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.
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.
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.
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 hurricane. Category 3 hurricanes start with maximum sustained winds of 111 mph (180 kph). How serious is a Category 5 hurricane? Catastrophic. A Category 5 hurricane destroys houses, cuts power ...
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 ...
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 Wind Scale rates hurricanes on a scale from 1 to 5.
