Flurries and wind may form reactive pockets at upper elevations. Carefully evaluate your line before you commit to it.
Summary
Confidence
Avalanche Summary
No recent avalanches have been reported. Stormy weather with flurries and gusty winds is expected to elevate the avalanche danger, increasing the likelihood of human-triggered avalanches.
If you visit the backcountry, please submit your observations to the Mountain Information Network.
Snowpack Summary
Rain, wet snow, and flurries accumulating through Friday morning have formed reactive pockets of dry(ish) snow at upper elevations and moist surfaces lower down.
Strong southerly winds are expected to build thicker and more reactive wind slabs on lee northerly slopes near ridgetops. At upper elevations, fresh snow covers a widespread thick and supportive crust formed during last week's warm sunny weather.
Wet surface snow or an isothermal snowpack may be found below the rain/snow line, which is expected to rise up to 1400 m throughout the day.
The mid and lower snowpack is generally settled and strong, with no concerns at this time.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs are most reactive during their formation.
- Use ridges or ribs to avoid areas of wind loaded snow.
Problems
Wind Slabs
Recent snow and flurries have accumulated upwards of 15-30 cm. Wind has built up large cornices and formed reactive pockets around open ridgelines where dry snow prevails.
Aspects: North, North East, East, West, North West.
