Approximately 10 to 40 cm of recent snow has accumulated since last week, accompanied by generally southerly winds. This snow has buried a widespread melt-freeze crust below roughly 1200 m, and a variety of old, firm wind-affected surfaces above.
A crust buried on January 26th is down 50 to 80 cm from the surface. On north through east aspects, a layer of surface hoar may exist atop the crust.
A layer of weak facets from December lingers anywhere from 100 to 300 cm below the surface. Although very unlikely to be triggered, some concern remains in shallow areas of White Pass and inland regions with a thinner snowpack.
