An unscheduled observation, reported to the nearest minute, not meeting SPECI criteria. Also will only be taken when local leadership determines there is a requirement in support of local operations or OPSEC considerations.

• A. Aviation Selected Local Weather Report (LOCAL)
• B. Aviation Routine Weather Report (METAR)
• C. Aviation Selected Special Weather Report (SPECI)
• D. 3-hourly observations

Answer: (A)

The key idea is how weather reports are used to support local operations. Aviation Selected Local Weather Reports (LOCAL) are specifically issued on an as-needed basis when local leadership determines there is a requirement for operations or OPSEC considerations. They’re reported without following a fixed schedule and can be made at a high level of timeliness, such as to the nearest minute, as needed for local needs. In this scenario, the observation is unscheduled, to the nearest minute, does not meet SPECI criteria, and is requested only when local leadership identifies a need for local operations or OPSEC support. That aligns precisely with LOCAL.

METAR is a routinely scheduled hourly weather observation, not an on-demand local report. SPECI is an unscheduled report issued when significant weather changes meet specific criteria, which this description explicitly says do not apply. 3-hourly observations are also fixed-interval, not unscheduled.
