Saffir-Simpson Hurricane Scale – a scale widely used by the National Hurricane Center, Central Pacific Hurricane Center, and the Joint Typhoon Warning Center to determine a storm's strength using maximum sustained winds. Accumulated cyclone energy – a metric used by several agencies to measure the longetivity of a tropical cyclone.
In the United States of America, winds of force 6 or 7 result in the issuance of a small craft advisory, with force 8 or 9 winds bringing about a gale warning, force 10 or 11 a storm warning ("a tropical storm warning" being issued instead of the latter two if the winds relate to a tropical cyclone), and force 12 a hurricane-force wind warning ...
An announcement that hurricane conditions (sustained winds of 74 mph or higher) are possible within the specified coastal area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.

Hurricane categories. Category 1: Winds 74-95 mph. Damage primarily to shrubbery, ... 4 and 5 are considered major hurricanes due to their potential for significant loss of life and damage.
The categories are defined by wind speed, with a storm of Category 3, 4, or 5 considered a major hurricane. And damage is exponential as wind speed increases, meaning a strong Category 3 storm ...
Each year on average, around 80 to 90 named tropical cyclones form around the world, of which over half develop hurricane-force winds of 65 kn (120 km/h; 75 mph) or more. [1] Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each ...
A hurricane's category describes potential wind damage but does not describe other deadly hurricane hazards such as storm surge. ... 'Category 5' was considered the worst hurricane. There's ...
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]
