Points saillants

Rideable lines remain on north and east facing slopes, particularly in gully features. Watch for small but reactive slabs forming in these features.

    Small but reactive wind slabs may develop on Sunday, and again on Tuesday. With rapidly falling temperatures, slabs may not bond well with the old snow surface.

Moderate

Avalanche Summary

Several small cornice-triggered avalanches were observed in the Tablelands on Wednesday.

Fresh wind slabs forming on Sunday and Tuesday are likely to be reactive to human triggers.

Snowpack Summary

Many south and west-facing slopes are snow-free, except for gullies. North and east-facing terrain may still have enough coverage for riding and threshold depths for avalanches. In these terrain features, small wind slabs are expected to form over a snowpack that consists of crusts and refrozen snow.

Weather Summary

Saturday Night

10 to 15 cm of snow, with 70 to 100 km/h southwest wind. Freezing levels remain at sea level. Alpine temperatures around -4 °C.

Sunday

Mostly cloudy skies, chance of clearing in the afternoon. 60 km/h northwest wind ease over te day to 40 km/h. Alpine temperature -3 °C.

Monday

Mix of sun and cloud. 30 to 50 km/h northwest wind. Alpine temperature -8 °C.

Tuesday

Cloudy with up to 15 cm of snow/15 mm of rain possible. 60 to 80 km/h southwest wind. Alpine temperature around 0 °C as freezing levels rise toward 1000 m. .

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Make observations and continually assess conditions as you travel.
