    Evidence from recent snowpack tests and whumphing would suggest that a weak layer of facets persists down 20-50cm in some areas, and may be becoming reactive with incremental loading from recent small snowfalls.

Weather Forecast

A trough strengthens offshore in the Aleutians on Monday morning. This will push cool and unsettled air over our region. Monday: A mix of sun and cloud with isolated flurries. Precipitation: Trace. Treeline temperature: Low -9 °C, High -4 °C.Ridge wind: light West. Freezing level: 1700 metres.

Snowpack Summary

Light snowfall and moderate SW wind building pockets of slab in the alpine. A supportive crust exists to 2,100m on all aspects and extends into the alpine on solar slopes. A winter snowpack remains on N alpine aspects, with a weak faceted layer down 20-50cm remaining a concern, and a facetted mid/lower snowpack that is weak in shallow areas.

Avalanche Summary

No new avalanche activity has been observed or reported.
