Closely monitor how the new snow is bonding to the old surface. Human-triggered avalanches remain likely.
Up to 70 cm of storm snow and moderate winds have built storm slabs at all elevations. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.
On Sunday, numerous natural, size 1, wet loose avalanches were observed below treeline.
On Saturday, explosive control produced several storm slab avalanches, size 1 to 1.5, at treeline and below treeline. A few human-triggered storm snow avalanches, up to size 1, were also reported on below treeline features.
If you are headed to the backcountry, please consider sharing your photos and observations from your day on the Mountain Information Network.
Up to 70 cm of storm snow blankets the region. Moderate southwest winds have redistributed storm snow into deep pockets on lee slopes at the ridgeline. Storm snow covers a thick a crust except on high north facing terrain, where new snow buries up to 20 cm of dense snow overlying a crust from earlier in March. Below this crust is a generally moist upper snowpack.
The mid and lower snowpack contain several crusts that are not concerning.
