What does "4/ group" indicate in a weather report?

The phrase "4/ group" in a weather report indicates the measurement of snowfall on the ground expressed in whole inches. It signifies that there are four inches of snow accumulated at the reporting station. This measurement helps meteorologists and weather observers assess current conditions, particularly in winter weather scenarios, providing critical information about snowfall accumulation for forecasting and public safety.

In this case, measuring snow in whole inches gives a clear and simple way to communicate the depth of snow that remains on the ground, rather than indicating recent snowfall, rainfall, or other water-related metrics, which are covered by different abbreviations or phrases in weather reporting. This format assists in tracking long-term snow conditions, which is essential for various applications, including transportation and outdoor activities.
