A tropical disturbance is an area of low pressure in the tropics that produces disorganized showers and thunderstorms. Tropical disturbances can produce gusty winds, but lack an organized circulation and center of rotation. A tropical storm is better organized, with a closed circulation and a well-defined center of circulation. By definition, a tropical storm must have sustained winds of 39 to 73 mph.
tropical disturbance, tropical depression, tropical storm, hurricane
The main difference between a hurricane and a tropical storm is their wind speeds. A hurricane has sustained winds of at least 74 mph, while a tropical storm has winds between 39-73 mph. Additionally, hurricanes are more organized and powerful than tropical storms.
A tropical disturbance begins as a cluster of thunderstorms over warm ocean waters. As it gains organization and intensity, it may develop into a tropical depression, tropical storm, and eventually a hurricane.
A hurricane will start as a Tropical Wave. It then becomes a Tropical Depression. A TD is given a number but not a name. Once the TD reaches 39 mile per hour winds its given a name and becomes a Tropical Storm. After reaching 74 mile per hour winds it becomes a hurricane.
Hurricane Sandy started out as a tropical disturbance over the Caribbean Sea. The disturbance was an area of low pressure that produced some showers and thunderstorms. Over the warm waters of the Caribbean the disturbance organized and strengthened first to a tropical depression, then to a tropical storm, then to a hurricane.

Before a storm becomes a hurricane it is called a tropical storm. Prior to that it is either a tropical depression or a tropical disturbance.
The difference is in intensity. A tropical depression is a tropical cyclone with winds under 39 mph. A tropical storm is a tropical cyclone with maximum sustained winds of 39 mph to 73 mph.
it started as a tropical disturbance at first, then it became a tropical depression, and a tropical storm, then a hurricane.

In order they are : tropical disturbance, tropical depression, tropical storm, sustained winds over 74 mph (hurricane/typhoon).
Tropical disturbance -> tropical depression -> tropical storm -> tropical cyclone (hurricane). *Hurricane is a local name, for tropical cyclones (official name) that appear in the Atlantic.
