If visibility is reduced to 7 miles due to mist, light snow, and haze, what should be reported in column 9 (Present Weather)?

In this scenario, reporting the visibility conditions accurately is essential for providing a comprehensive weather observation. When visibility is reduced due to mist (BR), light snow (-SN), and haze (HZ), the convention is to report these weather phenomena in order of severity or influence on visibility.

The correct choice reflects the observation of light snow as the only significant present weather condition affecting visibility in this case. The light snow is indicated with a minus sign, representing that it is light in intensity. Even though mist and haze are present, they are not necessarily reported when a more significant condition like light snow is active. Therefore, the weather is simplified to just the light snow condition.

Other options combine mist and haze with light snow, but they either place them before or together in a way that does not follow standard reporting conventions. These combinations can lead to confusion or misinterpretation of the weather conditions impacting visibility.

Thus, the report solely capturing light snow, which might be impacting visibility most notably, is the most concise and accurate manner to convey the existing weather conditions.
