Regions: Little Yoho.

A slow trickle of precipitation will effect the Little Yoho region over the next three days (~30cm), improving the ski quality. Watch for the development of windslabs in the alpine.

Weather Forecast

Between now and Wednesday expect up to 30cm of new snow in the Little Yoho region. Light to moderate West winds will create windslabs over this time period in lee areas in the alpine.

Snowpack Summary

Up to 20cm of low density snow in the last 48 hours. The Jan 30 melt/freeze crust can be found up to 2300m (higher on solar aspects). In isolated areas we expect the Dec. 18 surface hoar layer down approximately 50-70cm to remain, but triggering is unlikely.

Avalanche Summary

No new natural avalanche activity was observed or reported today.

Confidence

Forecast snowfall amounts are uncertain

Avalanche Problems

Wind Slabs

Light to moderate west wind over the next three days will generate windslabs in lee areas in the alpine. Size and distribution of avalanches will depend on local intensity of wind and amount of precipitation.

Aspects: North, North East, East, South East.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
