The determining factor is the sustained wind speed. If the tropical system has sustained winds of less than 39 miles per hour, then it is a tropical depression. If sustained winds are in the range of 39 to 73 mph, then it is a tropical storm. If sustained winds are 74 mph or faster, then it is a hurricane.

What is a typhoon depression?
A typhoon and a tropical depression are different intensity levels of tropical cyclone. A tropical depression is organized enough to be considered a tropical cyclone, but has sustained winds of less than 39 mph. If a depression gets stronger it is considered a tropical storm. A typhoon is equivalent to a hurricane, with sustained winds of 74 mph or higher. Most typhoons stat out as tropical depressions.
What factor determines when a tropical storm becomes a hurricane?
When the wind speed is greater than 74 miles per hour, it is considered a hurricane, category one.when the wind exceed 119 km/h the storms is classified as hurricane.

Why is a hurricane called a tropical depression?
A tropical depression is a tropical cyclone with winds under 39 mph. When winds reach or exceed that limit it is called a tropical storm and is given a name. Tropical depression 9 denotes the 9th tropical cyclone of that year in a particular ocean basin.

hurricane
What determines when a storm or tropical depression is given hurricane status?

Hurricane formation from weakest to strongest?
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.
What are the types of storms that form before a hurricane forms?
Tropical disturbance -> tropical depression -> tropical storm -> tropical cyclone (hurricane). *Hurricane is a local name, for tropical cyclones (official name) that appear in the Atlantic.

When is a hurricane considered a tropical storm and what are all the different types a storm a hurricane can turn into?
A hurricane cannot be a tropical storm as by definition a tropical storm is weaker than a hurricane. A tropical storm is a tropical cyclone with winds of 39-73 mph. Only when winds reach 74 mph or greater is the storm considered a hurricane. A hurricane can weaken into a tropical storm and from there into a tropical depression (winds under 39 mph). A tropical storm or depression may also degenerate into a remnant low, which is too disorganized to be considered a tropical cyclone. A tropical cyclone (hurricane, tropical storm, or tropical depression) may also become an extratropical cyclone after moving over land or cold water. Around the world hurricanes have different names. In the northwest Pacific ocean they are called typhoons, In the Indian ocean they are called intense tropical cyclones, and in the south Pacific they are simply called cyclones. However, these are just different names for essentially the same kind of storm.
