What is a tropical storm with winds up to 40 and 73 miles per hour?

A tropical storm with winds 40 to 73 miles per hour is just that a tropical storm or a tropical depression.

To be classified as a hurricane the storm must have sustained winds of 74 mph.

 Hope this helps. :)

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
