The Saffir–Simpson hurricane wind scale (SSHWS) classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds.

New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers.In conjunction with the National Hurricane Center, the national meteorological and hy...
China
A two-stage warning system was long-established in China for tropical cyclones of tropical storm intensity of above.Nowadays, the use of this system is restricted to coastal waters only. Thus, warnings may be discontinued even if a cyclone is maintaining tropical storm intensity inland. Color-coded alerts (below) may be in effect independently of any two-stage warnings. Later, China Meteorological Administration standardized the system for national use.This set is part of a larger warning sys...
Hong Kong and Macau
The Pearl River Deltauses a variety of warning systems to inform the public regarding the risks of tropical cyclones to the area. The Hong Kong Observatory issues typhoon signals to indicate the existence and effects of a tropical cyclone on Hong Kong. The first numeric warning system was used in 1917. The Macao Meteorological and Geophysical Bureau in Macauuses a similar system. In Hong Kong the typhoon signal system consists of 8 signals in 5 levels numbered non-consecutively for historical...
Japan
The Japan Meteorological Agency (JMA) is the government agency responsible for gathering and providing results for the public in Japan, that are obtained from data based on daily scientific observation and research into natural phenomena in the fields of meteorology, hydrology, seismology and volcanology, among other related scientific fields. Its headquarters is located in Tokyo. JMA is also designated one of the Regional Specialized Meteorological Centers (RSMC) of the World Meteorological...
The Australian Bureau of Meteorology will issue a cyclone watch for a specified part of Australia, when a tropical cyclone is expected to cause gale-force winds in excess of 62 km/h (40 mph) within 24–48 hours and subsequently make landfall.A cyclone warning is subsequently issued for a specified part of Australia when a tropical cyclone, is expect...
The Indian Meteorological Department (IMD/RSMC New Delhi) is responsible for tracking tropical cyclones within the North Indian Ocean.Météo-France in Réunion(MFR/RSMC La Reunion) is responsible for the issuing advisories and tracking of tropical cyclones in the southwest part of the basin, however, the naming of systems is deferred to the Mauritius...
HURCON/TCCOR
The United States Department of Defenseuses a multi-stage system called the Hurricane Condition (HURCON) in the North Atlantic and the Northeast Pacific and the Tropical Cyclone Condition of Readiness (TCCOR) in the western Pacific to prepare bases and evacuate assets and personnel in advance of adverse weather associated with tropical cyclones. The alerts are recommended by weather facilities either on base or by central sites like the National Hurricane Center or the Joint Typhoon Warning C...
Tropical cyclones are ranked according to their maximum winds using several scales. These scales are provided by several bodies, including the World Meteorological Organization, the National Hurricane Center, and the Bureau of Meteorology.
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed. This scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding, and tornadoes.
The Saffir-Simpson Hurricane Wind Scale is a 1-5 rating based on the hurricane's present intensity. This scale only addresses the wind speed and does not consider the potential for other hurricane-related impacts, such as storm surge, rainfall-induced floods, and tornadoes.
