Quizplus · Accepted Answer

A tropical storm is the stage just before a hurricane is fully developed. This is when maximum sustained winds reach 39-73 mph. Prior to this stage, the storm is considered a tropical depression (winds less than 39 mph) and a tropical disturbance (an area of organized convection with no closed circulation). After the tropical storm stage, the storm is classified as a hurricane (winds above 74 mph). The term "tropical cyclone" is often used as a generic term for any of these stages.
