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
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.

The 2011 Super Outbreak was the largest tornado outbreak spawned by a single weather system in recorded history; it produced 367 tornadoes from April 25–28, with 223 of those in a single 24-hour period on April 27 from midnight to midnight CDT, [4] [11] fifteen of which were violent EF4–EF5 tornadoes. 348 deaths occurred in that outbreak, of which 324 were tornado related.
Tropical cyclone wind speed climatology is the study of wind distribution among tropical cyclones, a significant threat to land and people. Since records began in 1851, winds from hurricanes, typhoons and cyclones have been responsible for fatalities and damage in every basin.
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 ...
