A tropical depression is a tropical cyclone that has maximum sustained surface winds (one-minute average) of 38 mph (33 knots) or less. A tropical storm is a tropical cyclone that has maximum sustained surface winds ranging from 39-73 mph (34 to 63 knots).
Which is worse tropical storm or depression?
Here’s the difference. Tropical depressions form when a low-pressure area is accompanied by thunderstorms that produce maximum winds below 39 miles per hour. As for tropical storms, those are more severe. Depressions become storms when winds reach between 39 and 73 mph.
What’s the difference between a depression and a storm?
A tropical depression forms when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. An upgrade to a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust between 39 mph and 73 mph.
What is the single main difference between a tropical depression tropical storm and hurricane?
Wind speed is actually the only factor separating a tropical storm from a hurricane. For instance, a hurricane has to have sustained winds of 74 MPH or more, and a tropical storm can have sustained winds that are 73 MPH or less, according to the Weather Channel.
What is the difference between a depression a storm and a typhoon?
When used as nouns, tropical depression means organized low-pressure system of thunderclouds with closed surface circulation and maximum sustained winds of less than 34 knots (63 km) per hour, whereas typhoon means a weather phenomenon in the northwestern pacific that is precisely equivalent to a hurricane, which …
What is tropical depression?
(meteorology) A region of low pressure that develops into a hurricane or tropical storm. … noun. A tropical cyclone having sustained surface winds less than 39 mi (63 km) per hour.
What are the 3 stages of tropical cyclones?
Meteorologists have divided the development of a tropical cyclone into four stages: Tropical disturbance, tropical depression, tropical storm, and full-fledged tropical cyclone. When the water vapor from the warm ocean condenses to form clouds, it releases its heat to the air.

Increased rainfall can cause more widespread flooding, and powerful winds can take down larger structures.
Are tropical storms worse than hurricanes?
Hurricanes and tropical storms are both types of tropical cyclones. The difference is in the intensity. A hurricane is the most intense type of tropical cyclone with sustained winds of 74 mph or higher. Sometimes, damage caused by hurricanes is not covered by traditional homeowners’ insurance policies.
Is a hurricane stronger than a storm?
