The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a certain distance from the center, known as the radius of maximum wind, or RMW.
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).
The most intense tropical cyclone in the North Indian Ocean by both sustained winds and central pressure was the 1999 Odisha cyclone, with 3-minute sustained winds of 260 km/h (160 mph) and a minimum pressure of 912 hPa (26.93 inHg). Storms with an intensity of 950 hPa (28.05 inHg) or less are listed.
As of Wednesday morning, Milton had maximum sustained winds of about 155 mph (249 kph), according to the hurricane center. Hurricane-force winds extend outward up to 30 miles (45 km) from its ...
At the bottom of the scale was Category 1, for storms with sustained winds of 74 to 95 mph. At the top was Category 5, for disasters with winds of 157 mph or more.
Maximum sustained winds: 145 mph. Movement: east-northeast at 12 mph. Milton is expected to produce damaging hurricane-force winds and a life-threatening storm surge with destructive waves across ...
The scale used by Regional Specialized Meteorological Centre (RSMC) New Delhi applies a 3-minute averaging period, and the Australian scale is based on both 3-second wind gusts and maximum sustained winds averaged over a 10-minute interval. These differences make direct comparisons between basins difficult.
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 ...
