It is calculated by summing the square of tropical cyclones' maximum sustained winds, as recorded every six hours, but only for windspeeds of at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph); [4] the resulting figure is divided by 10,000 to place it on a more manageable scale. [2]
A minor change to the scale was made ahead of the 2012 hurricane season, with the wind speeds for Categories 3–5 tweaked to eliminate the rounding errors that had occurred during previous seasons, when a hurricane had wind speeds of 115 kn (130 mph; 215 km/h). [7]

Fed by climate change, hurricanes have outpaced the tool meteorologists use to convey their strength, and the National Hurricane Center should add a Category 6 to the Saffir-Simpson scale to ...
Tropical Storm Allison, which did not receive a hurricane numerical designation on the Saffir-Simpson scale, made landfall in Texas in 2001, causing catastrophic flooding and the deaths of more ...
This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m (33 ft) above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). [1]
TALLAHASSEE, Fla. – Hurricane Helene is now predicted to reach Florida as a Category 4 hurricane, part of a frightening forecast of 130-mph winds and high storm surge that brings a dire scenario ...
