Where dry snow accumulates, check for wind slabs around ridges and leeward terrain.
Where there's dry snow (at the highest elevations), check for wind slabs around ridgelines and in leeward terrain.
Where dry snow accumulates, check for wind slabs around ridges and leeward terrain.
Wet loose avalanches are possible at lower elevations where the snowpack is moist or saturated from rain, or where new snow sees sun and warming for the first time.
Looking forward, we expect small wind slabs may have formed at upper elevations.
Small loose wet avalanches out of steep terrain on northwest-facing slopes were reported on Thursday around Mt Washington.
5 cm of new snow falls on 20 cm of moist snow at upper elevations and a wet and unconsolidated upper snowpack below 1100 m, from above-freezing temperatures and rain.
A robust crust, formed in early March, can be found in the mid-pack. The snow above is well bonded to this crust. Below this, the snowpack is well consolidated and strong.
