Abstract: NXDAYS, the non-parametric avalanche forecast model, is discussed in the context of historical development of multivariate, multinormal discriminant type models. Three years of experience permit the reviewing of its performance. To distinguish avalanche days from non-avalanche days, the critical level is 0.3, i.e. if 3 or more out of 10 nearest neighbors are avalanche days, the actual day to forecast will also be an avalanche day. Problems with data acquisition, data-and parameter sets, as well as forecast models are mentioned.
