Highlights

A fine Thursday. NW begins to fill in on Friday. Enjoy the fine weather!

Avalanche problems

  • Wind Slabs

    • All elevations
    Likelihood
    Possible
    Size
    1

    Wind Slabs will be possible to trigger at upper elevation bands across the SE 1/2 above 1800m. Obviously wind loaded terrain, blowing snow and recent avalanche activity are all indicators of heightened danger.

  • Loose Wet

    • All elevations
    Likelihood
    Likely
    Size
    1

    Loose Wet avalanche will be likely in steep, rocky terrain on the NW 1/2. These will only be a problem in the afternoon as sun and an increase in temperatures impact recent snow. Look for roller balling or recent avalanche activity as a key sign of instability.

Recent Avalanche Activity

1x Size 1 Wind Slab was explosive triggered by Mt Hutt Patrol on Monday morning. This was in a steep, unsupported SE facing slope at 1900m.

Current Snowpack Conditions

25cm of recent snowfall has bonded well to the old snow surface. This is capped by a rain crust which developed on Tuesday night. There are still wind deposits up to 30cm deep in lee or cross loaded terrain features. Prior to this the snowpack resembled one you would see mid September or October.

Mountain Weather

A fine Thursday. Light wind and a FAFL lowering to 2100m. Friday, NW winds fill in and overhead cloud increases. FAFL rises to 2700m.

Sliding Danger

Surfaces are hard given recent freezing rain. Crampons and an axe are recommended.

Forecast Confidence

High

  • We are confident due to a stable weather pattern.
