What Is a Tropical Depression?
Understanding the Weakest Tropical Cyclone Type
A tropical depression is the weakest type of tropical cyclone, characterized by a low pressure area accompanied by thunderstorms that produce a circular wind flow. Its maximum sustained winds remain below 38 mph (61 km/h).
Key Features of Tropical Depressions
- Weakest type of tropical cyclones
- Low pressure area with thunderstorms
- Circular wind flow
- Maximum sustained winds below 38 mph (61 km/h)
Tropical depressions can form over warm ocean waters, typically between 5 and 20 degrees north or south of the equator. They often develop within weather disturbances called easterly waves, which are low-pressure troughs in the easterly trade winds.
Tropical depressions can evolve into more intense tropical cyclones, such as tropical storms or hurricanes, if conditions are favorable. However, they can also dissipate and weaken without developing into stronger systems.
It is important to monitor the development and track of tropical depressions, as they can potentially bring heavy rainfall, flooding, and strong winds to coastal areas.
