Editing Subtropical cyclone (section)

===Intensity===
Subtropical cyclones can have maximum [[wind]]s extending farther from the center than in a purely tropical cyclone and have no [[weather front]]s linking directly to the center of circulation. In the [[Atlantic Ocean|Atlantic]] Basin, the [[United States]] [[National Oceanic and Atmospheric Administration|NOAA]] classifies subtropical cyclones similarly to tropical cyclones, based on maximum sustained surface winds. Those with winds below 18&nbsp;[[Metre per second|m/s]], (65&nbsp;[[Kilometres per hour|km/h]], 35&nbsp;[[knot (unit)|knots]], or 39&nbsp;[[Miles per hour|mph]]) are called subtropical depressions, while those at or above this [[speed]] are referred to as subtropical storms.<ref>National Hurricane Center (2009).

Subtropical cyclones with hurricane-force winds of 33&nbsp;m/s, (119&nbsp;km/h, 64&nbsp;knots, or 74&nbsp;mph) or greater are no longer recognized by the National Hurricane Center. Once a subtropical storm intensifies enough to have hurricane-force winds, it is then automatically assumed to have become a fully tropical hurricane even if it still has subtropical characteristics.<ref name="Wunderground">{{cite web|last1=Masters|first1=Jeff|title=Tropical, subtropical, extratropical?|url=https://www.wunderground.com/hurricane/subtropical.asp|website=Weather Underground|access-date=4 August 2017|archive-date=30 August 2018|archive-url=https://web.archive.org/web/20180830234055/https://www.wunderground.com/hurricane/subtropical.asp|url-status=live}}</ref> Despite this however, prior to the start of modern policies in the Atlantic there were two subtropical cyclones, one in [[1968 Atlantic hurricane season#Subtropical Cyclone One|1968]] and another in [[1979 Atlantic hurricane season#October subtropical cyclone|1979]], that attained hurricane-force winds while subtropical.{{Atlantic hurricane best track}} In addition, one system, [[2000–01 South-West Indian Ocean cyclone season#Subtropical Depression 11|Subtropical Depression 11]] during the [[2000–01 South-West Indian Ocean cyclone season]], was analyzed by the [[Joint Typhoon Warning Center]] (JTWC) to have reached hurricane strength as a subtropical cyclone, but [[Météo-France]] (MFR) only considers it to have been a subtropical depression.<ref>{{cite report|author=Kenneth R.
