Відповідь:
There are different types of avalanches: from fluffy snow - dry, wet and wet; from a snowboard (i.e. from snow compacted by the wind); combinations of the above types.
Avalanches come down at any time due to the detachment of snowboards, which can also occur in the depth of the snow cover. Eaves - protruding snowdrifts on the crests of ridges - behave like snow boards.
Good weather with or without sunshine, accompanied by a rapid rise in temperature and following a snowstorm. These conditions favour the formation of wasps caused by exposure to sunlight and snowboard avalanches caused by melting.
