Regions: Little Yoho.

Stay clear of shallow areas and trigger points. Give cornices a wide berth.

Weather Forecast

A cooling trend is expected to start tomorrow along with tapering snowfall amounts. The freezing level is expected to be around the surface. Wind is Westerly and tapering to the light/moderate range towards the end of Monday.

Snowpack Summary

Storm snow amounts to approx 15cm in the last 36 hours. Moist surface snow below 1600m and wet snow below 1300m on Friday. Expect to find small wind slabs forming in lee areas in the alpine. Generally, the snowpack is well consolidated with few weaknesses.

Avalanche Summary

No avalanches observed or reported in Yoho today.

Confidence

Due to the number of field observations on Sunday

Avalanche Problems

Wind Slabs

West winds have formed small wind slabs in predictable areas on the leeward sides of ridges. Pay close attention to how the snow surface feels, ski test on small rolls, and look for clues like cracking.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

The persistent weak layers from January and February are bonding well and have a low likelihood of triggering in most of the forecast area. The snowpack overall is quite strong, but check for yourself and look for surface hoar in the upper meter.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 2 - 3

Cornices

Large cornice failure was observed Mar 4 on Mt. Ogden. Recent swing in temperature is making large cornices highly suspect.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3
