How much snow does 3 inches of rain make?

Baseline Rain-to-Snow Conversion

The baseline ratio of rain to snow is 1 inch of rain equals 10 inches of snow. For example, to calculate the snowfall equivalent of 3 inches of rain, multiply 3 by 10 to obtain 30 inches of snow as the baseline conversion.

How much water is in 4 inches of snow?

Volume and weight

Heavy, wet snow has a very high water content—4 or 5 inches of this kind of snow contains about 1 inch of water. Thus, an inch of very wet snow over an acre might amount to more than 5,400 gallons of water, while an inch of powdery snow might yield only about 1,300 gallons.

How much moisture is in one inch of snow?

There is a general rule of thumb that says the perfectly typical snowfall will have a snow-to-liquid ratio of 10 to 1, meaning that 10 inches/cm of snow will yield one inch/cm of water. But that’s just an average — and when is any weather event “typical?” In Colorado or Utah, they often see dry, powdery snow.

What is the average snow ratio?

10 to 1
The average snow ratio is 10 to 1 (10 inches of snow for 1 inch of liquid water), which is usually seen with temperatures near 32° or just below. However, ratios can be as low as 5:1 with bad snow growth/warmer surface temperatures and as high as 20:1 or 30:1 with temperatures in the teens and single digits.

How do you calculate snow water equivalent?

Define the dimensions of the volume of the snow sample as some base area times the depth of the snow. Now, keep the base area the same but melt the snow. Example: A 10 cm depth of snow with density 300 kg m-3 has a snow water equivalent SWE(mm) = 10 cm (300 kg m-3)/100 = 30 mm.

Is 1 to 2 inches of rain a lot?

How much water is in a cubic inch of snow?

The ‘snow to ice ratio’ or Snow Ratio expresses how much volume of snow you get for a given volume of water. Typically a ratio of 10:1 (ten to one) means that every 10 inches of snowfall equals one inch of liquid water.

How much liquid is in a foot of snow?

While many snows that fall at temperatures close to 32oF and snows accompanied by strong winds do contain approximately one inch of water per ten inches of snowfall, the ratio is not generally accurate.
