Snow Depth Analysis and Snowfall Amount Analysis data are issued every hour with a spatial resolution of 5 km. Snow Depth Analysis is based on (1) a model simplifying temporal variations in snow properties (e.g., compression and melting) with inputs of precipitation, temperature and other variables, and (2) modified model output based on AMeDAS data.Snowfall Amount Analysis is based on increments between current and previous snow depths.

Snowfall Amount Analysis is based on increments between current and previous snow depths.
Very Short-range Forecasts of Snow are issued every hour to predict snow depths and amounts over the next six hours with a spatial resolution of 5 km, with depths derived from the model used in Snow Depth Analysis. These inputs are from Very Short-range Forecasts of Precipitation, and from temperature and other variables based on LFM. The initial state of snow layers is based on Snow Depth Analysis, and snowfall forecasts are based on hourly increments of predicted snow depth.
