 Saffir-Simpson Hurricane Scale - Wikipedia, the free encyclopedia
The Saffir-Simpson Hurricane Scale is a scale classifying most Western Hemisphere tropical cyclones that exceed the levels of "tropical depression" and "tropical storm" and thereby become hurricanes.
The Saffir-Simpson Hurricane Scale is used only to describe hurricanes forming in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line.
The initial scale was developed by Saffir while on commission from the United Nations to study low-cost housing in hurricane-prone areas.

 What is a Hurricane?
Not all hurricanes kill, the severity of a hurricane is rated by the Saffir-Simpson Hurricane Scale.
Hurricane - The storm is officially designated a hurricane when the winds reach a maximum sustained wind speed of 74 mph.
Since a hurricane is composed of thunderstorms, the rainfall often saturates the ground and causes massive flash flooding.

 Saffir/Simpson Hurricane Scale
A warning that hurricane conditions including sustained winds of 74 mph or greater associated with a hurricane are expected in a specified coastal area within 24 hours or less.
Hurricanes get names to help with tracking them (sometimes there may be more than one hurricane at a time and it can get confusing).
Sometimes names are "retired" if a hurricane has been really big and destructive.

 Saffir-Simpson Hurricane Scale
The Saffir-Simpson Hurricane Scale is a scale classifying hurricanes by the intensity of their sustained winds developed in 1969 by civil engineer Herbert Saffir and National Hurricane Center director Bob Simpson.
The initial scale was developed by Saffir on commission from the United Nations to study low-cost housing in hurricane-prone While performing the study Saffir realized there no simple scale for describing the likely of a hurricane.
Saffir gave the scale the NHC and Simpson added in the of storm surge and flooding.

The scale as devised, expresses what the extreme conditions can be expected from a hurricane of a certain type and a certain category.
It doesn't mean that everyone that a hurricane moves over, and the worst part of that hurricane, is going to receive that kind of damage or that kind of hazard.
I often felt that it was a little bit premature to put the scale out without perhaps improving it a little bit, and at least educating the people as to what it meant a little bit more.

 The Saffir/Simpson Hurricane Scale
In 1972, the Tropical Prediction Center (then known as the National Hurricane Center) adopted the Saffir/Simpson Hurricane Scale to relate hurricane intensity and damage potential.
Robert Simpson, former director of the National Hurricane Center, added additional reference to expected storm surge (the rise of a body of water above astronomical tide due to a tropical cyclone).
The scale had the advantage of relating ranges of sustained winds to effects on vegetation and structures.

The scale is named after Herbert Saffir, a consulting engineer in Coral Gables, Fla., and Robert Simpson, who was director of the National Hurricane Center from 1967 through 1973.
Saffir, an engineer and expert on wind damage who helped write the Dade County, Fla., building code, developed the first version of the scale in 1971 for a United Nations report on construction that could stand up to high winds.

The Saffir-Simpson scale is used to classify hurricanes in the United States.
Hurricanes usually form in the tropical zones north and south of the equator, where warm waters offer ample fuel for storm formation.
In recent years, Hurricane Andrew hit south of Miami as a Category 4 on August 24, 1992, but was upgraded to a Category 5 in 2002 after 10 years of research.

 THE DEADLIEST, COSTLIEST, AND MOST INTENSE UNITED STATES HURRICANES FROM 1900 TO 2000
In terms of central pressure (and probably winds), the strongest observed hurricane in the Atlantic basin was Gilbert in 1988 with a pressure of 888 millibars in the northwest Caribbean.
An early hurricane can be defined as occurring in the three months prior to the start of the season, and a late hurricane can be defined as occurring in the three months after the season.
With these criteria the earliest observed hurricane in the Atlantic was on March 7, 1908, while the latest observed hurricane was on December 31, 1954, the second "Alice" of that year which persisted as a hurricane until January 5, 1955.

 WashingtonPost.com: WeatherPost -- The Saffir-Simpson Scale
Since damage from hurricanes comes from a combination of factors, including wind, rain, floods, storm-surge height, and tornadoes, the Saffir-Simpson scale is used to gauge a hurricane based on all these factors.
The Saffir-Simpson hurricane intensity category system was developed in the 1970s to calculate the destructive force of hurricanes.

 Destruction Caused by Hurricanes: saffir-simpson scale and dangerous features
Once a hurricane develops, the Saffir-Simpson Scale is used to classify a hurricane's damage potential.
A number of theories exist about their origin, but in the case of Hurricane Andrew, severe damage was inflicted by small spin-up vortices that developed in regions of strong wind-shear found in the hurricane's eye wall.
The strong winds of the hurricane frequently hide the smaller tornado paths, making it difficult to attribute damage caused by one or the other.
