General Navigation USCG Question #988 (Set 31)

Where is the dangerous semicircle located on a hurricane in the Southern Hemisphere?

Official USCG Answer & Rule Citation

Correct Answer: Option A — To the left of the storm's track

In the Southern Hemisphere, the dangerous semicircle is located to the left of the storm's track. This is where the storm's forward motion and rotational winds reinforce each other, creating the highest wind speeds and the most significant sea states, necessitating avoidance maneuvers to stay in the navigable semicircle.
