The lowest confirmed barometric pressure reading, 955.0 mb (28.20 inHg), for a non-tropical system in the continental United States (CONUS) was recorded during this storm at Canton, New York. [2] [3] This broke the record low of this type set by the January 1886 Blizzard. The lowest pressure reading of this type was later equalled on March 7 ...
Cyclone Dirk, this was the lowest barometric pressure observed at any site in the British Isles, and the deepest depression to pass close to the British Isles, since 8 December 1886, 936.4 hPa at Stornoway was reported on minute observations at 12:29, with 936.8 hPa recorded at the 13:00 hourly observation.

Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan , Sudan. [ 8 ]
On January 26, the third-lowest atmospheric pressure recorded in the mainland United States, apart from a tropical system, occurred as the storm passed over Mount Clemens, Michigan. There, barometer readings fell to 956.0 mb (28.23 inHg). [2] In Detroit, air pressure fell to 28.34 inches of mercury (960 mbar).
Hurricane Patricia had the second-lowest pressure and highest wind speeds ever recorded in a tropical cyclone. There are several different methods to derive pressure from wind speed and vice versa in tropical cyclones. Both information minimum pressure and wind speed have their utilities.
The following table lists the most intense Atlantic hurricanes in terms of their lowest barometric pressure. In terms of wind speed, Allen from 1980 was the strongest Atlantic tropical cyclone on record, with maximum sustained winds of 190 mph (310 km/h).
The most intense storm by lowest pressure and peak 10-minute sustained winds was Typhoon Tip, which was also the most intense tropical cyclone ever recorded in terms of minimum central pressure. Storms with a minimum pressure of 899 hPa (26.55 inHg) or less are listed. Storm information was less reliably documented and recorded before 1950. [6]
