jesse milner,
Early season hazards are very present at the moment. Reverse loading could have built wind slabs on the southerly aspects.
Summary
Weather Forecast
Sunday: Sunny with cloudy periods. Alpine temperature: High -9 °C. Ridge wind northeast: 10 km/h. Freezing level at valley bottom.
Monday: Cloudy with sunny periods. Alpine temperature: Low -13 °C, High -10 °C. Ridge wind west: 15 km/h. Freezing level at valley bottom.
Snowpack Summary
Treeline has a snowpack of 30-40cm with overall supportive travel. 10-15cm of recent snow has been redistributed from moderate northerly winds and overlies a rain crust which exists up to 2200m. Winds have formed wind slabs and wind effect on S through E aspects at ridge top. Below treeline the snow remains below threshold values.
Avalanche Summary
There were no results from Thursday's explosive control on Parkers slabs. Friday's patrol noted one size 2.5 wind slab in the alpine on large east facing rock slab, It appeared to be cornice triggered, started loose and resulted in a slab lower down. Several other size 2 wind slabs were observed in alpine E aspects that near ridge tops.

Problems
Wind Slabs
On Nov 4th the zone received 10-30cm of warm snow with S shifting N winds creating some slab conditions. The season is just beginning so treat all slopes conservatively until more information is gathered.
- Early season hazards such as rocks, trees and stumps are still visible.
Aspects: North East, East, South East, South, South West.
Elevations: Alpine.
Likelihood
Expected Size
Loose Dry
The storm snow on North steep aspects is lacking cohesion and can result in loose dry avalanches.
- Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.
Aspects: All aspects.
Elevations: Alpine.
