How fast does it have to be spinning to quality as a Hurricane?

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 does more damage a fast hurricane or a slow one?

Depends on what you mean by a fast or slow hurricane. In terms of forward speed, a slow-moving hurricane is generally more damaging, as areas in the path of the storm are hit by torrential rains for extended periods of time, resulting in very severe flooding. In terms of wind speed, hurricanes with faster winds are more destructive, though no hurricane has slow winds.


Why the situation at the eye of the storm is calmer than its surrounding?

In a hurricane the winds surrounding the eye are rotating so fast that they cannot move farther inward. A parcel of air that move closer to the center would get flung back out. so, instead of air moving in from the sides as it does outside the hurricane's eye, it gently sinks from above the storm.


What is in the middle of a hurricane?

In the center of a hurricane is the eye, which is a region of calm weather with clear skies and low wind speeds. The eye is surrounded by the eyewall, where the strongest winds and heaviest rainfall occur.

How fast does wind have to be before its a hurricane in km?

; Category One Hurricane: Winds 74-95 mph; Category Two Hurricane: Winds 96-110 mph; Category Three Hurricane: Winds 111-130 mph; Category Four Hurricane: Winds 131-155 mph; Category Five Hurricane: Winds greater than 155 mph


How fast does a tropical storm go?

Tropical storms typically move at speeds ranging from 10 to 20 miles per hour (16 to 32 kilometers per hour), but they can move faster or slower depending on various factors such as atmospheric conditions and the terrain they encounter.


What type of damage can a hurricane cause?

Any answer will depend on the strength, speed and location of the storm relative to a large body of water. A powerful, slow, rain producing storm will cause a great deal more damage in coastal areas as opposed to a weakened, fast moving, low rainfall producing storm that has moved inland.
