 Tropical cyclone - Wikipedia, the free encyclopedia
In meteorology, a tropical cyclone (also referred to as a tropical depression, tropical storm, typhoon, or hurricane depending on strength and geographical context) is a type of low pressure system which generally forms in the tropics.
Condensation as a driving force is what primarily distinguishes tropical cyclones from other meteorological phenomena, and because this is strongest in a tropical climate, this defines the initial domain of the tropical cyclone.
Tropical cyclones far from land are tracked by weather satellites using visible light and infrared bands.

Cape Verde-type hurricanes are those Atlantic basin tropical cyclones that develop into tropical storms fairly close (less then 1000 kilometres) to the Cape Verde Islands, off the west coast of Africa, and then become hurricanes before reaching the Caribbean.

NHC forecast tracks of the center can be in error; the average track forecast errors in recent years was used to construct the areas of uncertainty for the first 3 days (solid white area) and for days 4 and 5 (white stippled area).
The area experiencing hurricane force (one-minute average wind speeds of at least 74 mph) and tropical storm force (one-minute average wind speeds of 39-73 mph) winds can extend well beyond the white areas shown enclosing the most likely track area of the center.
The distribution of hurricane and tropical storm force winds in this tropical cyclone can be seen in the Cumulative Wind Distribution graphic displayed below.

 Stages of Development: from tropical depression to hurricane
Once a disturbance has become a tropical depression, the amount of time it takes to achieve the next stage, tropical storm, can take as little as half a day to as much as a couple of days.
The same may occur for the amount of time a tropical storm needs to intensify into a hurricane.

 Tropical Depression:
A tropical depression is designated when the first appearance of a lowered pressure and organized circulation in the center of the thunderstorm complex occurs.
When viewed from a satellite, tropical depressions appear to have little organization.
Instead of a round appearance similar to hurricanes, tropical depressions look like individual thunderstorms that are grouped together.
