Deadliest tropical cyclone season: 500,805+ fatalities during the 1970 North Indian Ocean cyclone season: May 2, 1970 – November 29, 1970: North Indian Ocean [9] Most tornadoes formed: 120 confirmed tornadoes: September 15, 2004 – September 18, 2004: Hurricane Ivan in the southern and eastern United States [10] Highest wind gusts: 113.4 m/s ...
The most intense tropical cyclone in the South-West Indian Ocean was Cyclone Gafilo. By 10-minute sustained wind speed, the strongest tropical cyclone in the South-West Indian Ocean was Cyclone Fantala. Storms with an intensity of 920 hPa (27.17 inHg) or less are listed. Storm information was less reliably documented and recorded before 1985. [6]
Highest forward speed of a tropical cyclone: Tropical Storm Six – 1961 – 69 mph (111 km/h) Most tornadoes spawned by a tropical cyclone: Hurricane Ivan – 2004 – 120 confirmed tornadoes [83] Smallest tropical cyclone on record: Tropical Storm Marco – 2008 – gale-force winds extended 11.5 mi (18.5 km) from storm center

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.
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

Peak Wind Speed: 175 mph. Deaths: 65. What happened: The Category 5 hurricane is considered one of the most destructive hurricanes to hit Florida. Andrew was the costliest hurricane in Florida’s ...
The August 2020 Midwest Derecho delivered a maximum measured wind speed of 56 m/s (109 kn), with damage-estimated speeds as high as 63 m/s (120 kn) in the Cedar Rapids, Iowa area. [27] The storm was referred to as one of the largest "land-based hurricanes" in recorded history spawning 17 confirmed tornadoes across Wisconsin, Illinois, and Indiana.
