Heavy snowfall and strong wind will create dangerous avalanche conditions.
Seek out lower-angled, sheltered terrain for the best and safest riding.
Heavy snowfall and strong southwest wind will build fresh storm slabs that may be deepest and most reactive in wind-loaded areas.
Storm slabs may overlie a weak layer, which could result in wide propagation and remote triggers.
No recent avalanches have been reported, but observations are limited. We expected heavy snowfall and wind on Monday to form fresh slabs that may fail easily on buried weak layers. Learn more in our recent conditions update.

Up to 30 cm of new snow is expected to fall on Sunday. This new snow adds to the 10 to 20 cm of snowfall that has accumulated over the past 4 days. Strong southwest wind will redistribute new snow in wind-exposed areas.
This new snow may be sitting on a weak layer of surface hoar, facets and/or a crust formed during the recent cold, clear weather.
Data is limited at this time of year, but to our knowledge, the mid and lower snowpack remains generally well-bonded, containing several crusts from earlier in the season.
Average snow depths at treeline range from 60 to 100 cm and decrease dramatically at lower elevations.
