Use caution around wind-loaded areas at upper elevations, where wind slabs have formed over a crust.
Though natural avalanche activity has tapered off human triggering remains possible.
Moderate southerly winds have redistributed 20 - 40 cm of available snow into deep pockets in lees. Wind slabs overlie a crust and may be reactive to human triggering.
No new avalanches were reported throughout the weekend. On Friday a size 1.5 skier remote storm slab avalanche was reported. This slab was 25 cm deep and released on a steep northeast slope at 1400m. Several other avalanches like this one were reported to have occurred on Friday. triggers included ski cuts and naturals. Check out this MIN from Mt Washington.

30 to 40cm of recent storm snow is settling over a melt-freeze crust above 1000 m. A thin layer of facets could exist around this interface. Strong southerly winds have redistributed available snow into deep wind slabs on north and east aspects and cross-loading on others. Below 1000m the snow surface could still be moist.
Terrain below treeline has limited or no coverage.
