In regards to Subtropical cyclones, I wonder why this is 
 
 
	Is it because it is assumed that it is a meteorological impossibility for there to be a subtropical storm that has at least 74 mph winds?
 
	 
 
	Upon further research, it seems there was a subtropical storm that was not classified as a tropical storm that had wind speeds at 70 mph. So is it that far-fetched that you could have a "Subtropical hurricane"? Sorry about being off topic. I have just wondered about this for a while.
