Wind speeds in knots are then converted to other units and rounded to the nearest 5 mph or 5 km/h. [2] The Saffir–Simpson hurricane wind scale is used officially only to describe hurricanes that form in the Atlantic Ocean and northern Pacific Ocean east of the International Date Line.
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 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.
Category 3: Winds 111-130 mph. Extensive damage to roofing, siding, and windows. Major damage to mobile homes. Major damage to mobile homes. Inland flooding possible.
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed.Here's how it breaks down.
Warm water temperatures, which was seen during Hurricane Wilma when its winds rapidly strengthened to 185 mph (298 km/h) in a 24-hour period due to the presence of abnormally warm water temperatures. Size and speed of the storm, which results in damage along a wide area as seen in Hurricane Isabel and Great New England Hurricane of 1938. [3] [4]
Editor's note: Read USA TODAY's coverage of Helene's landfall and impacts for Friday, Sept. 27.. As monster storms like Helene approach the U.S., meteorologists use five categories to help signal ...
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 hurricane. Category 3 hurricanes start with maximum sustained winds of 111 ...
