The word depression means two things, one of  them means sad and the one that  I am going to talk about is with weather.
A depression is an early stage of  a hurricane that is forming. When it is forming and it's winds get up to a speed of 23-63 mph, it's called a tropical depression. When the winds get up to 63 mph it is then called a tropical storm. When the winds are higher than 73 mph it is called a hurricane. So, if  you ever wonder what a weather depression is, it is a beginning of a hurricane.
 
 
 

If you are reading this you must want to learn about tropical storms.
 

A Tropical storm's winds start at a speed of  33-73 mph. Tropical storms can cause floods and thunder storms. Even though it is not as powerful as a hurricane it should be approached with caution.

So in conclusion, both of these topics are really cool but, very dangerous at the same time
