Regions: South Coast.

Use caution on wind effected slopes at higher elevations. A thick and supportive crust caps the snowpack on most of the terrain making avalanche activity unlikely.

Weather Forecast

Wednesday night: low of -2 at 1400m. Light to moderate northwest winds and light flurries bringing trace amounts of snow. 

Thursday: Cloudy with flurries bringing trace amounts of new snow. Moderate northwest winds and freezing levels rising to 1200m.

Friday: flurries bringing trace amounts of new snow with light westerly winds. Freezing levels around 1000m.

Saturday: stormy weather with up to 20cm of snow and moderate southwest winds. High of -2 at 1200m.

Avalanche Summary

On Monday a few size one natural wet loose avalanches were observed on steep south and east facing terrain at 1200m.

No new avalanches were reported on Sunday. On Saturday, a natural rockfall-triggered loose wet avalanche was reported from a south-facing cliff band. Glide cracks were also reported to be opening up. 

Snowpack Summary

Up to 10cm of recent snow overlies a widespread crust which exists on all aspects and at all elevations. Thin new wind slabs may have formed in exposed terrain at higher elevations. 

The late-January melt-freeze crust is now down around 40 cm and is reported to be knife hard and up to 30 cm thick. This crust extends to at least the top of treeline and is generally well bonded to the adjacent snow. 

The middle and lower snowpack are considered well settled and strong.

Terrain and Travel

  • Wind slabs may be poorly bonded to the underlying crust.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Wind Slabs

Thin new wind slabs may have formed on Monday.
