The article presents the research results of the actual snow load and its security on the basis of the statistical data distribution of the annual maximum water storage in snow, obtained at the weather station Kolomna. The analysis of the implementation of the annual maxima of snow load according to data from 13 weather station located in different snow areas. Indentified all necessary statistical characteristics of the snow load, and the parameters of the law of Gumbel distribution for each snow district. The results of the research concluded that the known desing values of snow loads given in normative documents can be quite simple to obtain the statistical moments of a random variable its one-year highs and the parameters of the Gumbel law. The obtained characteristics are the initial data when conducting a probabilistic analysis of structures and evaluation of their safety and durability.
