Sammendrag
Avalanche exposed settlements, communication lines, ski resort operations, construction
sites, tourism and professional guiding are only few examples of activities in the mountains where an
active risk management requires local avalanche warnings. While regional avalanche warning is somehow
standardized by the rules and standards of the European Avalanche Warning Services (EAWS),
local avalanche warning services use a great variety of methods and tools both in the avalanche hazard
assessment and in the communication of the results. To gain an overview of the different practices in
Europe, the EAWS established a working group on local avalanche warning. The aim of the working
group is to establish a general definition of local and regional avalanche warning and to outline the state
of the art in Europe. A questionnaire in six languages was circulated in Europe to target local avalanche
services collecting more than 200 answers. The analysis of the survey shows a large variety between
local avalanche services, very different set-ups and applied methods for assessing and communicating
the local avalanche danger. Based on the results of the questionnaire, a first definition of local versus
regional avalanche warning assessment is presented.
