What does heavy wet snow refer to?

Heavy wet snow is characterized primarily by its water equivalent ratio, which indicates the snow’s moisture content. When snow has a water equivalent ratio of 10:1 or less, it means that a relatively small amount of snow, when melted, yields a significant amount of water. This suggests that the snow is dense and contains a high volume of moisture, contributing to its "heavy" designation.

In contrast, other forms of snow such as light and fluffy snow or dry, powdery snow have different characteristics. Light and fluffy snow typically has a higher water equivalent ratio, meaning it is less dense and holds less moisture, making it easier to blow or move. Snow that falls in a dry, powdery form also indicates lower moisture content, which is ideal for skiing or similar activities due to its lightness and ability to accumulate without becoming compacted.

The high moisture content in heavy wet snow can lead to potential hazards, such as increased weight on structures, which must be taken into account in situations like snow removal and the stability of trees during winter storms. Thus, the term "heavy wet snow" is closely aligned with its moisture content and density, correctly identified by the water equivalent ratio stated in the correct answer.
