A tropical cyclone is tracking to the North along the coast of Japan. To which direction is the dangerous semi-circle located?

Correct Answer: Option C — East

In the Northern Hemisphere, the dangerous semi-circle of a tropical cyclone is the right-hand side of the storm's path. For a cyclone tracking North, the dangerous semi-circle lies to the East. Mariners must avoid this quadrant to prevent being pushed into the storm's center by the prevailing wind and current.
