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.
The lowest classification on the SSHWS is a Category 1 hurricane, which has winds of between 64 and 82 kn (74 and 94 mph; 119 and 152 km/h). [1] [3] Should the hurricane intensify further then it will be rated as a Category 2 hurricane, if it has winds of between 83 and 95 kn (96 and 109 mph; 154 and 176 km/h).
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.
Still, the National Hurricane Center uses categories – set by sustained wind speed – to estimate possible property damage from hurricanes. Here’s what’s expected in each: Category 1: 74-95 mph
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 Saffir–Simpson hurricane wind scale, assigns a numerical classification of hurricanes into five categories distinguished by the intensities of their sustained winds. The scale spans from Category 1 (winds of at least 74 miles per hour (119 km/h)) to Category 5 (exceeding 156 miles per hour (251 km/h)).
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 ...
