What might be included in the remarks section of a METAR?

The remarks section of a METAR is specifically designed to include additional weather details that may not be covered in the main report. This section can provide observations on a variety of elements, such as unusual weather phenomena, additional visibility conditions, or noteworthy atmospheric conditions that are relevant to pilots and air traffic controllers. Including this information is essential because it helps to paint a more complete picture of the weather conditions at the airport and can enhance safety in flight operations.

Visibility information, flight path changes, and wind shear reports are generally included in other parts of the METAR format or communicated separately through other means, rather than in the remarks section. Therefore, these do not fit the primary purpose and function of the remarks section as effectively as additional weather details do.
