The dangerous semicircle is the upper-right corner, with the arrow marking the direction of motion of a Northern Hemisphere storm. Note that typhoons, etc. are asymmetrical, and semicircle is a convenient misnomer. Mariners have a way to safely navigate around tropical cyclones.

Do you know the difference between a watch and a warning? What's an invest? Here's a guide.
A hurricane's category describes potential wind damage but does not describe other deadly hurricane hazards such as storm surge. 'Uninhabitable for weeks or months': Why Helene's hurricane ...
Hurricane Milton grew from a tropical storm to a Category 5 hurricane in just over 24 hours. That rapid intensification is part of a trend fueled by climate change.
Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.
There, the observed wind speed of the storm is the sum of the speed of wind in the storm circulation plus the velocity of the storm's forward movement. Buys Ballot's law calls this the "Dangerous Quadrant". Likewise, in the left front quadrant of the storm the observed wind is the difference between the storm's wind velocity and its forward ...
