A tropical depression is a weak tropical cyclone wind sustained winds of less than 39 miles per hour. As the depression is fueled by moisture from warm ocean water it gains strength and becomes more organized. When wind speeds reach 39 mph it becomes a tropical storm. When they reach 74 mph it becomes 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.
Yes. Hurricane Andrew was Tropical Depression Three for about a day before becoming Tropical Storm Andrew and then Hurricane Andrew 5 days later.
Tropical disturbance -> tropical depression -> tropical storm -> tropical cyclone (hurricane). *Hurricane is a local name, for tropical cyclones (official name) that appear in the Atlantic.
Tropical Depression and then Tropical Storm THEN Hurricane!
When the temperature of the water under a hurricane heats up it adds much more power to the wind velocity, this makes for a much stronger and fiercer storm.

it started as a tropical disturbance at first, then it became a tropical depression, and a tropical storm, then a hurricane.
he started as a tropical depression, then he became a tropical storm, then BAM! hurricane...!

Yes, hurricanes start out as tropical depressions.
Hurricane Katrina first developed as a tropical depression on August 23 2005.
Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005 as the result of an interaction of a tropical wave and the remains of Tropical Depression Ten

The progression of increasing strength is: Tropical depression (under 39 mph winds) Tropical storm (39-73 mph winds) Hurricane (winds 74 mph or higher)
