Avalanche Control will take place in the highway corridor commencing early this afternoon.
Avalanche Problem 1: Loose Wet
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- If triggered loose wet sluffs may step down to deeper layers resulting in larger avalanches.
- Minimize exposure to overhead avalanche terrain, especially in the heat of the day
Avalanche Problem 2: Cornices
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Cornices are large and will be primed for falling down during the heat of the day. Remember that even on a shaded aspect, the sun is still baking the back of the cornice.
Travel and Terrain Advice
- Avoid travel on slopes that are exposed to cornices overhead.
Avalanche Summary
There was a widespread loose wet avalanche cycle yesterday corresponding to daytime warming. Average size 2.5 with several size 3.5 observed. Avalanche control is planed for this afternoon in the highway corridor.
Snowpack Summary
Typical spring melt freeze conditions. This morning we had a minimal recovery with temperatures just below zero at valley bottom and likely less of a recovery higher with an overnight inversion. There may be some dry snow on North aspects above 2400m. Cornices are large and will weaken with the rising temperatures.
Weather Forecast
A ridge of high pressure dominates the weather pattern over B.C. with clear skies for the whole province. With a strong southerly flow of air, freezing levels rise to 3700m. Alpine temp will reach 8.0. Conditions stay warm until a pulse of moisture arrives Sunday with 16mm of rain by Tuesday morning.

With a weak overnight refreeze, expect to see the snowpack destabilize quickly as the temperature climbs. Yesterday we observed small snowballs that resulted in size 3.0 avalanches. Little sluffs can entrain a lot of mass this time of year.
