Stick to simple terrain free of overhead hazard as storm slabs build and temperatures rise, natural avalanches are possible
Expect increased reactivity on wind affected features. Storm slabs may involve moist/wet snow with possible rain, and rising freezing levels.
No new avalanches have been reported. However, observations are limited. We expect storm snow to be reactive to rider traffic, and possible natural avalanches in wind loaded features.
If you are out and about in the mountains, please consider posting your observations to the MIN.
By Wednesday afternoon 20-30 cm of snow is expected, adding to the previous 10-20 cm of dense/wet storm snow. Higher elevations are likely wind-affected with deep deposits on north and east facing ridgelines. Lower elevation snow will likely be moist from rain or mixed precipitation.
A mid-November crust sits 30–50 cm deep. Below it, the snowpack contains multiple crusts, and in some areas a weak, sugary facet layer exists near the ground.
Snowpack depths range from 30–100 cm, thinning quickly at lower elevations. In many areas, especially below treeline, slopes lack enough snow to cover ground roughness and produce avalanches.
