New wind slabs are forming from recent snow and SW winds. These will be found in lee features and sit above a weak layer of facets or surface hoar.
Rising freezing levels may be problematic for ice climbs in direct sun or with a lingering snowpack overhead. Wind slabs are developing above treeline, with most new precip and transport observed in the Icefields.
New wind slabs are forming from recent snow and SW winds. These will be found in lee features and sit above a weak layer of facets or surface hoar.
This problem is low probability but high consequence as it would be releasing near the ground thus with a lot of destructive volume. Be extra cautious where snowpack goes from thick to thin areas.
No new avalanches observed or reported in the region.
High freezing levels throughout the region support the development of a new surface crust, especially below treeline (up to 2200m). A weak layer of surface hoar and facets is down ~10cm, which is most problematic in areas with wind loading.
In open areas, recent winds have redistributed the new snow into windslabs. The midpack is still supportive, but a weaker, faceted layer lingers above the ground, creating a deep, persistent slab.
