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 ...
Hurricane Condition (HURCON) is an alert scale used by the United States Armed Forces in the North Atlantic and the North Pacific to indicate the state of emergency or preparedness for an approaching hurricane. This designation is especially important to installations in the southern Atlantic region, as it is most affected by hurricanes.
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.
An announcement that hurricane conditions (sustained winds of 74 mph or higher) are expected somewhere within the specified coastal area. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the hurricane warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.
