Good riding can be found in sheltered areas, but remain vigilant in your conservative decision making, our snow pack structure does not inspire confidence.
Summary
Confidence
Avalanche Summary
No new avalanches have been observed in the last 48 hours, but visibility of the the alpine has been poor.
Snowpack Summary
10cm of new snow has accumulated over the last couple days. Extensive wind effect from strong to extreme SW winds is present in open areas, and thin crusts have formed on solar aspects and lower elevations. A layer of faceted snow above a 1-3cm thick crust is down 35-60 cm. This persistent weak layer is consistently reactive in snowpit tests and is not going away anytime soon. Well developed basal depth hoar makes up the bottom third of the snowpack. HS ranges from 80 to 130cm.

Parker Ridge - Tuesday
A mix of sun and cloud with isolated flurries.
Precipitation: Trace.
Alpine temperature: High -5 °C.
Ridge wind west: 15-30 km/h.
Freezing level: 1600 metres.
Terrain and Travel Advice
- Avoid exposure to overhead avalanche terrain, large avalanches may reach the end of run out zones.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Problems
Wind Slabs
Recently formed wind slabs will need some time to bond.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
This problem layer is the crust and facets created by early February's warm spell. It is down 30-80 cm in the snowpack and is a 1-10 cm thick crust or multiple crusts with a layer of weak facets above.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Deep Persistent Slabs
The base of the snowpack is inherently weak and untrustworthy. Tickling this deep layer would result in a high consequence avalanche. Any avalanche in the upper snowpack has the potential to step down to the base of the snowpack.
Aspects: All aspects.
Elevations: Alpine, Treeline.
