The scale separates hurricanes into five different categories based on wind. The U.S. National Hurricane Center classifies hurricanes of Category 3 and above as major hurricanes. The Joint Typhoon Warning Center classifies typhoons of 150 mph (240 km/h) or greater (strong Category 4 and Category 5) as super typhoons.
A Category 4 hurricane has winds of 113 to 136 kn (130 to 157 mph; 209 to 252 km/h), while a Category 5 hurricane has winds of at least 137 kn (158 mph; 254 km/h). [1] [3] A post tropical cyclone is a system that has weakened, into a remnant low or has dissipated and formal advisories are usually discontinued at this stage. [1]
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 ...
Hurricanes in categories 3, 4 and 5 are considered major hurricanes due to their potential for significant loss of life and damage. Even Category 1 hurricanes can be dangerous and require preparation.
Once a tropical storm strengthens into a hurricane, it earns a category designation on the Saffir-Simpson Hurricane Wind Scale: 1 through 5.
What do the hurricane categories mean? The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage.
The 1935 Labor Day hurricane was the most intense hurricane to make landfall on the country, having struck the Florida Keys with a pressure of 892 mbar.It was one of only seven hurricanes to move ashore as a Category 5 hurricane on the Saffir–Simpson hurricane scale; the others were "Okeechobee" in 1928, Karen in 1962, Camille in 1969, Andrew in 1992, Michael in 2018, and Yutu in 2018, which ...
The Saffir–Simpson Hurricane Scale (SSHS) is a scale classifying most Western Hemisphere tropical cyclones that exceed the levels of "tropical depression" and "tropical storm" and thereby become hurricanes. The "categories" it divides hurricanes into are distinguished by the intensities of their respective 1-minute sustained wind speeds.
