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 ...
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

The extent of spiral banding and difference in temperature between the eye and eyewall is used within the technique to assign a maximum sustained wind and pressure. [6] Central pressure values for their centers of low pressure are approximate. The tracking of individual clouds on minutely satellite imagery could be used in the future in ...
Tropical cyclone intensity is based on wind speeds and pressure. Relationships between winds and pressure are often used in determining the intensity of a storm. [55] Tropical cyclone scales, such as the Saffir-Simpson hurricane wind scale and Australia's scale (Bureau of Meteorology), only use wind speed for determining the category of a storm.
On Aug. 22, 1992, Hurricane Andrew pummeled southern Florida as a monster Category 5 storm with sustained wind speeds as high as 165 mph and gusts as high as 174 mph. Homes were reduced to piles ...
These eye-like features are most normally found in intensifying tropical storms and hurricanes of Category 1 strength on the Saffir-Simpson scale. For example, an eye-like feature was found in Hurricane Beta when the storm had maximum wind speeds of only 80 km/h (50 mph), well below hurricane force. [26]
The hurricane center's forecast for Helene's rapid transition from unnamed storm to Cat 3 hurricane may be the fastest ever. ... the limiting factor for peak wind speeds and lowest pressure is how ...
Category 1 storms on the Saffir-Simpson Hurricane Wind Scale have speeds beginning at 74 mph. One Kentucky county recorded a gust higher.
