What is the minimum wind speed for a tropical storm?

Answer by  Ginny (2251)

When wind speeds reach thirty-nine miles per hour, or 34 kilometers per hour, or 18 m/s, the weather condition is considered a tropical storm, which is also known as a tropical cyclone. The winds and rainfall are more powerful in the center of the storm, and the rainfall toward the outside forms bands.

The minimum wind speed for a tropical storm is 39 mph or 62 km/h. Wind speeds of 23-38 mph / 37-61 km/h are considered a tropical depression.
