About This Map
Snow depth is the amount of snow on the ground at a given moment. Snow depth change is the change in snow depth in a given period. Snowfall increases snow depth, causing snow depth change to be positive; and melting and compaction decrease snow depth, causing snow depth change to be negative. On our weather maps, snow depth and snow depth change are given in centimeters or inches.
