Reactive storm slabs will be building throughout the day; pick conservative terrain.
An increase in hazard is expected if precipitation changes from snow to rain at upper elevations.
New storm slabs overlie a variety of surfaces, including a thin sun crust on solar aspects and old wind-pressed snow in wind-exposed areas. These slabs will be most reactive during periods of rapid loading from new snow, rain, or wind.
No recent avalanches have been reported. However, observations are extremely limited in this area.
If you're heading out into the backcountry, please consider sharing your observations on the MIN.
New snow combined with strong winds is forming dense, and potentially wet slabs near and above treeline. In wind-exposed areas, new snow is expected to have redistributed into lee features, forming more reactive slabs.
Around treeline, an estimated 30 to 80 cm of snow sits on a crust that extends to the ground. The snowpack diminishes rapidly below treeline.
