A subtropical cyclone is more likely to be a tropical cyclone than an extratropical cyclone. Subtropical cyclones are only found in the northern Atlantic Ocean and in the eastern Pacific Ocean. Like normal tropical cyclones, most subtropical cyclones have maximum wind speeds of at least 39 mph to 74 mph (60 km/h to 110 km/h). Subtropical cyclones that have wind speeds less than 39 mph are known as "subtropical depressions". There is no such thing as a "Subtropical Hurricane". If there is a previously subtropical storm with this intensity, it is either fully tropical or extratropical.
