How much snow do you have?
With snow on the way, here are some snowfall measuring tips.
How to Measure Snow
Snowfall is measured to the nearest tenth of an inch. (3.7” for example)
It is typically measured every 6 hours.
If melting is expected before the next measurement time, it is measured before the melting occurs.
During windy conditions, blowing and drifting of the snow will make it difficult to get an accurate measurement. In these situations, 10 to 20 measurements of the new snowfall are taken in representative areas and then averaged. Care is taken to avoid snow drifts and areas that have been scoured out.
The location of the measurement is important. It should be in an open area away from obstructions such as trees and buildings.
Typically, what is known as a “snowboard” is used to take the measurements. A “snowboard” is a white board about 24”X24”. It is placed out in the area determined to be the best location to measure the snow. The measurement is taken on the “snowboard”. The snow is then cleared off of the board and the board is placed on top of the freshly fallen snow.
Preferred reporting times are: 9 am, 3 pm, 8 pm, and a storm total when the snow ends.
