Hurricanes begin as tropical disturbances in warm ocean waters with surface temperatures of at least 80 degrees Fahrenheit. These low pressure systems are fed by energy from the warm seas. If a storm achieves wind speeds of 38 miles an hour, it becomes known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles an hour. When a storm's sustained wind speeds reach 74 miles an hour it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.
The Saffir-Simpson scale was developed in 1971 and until 2008 and Hurricane Ike, used to be a measure of both wind speed and storm surge. Hurricane Ike measured at a category 2 on the Saffir-Simpson scale, but it's storm surge at landfall was at a level to match a category 4 storm. It was felt that many may have underestimated the need to evacuate based on the storms category 2 rating so for the 2009 hurricane season the scale was revamped to measure only wind speed. The storm surge will now be estimated by location.
The Saffir-Simpson Wind Scale:
Category One Hurricane (Sustained winds 74-95 mph)
Category Two Hurricane (Sustained winds 96-110 mph)
Category Three Hurricane (Sustained winds 111-130 mph)
Category Four Hurricane (Sustained winds 131-155 mph)
Category Five Hurricane (Sustained winds greater than 155 mph)
What else can I help you with?
What part of a hurricane spins the fastest?
The fastest spinning part of a hurricane is the eye wall.
What is the lowest recorded speed of a hurricane spinning?
The minimum wind speed for a hurricane is 74 miles per hour. Below that the storm is not considered to be a hurricane.
If a hurricane carries 100 mph winds why does it only travel 25-35 mph?
The very vast winds in a hurricane are spinning around the center. The speed at which the hurricane moves depends on the broader winds that push it around. Think about it like a top. A top can spin very fast while only moving slowly across the table.
What is the name of a storm in which rapidly spinning air becaomes very dangerous?
A cyclone or hurricane.
How fast were the winds for hurricane Charley?
Hurricane Charley peaked as a strong category 4 hurricane with sustained winds of 150 mph.

How fast can the wind get in the jungle?
As fast as a hurricane with no doubt
What is a large spinning storm that has winds over 117 kilometers (73 miles) per hour?
A violent rotating windstorm spawned by a thunderstorm is a tornado.

How fast do the wind have to be a hurricane?

What company makes a quality hurricane shutter?
A quality hurricane shutter can be purchased from many retailers. I would go with Shutter Shack.com.
How fast are the winds of a hurricane?
The winds of a hurricane must be at least 119 km/h.
How fast can a Hawker Hurricane plane go?
The Hurricane could fly at about 340 mph.
Why is it clear and calm in a tornado?
It is believed that some tornadoes have a calm, clear center similar to the eye of a hurricane. This is caused by the winds spinning so fast that they cannot reach the center. Aside from that it is neither calm nor clear in a tornado.
How fast were the winds for hurricane Charley?
Hurricane Charley peaked as a strong category 4 hurricane with sustained winds of 150 mph.
