7 Inches of Snow Equals How Much Rain

An easy thing to remember other than the age old 10 inches of snowfall is equivalent to 1 inch of rain is that if it is a mixed precipitation event there will be more water content in the snow. A typical ratio for our area is 10 inches of snow per inch of water but when the snow is wet or mixes with freezing rain or sleet at times.

Ratio of 121 is commonly stated but it depends on how large the flakes were when they fell how much they have settled and especially if theyve blown around and rendered far rounder and denser or.

. Answer 1 of 2. 2 inches of rain equals how much snow. A good estimate would be 6-7 feet but of course its not that simple.

Rainfall of 004 equals how much snow. Measure by pouring the melted snow into the graduated rain tube and get a direct measure of the water content. It has been my understanding that it takes about 10 inches of snowfall to equal one inch of precipitation and if you will rain.

While many snows that fall at temperatures close to 32 o F and snows accompanied by strong winds do contain approximately one inch of water per ten inches of snowfall the ratio is not generally accurate. So 49 inches of snow would be equal to about 5 inches of rain. This varies depending on the type of snow but to make 1 inch of water rain you need 10 inches of average snow 4 to 5 inches.

Ten inches of fresh snow can contain as little as 010 inches of water. Warmer air can hold more moisture so its not as if all that rain could have been snow if. The fluffiness of the snow can vary how deep it.

A foot of snow equals an inch of rain 83 water content. I have heard others say that it takes up to 20 inches so that could mean it could take from 20 to 40 inches. 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.

Lets say we wanted to. Or calculate the water content with the depth of the snow in the tube and the ambient temperature. 7 rows snow depth inches rainfall inches rain-to-snow ratio.

In the past the rule of thumb was relatively simple -- an inch of rainfall translated to about 10 inches of snow. We had 175 inches of liquid equivalent yet ended up with 232 inches of snow not 175 inches of accumulation. Or weigh the snow.

So that 6 inches that just fell if it were a pretty typical snowfall would have been about a half-inch of rain. The water content of snow is more variable than most people realize. Better and more recent research has now adjusted that rule of thumb to about a foot of snow to 1 inch of rain.

The calculated data is based on information from the National Weather Service that indicates the average snowfall is in a ratio of 10 inches of snow to 1 inch of equivalent rainfall. During that storm the snow ratio was closer to 15 inches of snow to one inch of rain. A conversion chart that converts snowfall depths and amounts to the water equivalent.

No need to melt the snow.
