Lingering wind slabs remain a concern in the alpine. Exercise increasing caution around solar aspects and lower elevations as loose wet avalanche conditions develop over the day.

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 seen daily change through melt-freeze cycles. In the limited alpine terrain where the recent precipitation fell as snow, lingering wind slabs will remain a concern 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.
