Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [6] Some storms may have particularly high or low pressures that do not match with their wind speed. For example, Hurricane Sandy had a lower pressure than expected with its associated wind speed.

However, with a barometric pressure of 895 mbar (hPa; 26.43 inHg), Rita is the strongest tropical cyclone ever recorded in the Gulf of Mexico. [64] In between Rita and Katrina is Hurricane Allen. Allen's pressure was measured at 899 mbar. Hurricane Camille is the sixth strongest hurricane on record.
Saffir gave the proposed scale to the NHC for their use, where Simpson changed the terminology from "grade" to "category", organized them by sustained wind speeds of 1 minute duration, and added storm surge height ranges, adding barometric pressure ranges later on. In 1975, the Saffir-Simpson Scale was first published publicly.
Hurricane and tropical storm warnings are in place for over 42 million people in Florida, Georgia and Alabama, according to the National Weather Service. Watch USA TODAY's coverage of Hurricane Helene
The strongest tropical cyclone to make landfall on the state was the 1935 Labor Day hurricane, which crossed the Florida Keys with a pressure of 892 millibars (26.3 inHg); it is also the strongest hurricane on record to strike the United States. Out of the ten most intense landfalling United States hurricanes, four struck Florida at peak strength.
