If a tropical cyclone intensify further and reaches wind speeds of 90 knots (170 km/h; 100 mph), it will be classified as an intense tropical cyclone. A very intense tropical cyclone is the highest category on the South-West Indian Ocean Tropical Cyclone scale, and has winds of over 115 knots (213 km/h; 132 mph).
Of the 42 hurricanes currently considered to have attained Category 5 status in the Atlantic, 19 had wind speeds at 175 mph (78 m/s; 152 kn; 282 km/h) or greater. Only 9 had wind speeds at 180 mph (80.5 m/s; 156 kn; 290 km/h) or greater (the 1935 Labor Day hurricane, Allen, Gilbert, Mitch, Rita, Wilma, Irma, Dorian, and Milton).
The most intense tropical cyclone in the South-West Indian Ocean was Cyclone Gafilo. By 10-minute sustained wind speed, the strongest tropical cyclone in the South-West Indian Ocean was Cyclone Fantala. Storms with an intensity of 920 hPa (27.17 inHg) or less are listed. Storm information was less reliably documented and recorded before 1985. [6]
Cyclone Judy. Category 4 the second-highest classification on the Australian tropical cyclone intensity scale which is used to classify tropical cyclones, that have 10-minute sustained winds of at least wind speeds of 86–107 knots (159–198 km/h; 99–123 mph).
Within the basin a very severe cyclonic storm is defined as a tropical cyclone that has 3-minute mean maximum sustained wind speeds of between 64–89 knots (119–165 km/h; 74–102 mph). The category was introduced alongside the Super Cyclonic Storm category during 1999 in order to replace the previously used Severe Cyclonic Storm with Core ...
The highest is Category 5, which means a storm that has a sustained wind speed of 157 mph or higher. ... The cyclone was initially measured as a Category 4 storm, ...
When the term “tropical cyclone ... Hurricanes are called when the storm’s sustained wind speeds clock 74 mph or greater, with 111 mph winds being classified as a major hurricane — Category ...
For the intensity scale, PAGASA lowered the threshold wind speed for classifying super typhoons from 220 km/h to 185 km/h and defined a super typhoon as an extreme tropical cyclone with 10-minute maximum sustained winds reaching 185 km/h or greater (the range of wind speed for typhoon category is consequently adjusted to 118–184 km/h).
