Watch for rapidly changing conditions on sun affected slopes - recent storm snow may slide easily on the crust below.




Avalanche Summary

Last reported avalanches were from explosive control work on Thursday, producing size 1-2 wind slabs in north facing treeline terrain. Crowns were thin, however wide propagation was reported.

Moving forward we expect wet avalanches to be most likely on sun affected slopes.

Snowpack Summary

Up to 25 cm of recent snow can be found over a widespread crust. Surface snow is expected to become moist or wet with rising temperatures and sun, on steep south facing slopes the crust below may also break down.

The snowpack below the crust is strong and bonded.

Weather Summary

Saturday Night.

Mostly clear skies. 10-20 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level drops to 1000 m.


Clear skies. 30-50 km/h northeast ridgetop wind. Freezing level rises to 3000 m, bringing treeline temperatures to +10 °C.


Freezing levels remain around 2800 m overnight and throughout Monday. A mix of sun and cloud. 30 km/h northwest ridgetop wind. Treeline temperatures around +9 °C.


Freezing levels remain around 2500 m overnight and throughout Tuesday. Clear skies. 40 km/h southwest ridgetop wind. Treeline temperatures around +7 °C.

Terrain and Travel Advice

  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches


Loose Wet

Potential for wet avalanche activity (slab and loose) increases as temperatures rise, but concern is greatest on steep, sun affected slopes. Avalanches may initiate easily on the smooth crust below.
