Avalanche Summary
No new avalanches were observed today in the Burstall Pass area.
Snowpack Summary
Recent winds have created some wind slabs in the alpine, especially on lee sides of mountain passes and cross loaded gullies. The snowpack varies a lot. Thicker areas at tree line and above with close to 100cm of snow have a much denser and stronger snowpack while most areas below tree line have 40-50cm and consist mostly of facets(sugar snow).
The weak basal facets are still a concern and have a potential to be triggered from thin snowpack areas which are still plentiful at this time.
Forecasters were in the Burstall Pass area on Monday. This area is an anomaly because there is more snow than anywhere else in the Spray. This in turn has created a more dense and stronger snowpack.
Weather Summary
Tuesday will be mostly cloudy with moderate to strong West winds. Alpine temperatures will reach -5c.
