What is the snow-to-water equivalent for heavy, wet snows?

The snow-to-water equivalent for heavy, wet snows is typically 10:1 or less. This ratio indicates that 10 inches of heavy, wet snow generally equals about 1 inch of liquid water. Heavy, wet snow has a higher moisture content due to the warmer temperatures and the density of the snowflakes, which results in a lower ratio compared to lighter, fluffier snow.

Understanding the properties of different types of snow is essential for various applications, such as water resource management and predicting potential flooding or runoff during spring thaws. Light, fluffy snow tends to have a higher snow-to-water equivalent (such as ratios like 20:1 or 30:1), while heavy wet snow is more compact and has greater water content, which justifies the lower ratio of 10:1 or less. This knowledge can help professionals in arboriculture and related fields make informed decisions about the effects of snow accumulation on tree health and stability.
