Storm snow likely remains rider triggerable. Watch for deeper and more reactive deposits in wind affected terrain and remember surface hoar may be present in sheltered terrain

Moderate
Avalanche Summary
A mix of conditions produced a variety of avalanches on Saturday, with loose wet at low elevations, and loose dry or storm slab at higher elevations where snow remained mostly dry. With more snow received Saturday night, we expect avalanche activity to have increased.
Snowpack Summary
Around 30 cm of storm snow has fallen in the last 3 days. Low elevations received mostly rain with wet snow at higher elevations. This sits over a mix of sun crusts, surface hoar in wind-sheltered terrain, and wind-affected snow.
The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.
Weather Summary

Tuesday
A mix of sun and cloud. 30 to 40 km/h west ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Storm Slabs
The new snow will take time to bond to the old snow surfaces. In wind sheltered and shaded terrain preserved surface hoar may be present, increasing reactivity.
