Which weather phenomena are reported in the remarks section of METARs?

The remarks section of a METAR report is used to provide additional information about specific weather phenomena that may not be covered in the routine part of the report. This section can include a variety of significant weather events occurring at the reporting station.

Funnel clouds, lightning, precipitation, and thunderstorms are all pertinent data that can be included in the remarks section. Funnel clouds may indicate potential tornado activity, while lightning is crucial for assessing storm severity and safety. Precipitation can be detailed regarding type and intensity, giving pilots and meteorologists valuable insights into current conditions. Thunderstorms also have implications for flight safety and operations, making their reporting essential.

The breadth of this information allows those interpreting the METAR to understand more fully the conditions at the airport, ensuring better-informed decision-making for flight operations. Hence, choosing the comprehensive option that includes all these phenomena accurately reflects the purpose of the remarks section within METAR reports.
