Which quadrant of a hurricane is most dangerous?
right front quadrant
Hurricanes can be broken down into four quadrants and while all sides are dangerous, the most destructive is the right front quadrant. This is due to the forward motion contributing to the rotation of the storm. Don’t get me wrong, all sides of a hurricane can be strong but the right side takes the title of strongest.

What is the Centre of cyclone called?
In the centre of this system there usually is a cloudless, calm area called “The Eye”, with no rain and very light winds. The cyclone is now being sustained by a steady flow of warm, moist air being sucked in from the warm waters it is moving over.
What causes a semi circle?
The side of a tropical cyclone to the right of the direction of movement of the storm in the Northern Hemisphere (to the left in the Southern Hemisphere), where the winds are stronger because the cyclone’s translation speed and rotational wind field are additive.
