While most people know that tropical cyclones can contain damaging winds, many do not realize that they also produce several other hazards such as: tropical cyclones are storm surge, flooding, and tornadoes.
Depending on the strength of the winds in the circulation, tropical cyclones are further divided into tropical depressions, tropical storms, and hurricanes. When tropical cyclones reach hurricane strength, they become classified by wind speed.
The main parts of a tropical cyclone are the rainbands, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern in the northern hemisphere (clockwise in the southern hemisphere), and out the top in the opposite direction.
