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). [24] [25] At the tenth RA I tropical cyclone committee held during 1991, it was recommended that the intensity classifications be changed ahead of the 1993–94 tropical cyclone season.
To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m (33 ft) above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). [1] The highest classification in the scale, Category 5 , consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h).
Other areas label their tropical cyclones as "cyclones" or "typhoons", and use their own classification systems. Recently featured: 2004 Atlantic hurricane season – Hurricane Dennis – Hurricane Andrew – Browse

A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
The Non-tropical storms task force coordinates most of Wikipedia's coverage on extratropical cyclones, which tropical cyclones often transition into near the end of their lifespan. The Floods task force takes on the scope of flooding events all over the world, with rainfall from tropical cyclones a significant factor in many of them.
Post-tropical cyclones, such as remnant lows, no longer possess tropical quantities through either unfavorable conditions (e.g. increased wind shear) or land interaction. Pacific hurricane – a tropical cyclone that forms west of 100°W to the International Date Line in the Northern Hemisphere. The National Hurricane Center is responsible for ...
Category 1 is the lowest hurricane classification on the Saffir–Simpson scale. When a storm's wind speed is between 64 knots (74 mph; 119 km/h; 33 m/s) and 82 knots (95 mph; 153 km/h; 42 m/s), it is classified as a Category 1. [1] Since records began in 1851, 358 tropical cyclones have peaked at this intensity. [2]
