General Navigation USCG Question #810 (Set 26)

Which change in the condition of the seas could indicate the formation of a tropical storm or hurricane several hundred miles from your location?

Official USCG Answer & Rule Citation

Correct Answer: Option B — A long swell from an unusual direction

A long-period ocean swell propagating from an unusual or distant direction is frequently the precursor to a distant tropical storm or hurricane. High winds generate long-wavelength swells that outrun the storm center, serving as a classic early warning indicator.
