[1] [6] On January 10, surface pressures below the system's core deepened to 979 mbar (hPa; 28.91 inHg) as the surrounding winds reached hurricane-force. [1] Concurrently, a warm-core seclusion at the upper-levels marked the transition to a more symmetric structure, [7] although convective activity near the center remained sparse. [8]
September 6. 0000 UTC (8:00 p.m. AST September 5) – Hurricane Katia intensifies into a Category 4 hurricane and simultaneously reaches its peak intensity with winds of 140 mph (225 km/h) and a minimum barometric pressure of 942 mbar (hPa; 27.82 inHg). [18] 1200 UTC (8:00 a.m. AST) – Hurricane Katia weakens to a Category 3 hurricane. [18]
8:00 a.m. AST (1200 UTC) – Hurricane Fred further intensifies into a Category 3 hurricane and attains its peak intensity with winds of 120 mph (195 km/h) and a minimum pressure of 958 mbar (hPa; 28.29 inHg), becoming the strongest known hurricane on record south of 30°N and east of 35°W.
The nor'easter became a bomb cyclone [8] on October 26–27, when its central barometric pressure dropped from 996 mbar (29.41 inHg) to 973 mbar (28.73 inHg) over a 24 hour period. During this time, at 00:00 UTC on October 27, the system also reached its peak strength with sustained winds of 70 mph (110 km/h), while located about 125 mi ...
After making landfall on Nova Scotia, the system weakened to a 960 mbar (28 inHg; 96 kPa) nor'easter on March 27, before weakening further to a 975 mbar (28.8 inHg; 97.5 kPa) storm on March 28. On March 29, the system deteriorated into a weak winter storm over Greenland , where it would remain for the next few days while slowly dissipating.
