Avalanche Forecast
Avalanche Bulletin - Little Yoho
Things will start to get touchy as the new snow arrives with strong W winds. Minimize overhead hazard and avoid steep confined terrain until things have a chance to settle. Sheltered areas at lower elevations may provide the best skiing.
Avalanche Problem 1: Wind Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Pay attention to overhead hazards like cornices which could trigger slabs.
Avalanche Problem 2: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
As the new snow increases the load over the March 15 crust on solar aspects we may start to see avalanche activity on this layer. If the facets below the crust also fail, larger propagations will be possible.
Travel and Terrain Advice
- Recent snow may be more sensitive to human triggering on solar aspects where it sits on sun crust
- Watch for signs of instability such as whumpfing, or cracking.
Avalanche Summary
No observations in the Little Yoho area, but three size 2-2.5 natural cornice triggered avalanches were observed today with crowns ranging from 20 to 120 cm deep. Two were observed on Helen Ridge and one was seen on Jimmy Junior near Mt Jimmy Simpson. Some whumphing on the buried crust from March 15 was also experienced in the Cirque Peak area.
Snowpack Summary
Moderate to strong SW winds are creating wind slabs in alpine and treeline areas and beginning to over load cornices. 10-25 cm of recent snow sits over a melt freeze crust on solar aspects with some facets at the crust interface. So far the lower snowpack has few concerns except for basal facets in shallow areas.
Weather Forecast
Temperatures will remain below freezing on Tuesday as 15 to 25 cm of new snow arrives with moderate to strong west winds. Precipitation will drop off on Wednesday but expect the winds to remain in the moderate to strong range for the next few days.

Wind slabs and wind effect will increase on Tuesday with the arrival of new snow and continued W winds. We expect to see increased natural avalanche activity, especially as cornices get over loaded and fail, and human triggering will be likely.
