Category 4 is the second-highest hurricane classification category on the Saffir–Simpson Hurricane Scale, and storms that are of this intensity maintain maximum sustained winds of 113–136 knots (130–156 mph, 209–251 km/h). Based on the Atlantic hurricane database, 144 hurricanes have attained Category 4 hurricane status since 1851, the ...
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 ...
If it does hit at Cat 4 power, the storm by definition would be be expected to leave a trail of "catastrophic" damage. The National Hurricane Center says Category 4 storms threaten well-built ...
The Saffir-Simpson Hurricane Wind Scale rates hurricanes on a scale from 1 to 5.
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 ]
So an intensity of 115 kn is rated Category 4, but the conversion to miles per hour (132.3 mph) would round down to 130 mph, making it appear to be a Category 3 storm. Likewise, an intensity of 135 kn (~155 mph, and thus Category 4) is 250.02 km/h, which, according to the definition used before the change would be Category 5. [11]
[1] [2] A named storm can also be classified as a Category 4 tropical cyclone if it is estimated to have 1-minute mean maximum sustained wind speeds of between 113–136 knots (209–252 km/h; 130–157 mph) on the Saffir-Simpson hurricane wind scale.
Hurricane Milton is currently a Category 4 storm and follows Hurricane Helene and long history of other storms that have caused life-altering effects for the people that are in its path.
