The "life cycle" of a tropical depression (Arlene)
The 6 images below show the typical development of a (Bermuda) tropical depression.
This depression did not strengthen into a either tropical storm or a hurricane.
These typically form out in the Atlantic Ocean, head westward towards land, and then turn north/northeast.

The initial landfall of this depression was the northeastern Florida coast. There, the back edge caught the front edge (June 25 image), consolidating things more for a bit (June 26-27).
However, these depressions start to lose their shape and power when they touch land--they draw their power as heat from the warm ocean.
Note on June 28 how the system is centered over Massachusetts but is barely discernable as a unit.
By June 29, the system has dissipated.
