What are the effects of tropical depressions?
Tropical depressions are cyclones with winds that gust at 38 miles per hour (33 knots) or less. While cyclones aren’t as strong as tropical storms or hurricanes, they can bring significant amounts of rain, thunderstorms and devastating floods.
Do subtropical storms get named?
They were officially recognized by the National Hurricane Center in 1972. Beginning in 2002, subtropical cyclones received names from the official tropical cyclone lists in the North Atlantic, South-west Indian Ocean, and South Atlantic basins.
How often is the list of tropical storm names reused?
six years
For Atlantic hurricanes, there is a list of names for each of six years. In other words, one list is repeated every sixth year. The only time that there is a change is if a storm is so deadly or costly that the future use of its name on a different storm would be inappropriate for obvious reasons of sensitivity.

Which is worse tropical storm or depression?
