Which weather code would be used when there are no significant weather phenomena?

• A. Nil Significant Weather
• B. Ice Pellets
• C. Dust Devil
• D. Rain

Answer: (A)

When observers report weather, there’s a shorthand for indicating that nothing noteworthy is happening. This code communicates the absence of any significant weather phenomena, so no specific events need to be described. Nil Significant Weather is the best choice because it explicitly states that there are no notable weather conditions to report, letting operations know conditions are essentially clear of impactful phenomena. The other options describe actual weather events—ice pellets, a dust devil, or rain—that would be reported if they were occurring. So when nothing significant is observed, the nil code correctly signals that status.
