Dangerous avalanche conditions exist. Careful snowpack evaluation, cautious route-finding, and conservative decision-making are essential.
Up to 55 cm of storm snow and moderate winds have built reactive storm slabs at all elevations. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.
No new avalanches were reported by 4 pm on Sunday.
On Saturday, several human-triggered size 1 storm slab avalanches were reported on north and west facing slopes below ridgecrests.
If you are headed to the backcountry, please consider sharing your photos and observations from your day on the Mountain Information Network.
30 to 55 centimeters of storm snow blankets the region. Ongoing 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 5 to 20 cm of dense snow overlying a crust from earlier in March.
The mid and lower snowpack is strong and dense.
