new avalanches yesterday.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday

Avalanche Problems

Wind Slabs

Sustained southerly winds overnight and 10-15cm of new snow have created wind slabs at higher elevations. Caution to the immediate lee of ridge features.
Be cautious as you transition into wind affected terrain.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Persistent Slabs

The surface hoar/crust layer from February is most likely to be triggered on solar aspects from shallow areas or from large triggers such as cornice falls resulting in large avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 4
