Storm signal is indicated by which description?

• A. Two Red Lights
• B. Two Red Pennants
• C. Red White Red = Two square red flags with black centers
• D. White over Red - Two Red Pennants

Answer: (C)

Storm signals are shown by a distinctive flag pattern: two square red flags with black centers. In the signaling book this is described as a Red White Red signal, meaning you hoist two red square flags each with a black center to warn of an approaching storm. This visual cue was used to alert other vessels and shore stations to take precautions. The other signal patterns correspond to different instructions or conditions, so they don’t indicate a storm in this coding system.
