Snowpack Summary
A melt-freeze crust has likely formed at the snow surface with overnight cooling. Rising temperature will start to melt the snow surface, as the day progresses, especially on steep sun-exposed slopes.
At upper elevations, up to 20 cm of moist snow can be found. Large crystals of surface hoar may still exist on sheltered features.
The mid or lower snowpack is generally well-settled and bonded.
Snow depths vary across the region. Currently, near Mt. Washington, 135 cm is reported at 1100 m, and 250 cm at 1500 m.
