Recent snowfall and above freezing tempertures will make avalanches possible at upper elevations.

Avalanche Summary
No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report!
Snowpack Summary
Friday's storm brought 20 to 30 cm of fresh snow to the south and central parts of the island and less than 15 cm to northern parts. This adds to the previous storm to bring recent snowfall up to 30 to 60 cm. Above freezing temperatures over the weekend will promote settlement of this snow and cause the surface to become moist or wet.
80 to 100 cm of snow can be found in the alpine, with wind-loaded areas up to 150 cm. Every storm brings the snowpack closer to the threshold for avalanches, however some areas at treeline and most areas below treeline have yet to overcome ground roughness.
Weather Summary
Saturday night
Clear skies, no precipitation, 30 km/h wind from the northeast, above freezing temperatures between 1000 and 2000 m.
Sunday

Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Watch for signs of slab formation throughout the day.
- Make observations and assess conditions continually as you travel.
Problems
Storm Slabs
With 20 to 30 cm of fresh snow from Friday night, human-triggered slab avalanches will be possible on specific slopes. Watch for slab formation on steep, convex, or wind-loaded slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.
