Saturday: Overcast conditions, light SW winds, FAFL around 1700m. No significant snowfall until tomorrow evening.
Terrain exposed to previous gale winds has the rain crust at the surface. Assess before ending up on steep slope, a set of crampons and an axe may come in handy.
High
None reported in the past 48 hours.
There has been very little change in snowpack the past 10 days. Old wind deposits in sheltered terrain across the Nor Easterly 1/2 do remain. In places, these are up to 50cm deep, very stiff/hard and easily identified . Elsewhere, the rain crust from July 15th will still be exposed. Underneath the rain crust, there is no significant layering of note, with the snowpack well consolidated through to ground.
