Tropical Depression Four (2017)

Tropical Depression Four was an early season tropical cyclone that developed in the deep tropics, before being torn apart by dry air. The origins of the system can be traced back to a tropical wave that emerged from the coast of Africa on July 2, and whilst it was moving slowly towards the west, it slowly organised besides dry air intrusion, and became a tropical depression early on July 6. The depression was able to intensify slightly to a peak of 35 mph the following day, before opening out into a tropical wave again as dry air choked off the low level circulation. The remains of Four would continue to produce sporadic convection for the next several days, passing over Florida on July 13 before dissipating completely after bringing severe thunderstorms to the area.
