What do dark clouds and shifting winds indicate?

• A. A calm sea and clear skies
• B. Rising temperatures
• C. Strong radio communications
• D. Provides warning of dangerous weather approaching

Answer: (D)

Dark clouds and shifting winds are classic signs that a storm is forming or moving in, signaling that dangerous weather is approaching. Dark clouds indicate increasing moisture and the potential for thunderstorms, while winds that change direction or speed point to changes in the air mass and a front moving through. Together, they warn you to take precautions: slow down, head toward shore or seek shelter, ensure everyone on board wears a life jacket, and monitor weather updates. The other options don’t fit because a calm sea and clear skies contradict the idea of an oncoming storm, rising temperatures alone don’t specifically indicate imminent dangerous weather, and strong radio communications isn’t tied to weather signs.
