Show Know The Weather Is an inch of rain a heavy rainfall? How does it compare with an inch of snow? AN INCH of rainfall, is a very heavy rain. Over a one-acre one-acre parcel of land, an inch of rain means 603 45--gallon barrels of water have been released, or 27,1-43 gallons of water. An inch of snow, however, does not constitute a heavy release of water from the clouds. It is estimated that ten inches of snow are required to equal, in water content, one inch of rainfall. THUS, AN eight or ten inch snowfall actually represents less than an inch of precipitation, precipi-tation, measured in water or ram, which some of us hadn't realized. |
