Wind measuring has been standardized globally to reflect the winds at 10 metres (33 ft) above mean sea level, [nb 1] and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to ...
These areas (except the JTWC) use three-minute or ten-minute averaged winds to determine the maximum sustained wind speed, creating an important difference which frustrates direct comparison between maximum wind speeds of storms measured using the Saffir–Simpson hurricane wind scale (usually 14% more intense) and those measured using a ten ...
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.
This scale – officially known as the Saffir-Simpson Hurricane Wind Scale – is a rating based on maximum sustained wind speed, which ranges from 74 to 157 mph, or higher.
The ACE metric factors in the maximum sustained wind of each tropical cyclone throughout its lifetime. A calculation is done every six hours for each named storm that forms and remains active, and ...
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 ...
A tropical system in which the 10-minute maximum sustained winds are between 64–89 knots (74–102 mph; 119–165 km/h). [17] Tropical depression A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) is 33 kn (38 mph or 62 km/h) or less. [1] Tropical disturbance
As of the 2 p.m. ET Friday advisory from the NHC, the storm was located about 125 miles south-southeast of Louisville, Kentucky with maximum sustained winds near 35 mph.
