Choose conservative, low consequence terrain and give the storm snow time to bond
Rider triggering of avalanches remains possible, or even likely in areas that received more recent snow

Moderate
Avalanche Summary
Several storm slab avalanches up to size 2 were reported on Sunday. These avalanches were skier and naturally triggered on a variety of aspects and elevations.
Observations in the region were limited over the weekend. More avalanche activity could have taken place.
Snowpack Summary
Recent snowfall amounts in the region are variable, 15 to 50 cm has fallen with strong southwest winds, forming deeper deposits on north and east aspects. This new snow overlies a crust on all aspects and elevations except north facing slopes above 1600 m. Surface hoar could also be found at this interface on sheltered features.
A weak layer, composed of facets, surface hoar, or a crust from mid February, is found 50 to 100 cm deep.
The remaining snowpack is well-settled and strong.
Weather Summary
Monday Night
Mostly cloudy with up to 10 cm of snow. 20 to 40 km/h south ridgetop wind. Treeline temperature -9 °C.
Tuesday

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Don't let storm day fever lure you into consequential terrain.
- Be aware of the potential for large avalanches due to buried weak layers.
- Make observations and continually assess conditions as you travel.
Problems
Storm Slabs
Storm slabs will likely remain rider triggerable. Assess new snow amounts, the more you find the larger and more sensitive slabs will be.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
The mid February layer could still be rider triggerable, especially where a thick crust isn't found above it or in shallow rocky terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
