Current Snowpack Conditions

Significant warming and softening of surfaces occurred in most terrain Sunday afternoon. Above 1800m, Wind deposits from Saturday nights snow remain in sheltered terrain across the Easterly 1/2. In places, these are up to 30cm deep. Elsewhere, the rain crust from July 15th will still be exposed. At lower elevation bands and under the rain crust the snowpack is very well consolidated & spring like.

Mountain Weather

Tuesday: A fine day. Light Westerly 1/4 winds. FAFL up to 2300m.

Sliding Danger

If surfaces freeze overnight expect a firm start. Crampons and an axe will be required. As some warmth and some sun impact the snowpack this hazard will cease to exist.

Forecast Confidence

High

  • The snowpack structure is well understood.
