Fog/mist is responsible for lowering the visibility to 5/8 mile. Light rain is also occurring. The present weather would be coded:

The correct coding for weather conditions is essential for accurately conveying information about visibility and weather phenomena. In this scenario, you have fog/mist causing visibility to drop to 5/8 mile and light rain also occurring.

The coding for weather phenomena uses specific abbreviations. "FG" stands for fog, while "BR" is used for mist (or visibility-reducing phenomena that aren't as dense as fog). The "-RA" denotes light rain.

When both fog/mist and light rain are present, the phenomenon that is more significant in impacting visibility is usually placed first in the coding. Since mist (represented as "BR") is causing the reduced visibility, it takes precedence, especially when visibility is critically low due to this condition. Therefore, "BR" is coded first.

Following this, we need to indicate the light rain, which is coded as "-RA". The correct interpretation here prioritizes the mist condition while still recognizing the presence of light rain as a contributing factor to the weather conditions.

Option C, "-RA BR", correctly indicates that there is light rain occurring along with mist, thus capturing both elements of the current weather scenario accurately for weather reporting purposes. This sequencing aids in clarity and proper dissemination of weather information to pilots and meteor
