The objective of this paper is to clarify the time series characteristics of the maximum depth of snow, cover (S<SUB>max</SUB>) in Akita City located in the northwest of Honshu island, from view-points of various statistics calculated from long-term data of S<SUB>max</SUB>. To understand the regionality of snow cover depth, various meteorological data are also used. From the results of correlation analysis of these data, accumulation of daily snow depth (√S<SUB>t</SUB>) and snow covered days more than 10cm of snow depth (D<SUB>10</SUB>) are most correlated to S<SUB>max</SUB>. Snow disasters in this city, will appear when the √S<SUB>t</SUB> and the D<SUB>10</SUB> exceed 55 and 70, respectively. In this time, all S<SUB>max</SUB> data more than 80cm exist within the above mentioned region. This value tends to appear within the standartd deviation (σ) of strong windy days beyond 10m/sec. According to the Gumbel distribution, this value appears probably every 10 years.
