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]
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.
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. Knowing about each category can help predict what ...
The Saffir-Simpson Hurricane Wind Scale rates hurricanes from one to five. Category 1 hurricanes range from 74 to 95 mph and can bring very dangerous winds that can damage even sturdy houses. Category 1 is the weakest hurricane, and the storms strengthen up the scale from there. If a hurricane is Category 3 or higher, it is considered a major ...
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed.Here's how it breaks down. Hurricane Classifications: What do the categories ...
Cyclone Freddy. Category 4 is the second-highest classification on the Australian tropical cyclone intensity scale which is used to classify tropical cyclones, that have 10-minute sustained winds of at least wind speeds of 86–107 knots (159–198 km/h; 99–123 mph).
