How much water is 12 inches of snow?
Commonly, the percentage of water to snow is called the “snow ratio”. An old rule of thumb was that for every 10 inches of snow, there would be 1 inch of water (10:1). However, this is far from the norm, and recent studies indicate that a 12:1 ratio might be more representative (on average) for the Upper Midwest.
How much water is in a foot of snow?
More average snow may weigh 15 pounds per cubic foot and drifted compacted snow may weigh 20 pounds or more…” Let’s figure this out… There are 7.48 gallons per cubic foot of water – that’s about 62.4 pounds.
How do you measure water content in snow?
This measurement is made by melting the snow that has fallen in the precipitation gauge and measuring the liquid as is done for rainfall. Water content also can be measured by taking a core sample of the snowfall from the SMB or other measurement surface.
How much water is 2 inches snow?
An inch of snow falling evenly on 1 acre of ground is equivalent to about 2,715 gallons of water. This figure, however, based upon the “rule-of-thumb” that 10 inches of snow is equal to 1 inch of water, can vary considerably, depending on whether the snow is heavy and wet, or powdery and dry.
How much snow is 4 inches of rain equal to?
So, at 3 °F, 4 inches of rain is equivalent to 160 inches of snow.
How much water is in 8 in of snow?
More densely packed and wet snow is in the ratio of 8 inches of snow to 1 inch of equivalent rainfall, and more powdery snow is about 14 to 1 ratio. Obviously this is an approximation but a good one.
How long does it take 3 inches of snow to melt?
Three days of temperatures at 50 degrees can melt 2 to 4 inches of snow. If temps fall below freezing at night, the process will be slower. The amount of moisture in the air can accelerate the melting process, while wind will carry away the moisture and preserve the snow pack.
Can it snow at 40 degrees?
In fact, snow can fall at temperatures as high as 50 degrees. Most residents of the northern United States have probably seen 40-degree snowfalls before, but snow at temperatures greater than 45 degrees is hard to come by. … When moisture overlaps with below-freezing temperatures at cloud level, snowflakes can form.
