When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression
Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.
If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.
However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.
