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,
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 highest adjusted-to-sea-level barometric pressure ever recorded (below 750 meters) was at Agata, Evenkiyskiy, Russia, elevation: 261 m (856.3 ft)) on 31 December 1968 of 1083.3 hectopascals (hPa) (31.99
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 ...
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. [2]
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.
Besides producing record-low barometric pressure across a swath of the Southeast and Mid-Atlantic states, and contributing to one of the nation's biggest snowstorms, the low produced a potent squall line ahead of its cold front. The squall line produced a serial derecho as it moved into Florida and Cuba shortly after midnight on March 13.
Contemporary reports vary considerably in the reported lowest barometric pressures. The pressure recorded on the schooner Olive reasonably consistently show her lowest pressure recorded: 29.60 inches of mercury (1,002 hPa) to 29.10 inches of mercury (985 hPa) [21] or between 29.00 inches of mercury (982 hPa) and 29.10 inches of mercury (985 hPa ...
