EAWS Matrix
The EAWS Matrix is a tool used by the European Avalanche Warning Services to determine the regional avalanche danger level. It helps the forecaster to assess the avalanche danger more objectively and thus increases the consistency of the danger level across borders.

Avalanche Danger Scale
In 1993, the European Avalanche Warning Services agreed on a common five-level avalanche danger scale, this was an important milestone in the history of the EAWS. The five danger levels were later introduced worldwide and today form the standard reference of modern avalanche forecasting.
