What is a subtropical storm?

Brainyblonde

A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form in a wide band of latitude, from the equator to 50°. An extratropical low may develop into a subtropical depression, which can strengthen. A subtropical storm can develop into a hurricane, and there is at least one case of a tropical storm transforming into a subtropical storm. These storms can have maximum winds extending further from the center than in a purely tropical cyclone. The maximum recorded wind speed for a subtropical storm is 33 m/s, 119 km/h, 65 knots, or 74 mph), also the minimum for a hurricane. In the Atlantic Basin, the United States NOAA classifies subtropical cyclones just as with tropical ones, based on maximum sustained surface winds: below 18m/s, 65km/h, 35 knots, or 39 MPH is a tropical or subtropical depression, and at or above this velocity is a tropical or subtropical storm. http://en.wikipedia.org/wiki/Subtropical_storm Oct 11 04, 5:13 PM
