Isolated weak layers in the old snow
Avalanche danger is low. Inside the old snow at high altitudes are weak layers. Isolated danger zones are found esp. in rigeline terrain in gullies and bowls where there has been more snowfall. Small slab avalanches can be triggered particularly by large additional loading. In addition, small snowdrift accumulations near ridgelines and in wind-loaded zones at high altitudes can be triggered still. Glide-snow avalanches are possible on steep grassy slopes.
At low altitudes there is still very little snow. Above 1300 m the snow depth is 30-60 cm. Inside the old snow are often expansively metamorphosed (faceted) layers sandwiched between crusts which can be triggered. At higher altitudes there are snowdrifts lying deposited atop loose layers of snow. At low altitudes the snow is moist. On Thursday, a thin melt-freeze crust could form.
Little change in avalanche danger levels is anticipated.
