WebA snowpack containing only 2% to 5% water by volume is considered low liquid-content wet snow and occurs when melt water can readily drain from the permeable snowpack structure. In this scenario, the solid, liquid, and vapor phases are present, creating solid-solid, solid-liquid, solid-vapor, and liquid-vapor interfaces.
