The Saffir–Simpson hurricane wind scale (SSHWS) is a tropical cyclone intensity scale that classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds.
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]
Hurricane categories. Category 1: Winds 74-95 mph. Damage primarily to shrubbery, trees, poorly constructed items, and unanchored mobile homes. Category 2: Winds 96-110 mph. Some roof damage ...
First published in 1944, it was the culmination of over 11 years of work. The book contains 3,857 numbered entries and approximately 7,000 illustrations. [1] The entries include knot instructions, uses, and some histories, categorized by type or function. It remains one of the most important and comprehensive books on knots.
Once a tropical storm strengthens into a hurricane, it earns a category designation on the Saffir-Simpson Hurricane Wind Scale: 1 through 5. Here’s what the hurricane categories mean Skip to ...
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. This scale estimates potential property damage.
In 1972, the National Hurricane Center (NHC) began ranking hurricanes according to wind speed with the Saffir–Simpson scale. A Category 3 has maximum sustained winds between 96 knots (110 mph; 178 km/h; 49 m/s) and 112 knots (129 mph; 207 km/h; 58 m/s). The NHC considers these winds to be sustained for a one-minute period at 10 metres (32.8 ...
