Hurricane Structure

The Main structure of a Hurricane consist of the following:
  • Spiral rainbands which are made up of lines of thunderstorms that contain heavy precipitation.
  • The Eyewall which is a thick wall of clouds surrounding the eye. Here is where the strongest winds exist.
  • The Eye which is an area at the center of the storm where winds are calm and the sky is almost cloud free.
