List of Atlantic hurricane records (Prism55)

Since the reliable record keeping of tropical cyclone data within the North Atlantic Ocean began in 1851, there have been over 1,600 systems of at least tropical storm intensity and over 900 of at least hurricane intensity. Though a majority of these tropical depressions have fallen within climatological averages, prevailing atmospheric conditions occasionally lead to anomalous tropical systems which at times reach extremes in statistical record-keeping including in duration and intensity. The scope of this list is limited to tropical cyclone records solely within the Atlantic Ocean and is subdivided by their reason for notability.

Intensity
The intensity of a tropical cyclone is determined by either the storm's maximum sustained winds or lowest barometric pressure. The following table lists the most intense Atlantic hurricanes in terms of their lowest barometric pressure (millibars).
