The 20th Century low pressure record onshore in the UK occurred on 20 December 1982 at Sule Skerry dropping as low as 936 hPa. 937.6 hPa was recorded at Stornoway on 20 December 1982 as the lowest barometric pressure observed anywhere in the British Isles since 1886. 931 [88] 1983, 5 January South of Iceland,
Fastest ever recorded: 484±32 km/h (301±20 mph) (3-second gust); calculated by a DOW (Doppler On Wheels) radar unit in the 1999 Bridge Creek–Moore tornado between Oklahoma City and Moore, Oklahoma, USA, 3 May 1999. Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h).
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.
A below-sea-level surface pressure record of 1,081.8 hPa (31.95 inHg) was set on 21 February 1961. [13] The lowest non-tornadic atmospheric pressure ever measured was 870 hPa (0.858 atm; 25.69 inHg), set on 12 October 1979, during Typhoon Tip in the western Pacific Ocean. The measurement was based on an instrumental observation made from a ...
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]
Toronto pressure fell to 28.40 inches, breaking its record by 0.17. The 956.0 mb (28.23 inHg) barometric pressure measurement recorded in Mount Clemens, Michigan, was the third-lowest non-tropical atmospheric pressure recorded in the mainland United States [6] and the lowest in the Central United States.

This is the lowest central pressure on record for any Atlantic hurricane, [2] breaking the previous record of 888 mbar (26.2 inHg) set by Hurricane Gilbert in 1988. [4] Wilma's intensification rate broke all records in the basin, with a 24–hour pressure drop of 97 mbar (2.9 inHg); this also broke the record set by Gilbert.
