Regions: South Coast.

Continue to assess the snow surface as you travel through terrain. If it is moist then wet loose avalanches could still occur.

Weather Forecast

Tuesday night: Light rain and freezing levels around 2500 m. Light to moderate south winds.

Wednesday: Mostly cloudy with 10 cm of new snow expected at higher elevations. Light to moderate variable winds with freezing levels falling to 1500 m.

Thursday: Mostly cloudy with no new snow expected. Freezing levels around 1500 m and light to moderate variable winds.

Friday: Mostly cloudy with no new snow expected. Freezing levels around 1400 m and light southerly winds.

Avalanche Summary

On Monday skiers triggered storm and wind slab avalanches up to size two. These avalanches were generally at treeline and on northerly aspects.

Snowpack Summary

Wind slabs could be found on northerly aspects at higher elevations. Moist snow will likely be found on all aspects and elevations. As the freezing level falls a crust is likely to form.

The upper snowpack contains several crust layers that can likely be found on all aspects and elevations except high north terrain. The snowpack is considered well-settled and strong below these crusts.

Terrain and Travel

Back off slopes as the surface becomes moist or wet with rising temperatures.
As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
Use ridges or ribs to avoid areas of wind loaded snow.
Be careful as you transition into wind affected terrain.

Avalanche Problems

Loose Wet

Elevated freezing levels mean that wet loose avalanches are still possible. size and likelihood of these avalanches could increase on south and west facing slopes in the afternoon if the sun comes out.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Wind Slabs

Wind slabs could still be found in high alpine terrain. Sensitivity to triggering could be greater where wind slab has formed over a crust.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
