In 2024 another proposal to add "Category 6" was made, with a minimum wind speed of 192 mph (309 km/h), with risk factors such as the effects of climate change and warming ocean temperatures part of that research. [30] In the NHC area of responsibility, only Patricia had winds greater than 190 mph (85 m/s; 165 kn; 305 km/h).
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

A Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the Atlantic Ocean to the north of the equator. They are among the strongest tropical cyclones that can form on Earth, having 1-minute sustained wind speeds of at least 137 knots (254 km/h ; 158 mph ; 70 m ...
In 1973, the National Hurricane Center introduced the Saffir-Simpson scale, a five-category rating system that classified hurricanes by wind intensity.. At the bottom of the scale was Category 1 ...
On Aug. 22, 1992, Hurricane Andrew pummeled southern Florida as a monster Category 5 storm with sustained wind speeds as high as 165 mph and gusts as high as 174 mph. Homes were reduced to piles ...
Category 1: Wind Speed: 74-95 mph (119-153 km/h) Damage: Minimal. Some damage to trees, shrubs, and unanchored mobile homes. Minor damage to buildings. Category 2: Wind Speed: 96-110 mph (154-177 ...
Extreme wind warning EWW – An extreme wind event producing sustained surface winds of 100 knots (120 mph; 190 km/h) or greater, associated with the eyewall of a major hurricane (Category 3 or higher on the Saffir-Simpson Scale), non-convective winds, downslope winds or a derecho is occurring or expected to occur in the specified coastal or ...
The new AccuWeather RealImpact Scale for Hurricanes will work to solve this problem by using a multi-dimensional approach to determine and communicate the real impact of storms rather than just ...
