In sintesi

Spring returns to the island yet again with sun and warming.

You may find deeper snow in isolated areas around the North and West island.

    Wind slabs are most likely to be found on slopes that are leeward to recent southwesterly winds.

    Even a small wet loose avalanche can have severe consequences when combined with a terrain trap such as a cliff. Stay aware of your position, as the sun’s effects can be rapid.

Confidence

Moderate

  • We are uncertain due to the track and intensity of the incoming weather system.
  • The snowpack structure is well understood.

Avalanche Summary

On Thursday, a few small storm slab and loose wet avalanches were reported.

Strong solar input and changing temperatures are rapidly changing conditions. Continue to assess conditions as you travel.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

30–60 cm of new snow has accumulated at treeline and above so far this week. Expect to find this new snow deeper mid island and south, with the north island seeing lesser amounts. Moderate south or southeast winds will have transported it making deeper, denser deposits in leeward terrain.

Steep south through west facing slopes have a thin, breakable crust that is now down close to 25 cm.

The thick and strong mid-March crust is now expected to be buried by 40-70 cm of mostly settled snow, with the deeper areas being found on the north and west island.

Below this, the rest of the snowpack is wet but well settled and strong.

Terrain and Travel Advice

  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
