[1][3] This scale is only officially used in American Samoa, however, various agencies including NASA also use it to compare tropical cyclones.
[1] A Category 3 tropical cyclone is expected to cause catastrophic devastation, if it significantly impacts land at or near its peak intensity.
[2][3] In addition to the systems listed above, Severe Tropical Cyclone's Bebe, Gyan, Abigail, Nisha-Orama, Oscar, Tomasi, Veena, Uma, Bola, Wasa-Arthur, Joni, Sarah, Beti, Kim, Paula, Waka, Eseta, Ivy, Daman, Funa, Freda and Hola were all considered to have 1-minute sustained wind speeds equivalent to a Category 3 hurricane on the SSHWS by the JTWC.
Operationally, the BoM considered Severe Tropical Cyclone Dovi to have peaked with 10-minute sustained wind-speeds of 155 km/h (100 mph) which made it a Category 3 severe tropical cyclone.
[116] However, New Zealand's MetService estimated that Dovi had peaked with 10-minute sustained windspeeds of 175 km/h (110 mph) which made it a Category 4 severe tropical cyclone.
