Which description best captures a SPECI report?

Which description best captures a SPECI report?

• A. It is unscheduled and includes all METAR data plus additional remarks.
• B. It is a routine forecast product.
• C. It is identical to METAR.
• D. It contains fewer data elements than METAR.

Answer: (A)

A SPECI is an unscheduled, special weather observation issued when there is a significant change in weather conditions that could affect aircraft operations, occurring between routine METARs. It uses the same METAR data elements as a routine observation and can include additional remarks to describe the notable change. That’s why the description stating it is unscheduled and includes METAR data plus additional remarks is the best fit. It isn’t a routine forecast, it isn’t identical to METAR, and it doesn’t have fewer data elements than METAR.
