    As a spring snow, the water content was VERY high. Standard SWE (snow water equivalent) is typically 12:1 or 10:1 inches. This snowfall’s SWE was much higher. If some of these totals (>30 inches) had fallen as a drier more typical snow, it’s conceivable the final snowfall total would be perhaps double or triple the official measurements—enough to bury homes in snow drifts to the second story in height.
