Summary
Confidence
High - Benign weather forecast.
Travel & Terrain Advice
A modest accumulation of new snow overlying recent melt freeze crusts and associated wind may produce reactive wind slabs on NW-NE aspects at treeline and above. Many slopes will remain firm and/or have breakable crusts. Variable surface conditions treeline and below and wind loaded pockets in the alpine are the main hazard concerns.
Avalanche Summary
Loose wet natural activity to size 1.5 observed on solar aspects on Alexandra Peak from steep rock faces.
Snowpack Summary
Up to 5 cm of new snow above 1400 metres and rain below on previous old moist surfaces. Strong SE winds have plastered this new moist snow to windward slopes. Recent warming and high freezing levels have had a minimal impact with upper snowpack temperatures remaining cool. Mid and lower snowpack very well settled.
