At high altitudes, the fresh and drifted snow from the last few days is lying on an old snowpack that contains coarse-grained weak layers in its upper part, especially on north- and east-facing slopes.
As a result of solar radiation, moist snow slides from the new snow are to be expected. In many regions this is likely to occur on Tuesday afternoon, while in the northeast some may not happen until Wednesday.
