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.

– Hurricane Leslie intensifies to Category 2 strength about 945 mi (1,515 km) east-northeast of the northern Leeward Islands; it simultaneously attains its peak intensity, with maximum sustained winds of 105 mph (165 km/h) and a minimum barometric pressure of 972 mbar (28.70 inHg). [108]
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.
It was also the ninth-strongest hurricane since 1900 to make landfall in Florida, based on barometric pressure. This article originally appeared on USA TODAY: Hurricane forecasters watching Isaac ...
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 Helene strengthened into an "extremely dangerous Category 4 hurricane" before making landfall along Florida's Gulf Coast late Thursday night, according to the National Hurricane Center ...
Isaac continued to strengthen into the next day, as it turned toward the northeast, intensifying to a Category 2 hurricane. This was its peak intensity, with maximum sustained winds of 105 mph (165 km/h) and a minimum barometric pressure of 963 mbar (28.44 inHg). [200]
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.
