Mt Hutt Patrol reported a Size 1 Loose Dry avalanche in steep, unsupported terrain on a SW aspect. This occurred naturally some time during the high winds on Thursday.
The snowpack has taken a hammering with winds up to 150kph on Thursday and Friday morning. Any dry snow has been deposited into very sheltered terrain. Elsewhere the rain crust from July 15th will be exposed. Underneath the rain crust, there is no significant layering of note, with the snowpack below this well consolidated through to ground.
Saturday: Up to 15cm of snow is forecast overnight Friday. Strong SW winds persist throughout. Skies clear early than otherwise fine day. FAFL 900m.
Terrain expose to gale NW winds still has the rain crust on the surface. Assess the surface before ending up on slope, a set of crampons and an axe may come in handy.
