All hurricanes start as tropical disturbances, which are areas of unsettled weather or thunderstorms in the tropics.
The storms will begin to become a little more organized and spin, this is known as a tropical depression. A tropical depression has wind speeds up to 38 mph.
If the tropical depression strengthens and its wind speeds reach 39 mph, it then becomes a tropical storm and it is named.
Once the winds reach 74 mph, the storm is then considered a hurricane.
