A knot is a measure of speed, in this case wind speed. 1 knot is equal to about 1.15 miles per hour.
Isaac began as a tropical depression.
Katrina was only a tropical depression for a few hours. Soon after forming, Tropical Depression 12 became Tropical Storm Katrina.
No. A tropical depression is a tropical cyclone with winds under 39 mph. A tropical storm is a tropical cyclone with winds from 39 mph to 73 mph.
There are currently no active tropical depressions. Also, tropical depressions are given numbers, not names. The next one in the Atlantic will be Tropical Depression Fourteen. There is however, a tropical disturbance labeled 95L that has a high chance of becoming a tropical depression.
The winds of a tropical depression are not strong enough to cause much damage and there is no storm surge. However, a tropical depression still produces heavy rain, which can lead to flooding.

A tropical depression has winds under 39 mph.
A tropical depression is not a tropical storm, but can easily develop into one. Additionally, a tropical depression can still be hazardous, as the heavy rains can lead to flooding.
A tropical depression becomes a tropical storm when sustained winds reach 39 mph or greater.
No. A tropical depression is a tropical cyclone with winds under 39 mph. A tropical storm is a tropical cyclone with winds from 39 mph to 73 mph.
A tropical depression becomes a tropical storm when sustained winds reach or exceed 39 mph.
A tropical depression is more organized than a tropical disturbance. It has a closed circulation and a definite center of rotation, which a disturbance lacks.
There are currently no active tropical depressions. Also, tropical depressions are given numbers, not names. The next one in the Atlantic will be Tropical Depression Fourteen. There is however, a tropical disturbance labeled 95L that has a high chance of becoming a tropical depression.
The winds of a tropical depression are not strong enough to cause much damage and there is no storm surge. However, a tropical depression still produces heavy rain, which can lead to flooding.
A tropical depression is the weakest level of tropical cylone. Such a system has a fairly organized circulation but does not produce tropical storm force winds.
There is no lower limit for tropical depression winds, which go up to 38 mph.
