Which signal indicates a storm warning?

• A. Two Red Lights - Square red flag with black center
• B. Red White Red
• C. Two Red Pennants
• D. White over Red - Two Red Pennants

Answer: (A)

In maritime signaling, weather warnings use specific visual signals, and a storm warning is signaled by two red lights. Seeing two red lights tells the crew that a storm is imminent or conditions are deteriorating, so you immediately take protective actions: secure all loose gear, close watertight doors and hatches, reduce sail or adjust engine power as needed, and stay alert for further weather updates. The other patterns shown correspond to different warnings or notices and do not indicate a storm warning, so they’d not trigger the same urgent preparation.
