Points saillants

Start on small features and retreat to mellower terrain if you find signs of instability.

Consider the consequences of any fall in steep or exposed terrain.

    Human triggered avalanches are possible in the recent snow. The recent snow will be most unstable where you find the deepest deposits, or where it is dense and moist, and not sticking well to the old, hard surface.

Avalanche Summary

No recent avalanches have been reported.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

Recent snowfall amounts above treeline have varied across the forecast area, expect the deepest soft snow to be on the west island, and the shallowest on the east, with the north and south being somewhere in between. With fluctuating freezing levels, rain around treeline has likely made the snow shallower, denser, and wetter. At high elevations, any recent soft snow covers a hard, frozen crust.

Below the crust, the rest of the snowpack is generally settled and well-bonded.

Below treeline, the snow is moist or wet and slopes are largely below the threshold for avalanches.

Weather Summary

Monday Night

Cloudy. Light to moderate rain, generally 0-5 cm of snow expected above 1200 m, with 8 to 15 cm on the west and south island. Strong southwest ridgetop wind. Treeline low around -3 °C

Tuesday

Mostly cloudy. Light rain, 0 to 3 cm of snow expected above 1200 m. Moderate west ridgetop wind. Treeline high around 0 °C.

Wednesday

Mostly cloudy. 0 to 1 cm of snow expected above 1000 m. Light to moderate southwest ridgetop wind. Treeline high around 2 °C.

Thursday

Cloudy. Generally 0 to 2 cm of snow expected above 1000 m, with 10 to 15 cm possible on the north and west island. Moderate to strong southwest ridgetop wind. Treeline high around 0 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
