carefully assess new snowfall amounts as you move through terrain. Convective flurries can result in localized significant snowfall and increased hazard.

Confidence

Moderate

Avalanche Summary

On Thursday explosive control produced storm slab avalanches up to size two. No other significant avalanches were reported.

Please post your field observations and photos on the Mountain Information Network. .

Snowpack Summary

20 to 50 cm of storm snow sits on wind affected surfaces at all elevations. Deeper deposits may be found in north and east facing terrain features due to southwest winds.

The mid-snowpack is generally well settled. The lower snowpack includes a layer of weak sugary crystals near the ground. These facets are slowly gaining strength and have not produced recent avalanche activity. We continue to track the layer and watch for any signs that it could wake up and produce very large avalanches.

Weather Summary

Thursday Night

Mostly cloudy with up to 10 cm of new snow possible. Moderate westerly winds and a low of -8°C at 1800 m.

Friday

Mostly cloudy with the possibility of convective flurries bringing up to 10 cm of new snow. Light to moderate westerly winds and a high of -6°C at 1800 m.

Saturday

A mix of sun and cloud with the possibility of convective flurries bringing up to 5 cm of new snow. Light southerly winds and a high of -4°C at 1800 m.

Sunday

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.

Avalanche Problems

Storm Slabs

New snow and westerly winds will likely form rider triggerable storm and wind slabs. The largest and most reactive slabs will likely be found on north and east aspects at treeline and above.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2
