Tropical Depression: An area of low pressure, rotary circulation of clouds and winds of 38 mph or less (33. kts or less)
Tropical Storm: A storm characterized by counter-clockwise circulation of clouds and winds of 39 to 73 mph (34 to 64. kts)
Answer
Unless you live in the Southern Hemisphere where high pressure regions circulate in an anticlockwise fashion. In the Australian severe weather region a tropical cyclone must have 63 km/hrsustained winds and gusts to 90 km/hr. A severe tropical cyclone is 118 km/hr sustained 165 km/hr gusts.
What else can I help you with?
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 stages does a storm go through before it develops into a hurricane?
Tropical Depression and then Tropical Storm THEN Hurricane!
Was hurricane Andrew a tropical depression?
Yes. Hurricane Andrew was Tropical Depression Three for about a day before becoming Tropical Storm Andrew and then Hurricane Andrew 5 days later.
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.
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.

Which sequence storm stages is in the correct order?
tropical disturbance, tropical depression, tropical storm, hurricane
How did hurricane Andrew form?
he started as a tropical depression, then he became a tropical storm, then BAM! hurricane...!
How was Hurricane Andrew form?
it started as a tropical disturbance at first, then it became a tropical depression, and a tropical storm, then a hurricane.
What factors determine whether a storm is considered a tropical depression tropical storm or hurricane?
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.
Was hurricane Andrew a tropical depression?
Yes. Hurricane Andrew was Tropical Depression Three for about a day before becoming Tropical Storm Andrew and then Hurricane Andrew 5 days later.
Storm that develops from a tropical depression?
Hurricane, typhoon, etc.

Is a tropical storm first a tropical depression then a hurricane?
The progression of increasing strength is: Tropical depression (under 39 mph winds) Tropical storm (39-73 mph winds) Hurricane (winds 74 mph or higher)
How hurricane Andrew start?
Hurricane Andrew obviously started as a Tropical storm . every single hurricane starts as a tropical storm hurricanes can sometimes go from a tropical storm to A Up from hurricane to a tropical storm very quickly . but the wind speed to start a hurricane is 74 anything less is a tropical storm
