Low danger doesn't mean you get to turn off your brain. Normal cautions will help you to manage lingering wind slabs, looming cornices, and the daily cycle of loose wet avalanche conditions.

Freezing level to 1200 metres with alpine high temperatures around -1.

Avalanche Summary

No recent notable avalanches have been reported.

Snowpack Summary

A mid-week storm brought up to 15 cm of new snow to the alpine while rain saturated the upper snowpack at treeline and below. Surface conditions on solar aspects and below about 1500 metres have been affected by daily melt-freeze cycles. In the limited alpine terrain where the recent precipitation fell as snow, lingering wind slabs may remain reactive to human triggering over the near term.Below any recent snow accumulations, the overall snowpack is well settled and strong. New cornices formed and old ones grew more overhanging with the snowfall at the end of last week. Cornices become more unstable during the day as the temperature rises.

Problems

Wind Slabs

Lingering wind slabs on high north slopes still need to be assessed and managed. Gather info about the depth and reactivity of new snow as you ascend. South aspects become a concern as warming destabilizes surface snow.

Expect loose wet avalanche conditions to develop over the day on south aspects.Be careful around wind loaded pockets near ridge crests and roll-overs.Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.

Aspects: North, North East, East, South East, South.
