Lowest Central Pressure of Atlantic Storms 2025

What this chart shows
The lowest central pressure reached by each of the 13 named Atlantic storms of 2025, in millibars. For pressure the order runs the other way from wind: the lower the number, the more intense the storm, so Melissa at the top has the lowest reading.

How the data is collected
Pressures come from the 2025 entries of the HURDAT2 Atlantic best-track file published by the National Hurricane Center. Each storm's lowest value was taken from all of its best-track records while it was a tropical or subtropical cyclone, which includes the extra records NHC adds between the usual six-hourly times to mark landfalls and intensity peaks.

Background
The HURDAT2 documentation gives central pressure to the nearest millibar and marks missing values as -999; none of the 2025 Atlantic storms has a missing minimum. NHC's report on Melissa states that dropsonde data from an Air Force Reserve Hurricane Hunter aircraft showed the pressure had fallen to 892 mb. For Erin, the report puts the minimum central pressure at about 913 mb around 1800 UTC on 16 August.

Limits
A pressure reading depends on how a storm was measured. Aircraft dropsondes give a direct value, but not every storm is sampled that way, and NHC's reports describe some pressures as estimates from pressure-wind relationships instead. Pressure and wind do not always rank storms the same way: Karen, a subtropical storm with peak winds of 40 knots, reached 998 mb, lower than Jerry, Lorenzo and Chantal, which all had stronger winds.
