Snow Water Equivalent (SWE)
SWE is commonly used for measuring snowpack. This is how much water would be measured if the snow on the ground was completely melted.
Snow Water Equivalent (SWE) Percent of Normal
This represents current basin-wide SWE values compared to average values for this date. Values above (below) 100% represent more than (less than) average snowpack for this date.
