Abstract: For more than 10 years MeteoSwiss provides warnings in case of heavy snowfall in the Alps. It helps the Swiss Institute for snow and avalanche research and the responsible people for road and railway circulation to assess the risk of big avalanches and to make their decisions. But a forecast of any extreme event is very difficult. This poster shows how forecasters of MeteoSwiss manage this problem, from climatological aspects to typical weather situations and model results. It will also be shown how quality varies in different parts of the country as well as quality has developed in the last 10 years.
