Avalanche Summary
Over the last three days wet loose avalanches have occurred primarily on steep south facing (sun affected slopes) at lower elevations with rising freezing levels and strong sunshine. Cloud and cooler temperatures on Friday will reduce the likelihood of wet avalanche activity.
Rider triggered wind slabs were reported near Nelson on north facing terrain features, from previous easterly winds. Warm temperatures have likely helped these slabs to settle and bond, but reactivity may remain in isolated features.
Snowpack Summary
A melt freeze crust or moist snow exists on all aspects except on north facing slopes at high elevations where new snow from last week may overlie facets and surface hoar or wind affected surfaces. Southwest winds forecast for Friday will have limited snow to transport thanks to the melt freeze crust and moist snow. In areas where dry snow is available, small pockets of wind affected snow may form.
The mid-pack is generally well-settled.
The lower snowpack includes a layer of weak facets near the ground. No recent avalanches have been reported on this layer. However, we continue to track the layer and watch for any signs of it becoming active again.

Terrain and Travel Advice
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Make observations and assess conditions continually as you travel.
