## Saffir–Simpson scale |

The **Saffir–Simpson hurricane wind scale** (**SSHWS**), formerly the **Saffir–Simpson hurricane scale** (**SSHS**), classifies

Category | Wind speeds (for 1-minute | |||
---|---|---|---|---|

Five | ≥ 70 m/s | ≥ 137 kn | ≥ 157 mph | ≥ 252 km/h |

Four | 58–70 m/s | 113–136 kn | 130–156 mph | 209–251 km/h |

Three | 50–58 m/s | 96–112 kn | 111–129 mph | 178–208 km/h |

Two | 43–49 m/s | 83–95 kn | 96–110 mph | 154–177 km/h |

One | 33–42 m/s | 64–82 kn | 74–95 mph | 119–153 km/h |

Tropical storm | 18–32 m/s | 34–63 kn | 39–73 mph | 63–118 km/h |
---|---|---|---|---|

Tropical depression | ≤ 17 m/s | ≤ 33 kn | ≤ 38 mph | ≤ 62 km/h |

To be classified as a hurricane, a

Officially, the Saffir–Simpson hurricane wind scale is based on the highest average wind over a __ one-minute__ time span and used

Other areas use *three-minute* or *ten-minute* averaged winds to determine the maximum sustained winds which is an important difference and makes a direct comparison of other storm scales with the Saffir–Simpson scale difficult.

There is some criticism of the SSHWS for not taking rain,

The scale was developed in 1971 by ^{[1]} The scale was introduced to the general public in 1973,^{[2]} and saw widespread use after ^{[3]}

The initial scale was developed by Herbert Saffir, a ^{[4]} While performing the study, Saffir realized there was no simple scale for describing the likely effects of a hurricane. Mirroring the utility of the

In 2009, the NHC made moves to eliminate pressure and storm surge ranges from the categories, transforming it into a pure wind scale, called the Saffir–Simpson Hurricane Wind Scale (Experimental) [SSHWS].^{[5]} The new scale became operational on May 15, 2010.^{[6]} The scale excludes flood ranges, storm surge estimations, rainfall, and location, which means a Category 2 hurricane which hits a major city will likely do far more cumulative damage than a Category 5 hurricane that hits a rural area.^{[7]} The agency cited various hurricanes as reasons for removing the "scientifically inaccurate" information, including ^{[8]} Since removed from the Saffir–Simpson hurricane wind scale, storm surge predicting and modeling is now handled with the use of computer numerical models such as

In 2012, the NHC expanded the windspeed range for Category 4 by 1 mph in both directions, to 130–156 mph, with corresponding changes in the other units (113–136 kn, 209–251 km/h), instead of 131–155 mph (114–135 kn, 210–249 km/h). The NHC and the ^{[5]} The new scale became operational on May 15, 2012.^{[9]}
