Kernpunkte

Start on small, mellow slopes and watch for signs of instability before approaching steeper or larger slopes.

The recent snow may not be sticking well to the hard, smooth crust that it buried.

    Recent storm snow and southwest winds continue to build reactive slabs. This recent snow may slide easily on a hard, slick, buried crust. Avalanches are expected be larger and more likely on west through north facing (leeward) slopes.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches have been reported.

Looking forward, new snow and wind are expected to make human triggered avalanches likely on Wednesday.

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

Snowpack Summary

Another 25 to 35 cm of new snow is expected by the end of the day on Wednesday. Extreme southwest wind through the night, and moderate to strong wind through the day is expected to form deeper, more reactive deposits in leeward terrain.

A widespread thick and hard crust that exists everywhere except the highest alpine terrain is now expected to be 30-60 cm deep. The recent snow may not bond well to this crust.

Older crust layers, now buried 100 to 200 cm deep, are no longer a concern, and the lower snowpack is generally strong and bonded.

Weather Summary

Tuesday Night
Cloudy. 15 to 20 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1800 m, dropping to 1000 m through the night.

Wednesday
Cloudy. 10 to 15 cm of snow. 30-50 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Thursday
Mostly cloudy. 3 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Friday
Mostly sunny. 1 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
