Enjoy the ongoing sunshine but continue to practice safe travel habits.
Be wary of the lurking persistent and deep persistent problems. These problems are best managed by choosing conservative terrain.

Avalanche Summary
No recent avalanches have been observed.
Snowpack Summary
Suspect a suncrust formed on the surface on solar aspects to 2300m or higher from recent clear days. 15-25cm of snow overlies the Feb 3rd crust, which ranges from 1-3cm thick in the alpine. On shaded aspects it exists up to 2500m and is breaking down due to the cold temperatures. On solar aspects it is up to 2800m. At lower elevations it is 15-20cm thick. The Persistent and Deep Persistent weak layers continue to produce whoomphing and sudden fractures in tests.

Saturday
Sunny with cloudy periods. No precipitation. Light wind. Alpine temperature, High -2 °C. Freezing level 2000 metres.
Sunday

Terrain and Travel Advice
- Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
- Minimize exposure to overhead avalanche terrain, large avalanches may reach the end of runout zones.
Problems
Persistent Slabs
This weak layer, buried 20-40cm deep, is still reactive in snowpit tests and human triggering remains possible, particularly in shallow rocky start zones.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
The base of the snowpack is inherently weak and untrustworthy. Human and natural triggering of these basal facets remains possible.
Aspects: All aspects.
Elevations: Alpine, Treeline.
