Short summary
We examined how avalanche forecasters across Europe use the EAWS (European Avalanche Warning Services) Matrix, a decision-support tool for determining regional avalanche danger levels. Although warning services apply the Matrix differently, we identified both consistent patterns and notable inconsistencies in its application. Our findings highlight where the Matrix works well and where clarification is needed, supporting more consistent and transparent avalanche information for the public.
