A weather system is a tropical depression when it has sustained wind speed of 38 mph or less. It becomes a tropical storm when winds reach 39 mph. When those winds reach 74 mph, the storm becomes a hurricane.
Hurricanes have five categories depending on wind speeds.
The Saffir-Simpson Hurricane Scale establishes those categories and is used to estimate potential property damage. Thus far, hurricanes have not developed in the Atlantic Ocean or Caribbean Sea. There have been two tropical depressions. There was a tropical storm, named Daniel, in the North Pacific during June. That same month, Hurricane Carlotta formed in the Pacific and is believed to have caused a freighter to be lost at sea with 18 crew members.
