Watch for unstable snow on isolated terrain features. Although triggering slabs on deeply buried weak layers is unlikely under the current conditions, we'll be avoiding rocky start zones and thick to thin transitions for the remainder of the season.
No significant avalanches have been reported in the past few days. If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
5 to 15 cm of new snow has fallen on wind-pressed surfaces in the alpine and crust on solar aspects around treeline. Soft older snow may be found in shady, wind-sheltered areas. Weaknesses in the mid and lower snowpack are unlikely to produce avalanches under the current conditions. A weak layer of surface hoar/crust/facets buried in early January is now over 1 m deep in most areas, and has not produced avalanche activity for several weeks. The lower snowpack consists of basal facets, particularly in thin snowpack areas.
Cloudy, flurries easing with 2 to 4 cm of snow, 20 km/h southeast wind, treeline temperatures cool to -10 °C.
Mostly cloudy, isolated flurries with trace amounts of snow, 10 km/h south wind, treeline temperatures around -6 °C.Sunday
Mix of sun and cloud, no significant precipitation, 15 km/h southwest wind, treeline temperatures around -8 °C.Monday
Sunny, no precipitation, 20 km/h northwest wind, treeline temperatures around -6 °C.

Terrain and Travel Advice
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Pay attention to isolated alpine features as well as cross-loaded features at treeline.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
With only 5 to 15 cm of recent snowfall, if a wind slab problem exists it will be confined to isolated pockets in the alpine.
