The Saffir–Simpson hurricane wind scale ... the NHC extended the wind speed range for Category 4 by 1 mph in both directions, to 130–156 mph, with corresponding ...
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 following table lists the most intense Atlantic hurricanes in terms of their lowest barometric pressure. In terms of wind speed, Allen from 1980 was the strongest Atlantic tropical cyclone on record, with maximum sustained winds of 190 mph
The most intense storm by lowest pressure and peak 10-minute sustained winds was Typhoon Tip, which was also the most intense tropical cyclone ever recorded in terms of minimum central pressure. Storms with a minimum pressure of 899 hPa (26.55 inHg) or less are listed. Storm information was less reliably documented and recorded before 1950. [6]
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 ...
Hurricane Center tracking area of low pressure. Here’s how it could affect Myrtle Beach, SC this weekend ... bringing 1 to 2 inches of rain and wind gusts between 25 to 30 miles per hour, said ...
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.
Category 1 storms on the Saffir-Simpson Hurricane Wind Scale have speeds beginning at 74 mph. One Kentucky county recorded a gust higher.
