Weather for Avalanches


One avalanche that happened was the Taranaki Avalanche. When this happened a lot of snow piled up and the weather was warm but had a lot of rain. Then when it happened people had said that " it has reached its point and can no longer be stable." So people were about 5000m down from the avalanche and they saw the snow slipping off the mountain top creating a huge avalanche.

You might be wondering what kind of weather produces an avalanche right? Well let me tell you wind is the most common cause.Wind can deposit snow 10 times faster than snow falling during storms. Wind erodes the snow from the unwind side of obstacles and deposits snow on the downwind sides. We call this "wind loading". This added weight can also cause avalanches. Meanwhile, rain or melting snow on the surface and too cause avalanches. But wind, snow or rapid warming don't always produce avalacnhes. It depends on the condition of the snow and the conditions during a storm. With the snow stable , even heavy,new snow with wind can bond well and be perfectly safe in the right conditions. - I_Rule_U_Dont I_Rule_U_Dont May 17, 2007 Angelica F. Per.1

Avalanch warnings:
  • They have a hazard scale they use to see the weather
( People use the hazard sclae for snow stability)
  • there is heavy rainfall and snowfall
  • the winds are getting stronger
  • In Switzerland they call as much people as hey can to warn them if there are avalanches.
