System is very unorganized, with a few clusters of strong convection. Strongest cluster is on the western portion of the system (big blob in the middle of the screen).
We do expect this system to potentially develop soon, but this organization is not favorable for a tropical depression to form ATTM.
This storm is more on the smaller side according to the infrared imagery, but it could be because I am not looking at what could be the 'arms' of the storm.
Tropical Depression FIVE will become a tropical storm and move parallel to land. It will stay far away from land. The storm will eventually strengthen into a Category 1 hurricane, but that appears the worst it will strengthen to.
