On shorter time-scales, variability in the maximum potential intensity is commonly linked to sea surface temperature perturbations from the tropical mean, as regions with relatively warm water have thermodynamic states much more capable of sustaining a tropical cyclone than regions with relatively cold water.

The most intense storm in the North Atlantic by lowest pressure was Hurricane Wilma. The strongest storm by 1-minute sustained winds was Hurricane Allen. Storms which reached a minimum central pressure of 920 millibars (27.17 inHg) or less are listed.
Observations indicate that size is only weakly correlated to variables such as storm intensity (i.e. maximum wind speed), radius of maximum wind, latitude, and maximum potential intensity. [ 130 ] [ 131 ] Typhoon Tip is the largest cyclone on record, with tropical storm-force winds 2,170 km (1,350 mi) in diameter.
The 2025 Atlantic hurricane season officially begins June 1 and will run for 183 days through Nov. 30.. Tropical activity can form outside these dates because warm water and favorable atmospheric ...
The 10 costliest Atlantic hurricanes as of January 2023.. As of November 2024, there have been 1,745 tropical cyclones of at least tropical storm intensity, 971 at hurricane intensity, and 338 at major hurricane intensity within the Atlantic Ocean since 1851, the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record.

This feature shows up in tropical cyclones of tropical storm or hurricane strength. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a ...
A Category 4 hurricane has winds of 113 to 136 kn (130 to 157 mph; 209 to 252 km/h), while a Category 5 hurricane has winds of at least 137 kn (158 mph; 254 km/h). [1] [3] A post tropical cyclone is a system that has weakened, into a remnant low or has dissipated and formal advisories are usually discontinued at this stage. [1]
A hurricane can be idealized as a Carnot heat engine powered by the temperature difference between the sea and the uppermost layer of the troposphere. As air is drawn in towards the eye it acquires latent heat from evaporating sea-water, which is then released as sensible heat during the rise inside the eyewall and radiated away at the top of the storm system.
