Going to preface all this with the reminder that this could become a Tropical Depression or even become TS Arthur, though mostly we are still in the realm of potential vs actuality. Either way, the impacts will be the same and those being torrential rain leading to dangerous flooding issues in some places, high winds and the danger of severe weather. When we say dangerous I mean they could turn deadly. Hopefully not, but the area geographically it is traversing are filled with bayous, swamps and dangers not apparent to newbies or tourists. It's hard to explain how in this neck of the world flooding can happen fast and put someone who is unaware of that into life threatening dangers.  Even for locals, dangers occur and accidents happen. I'd say this is definitely "tropical" in that it's origin is one part remnants of Cristina from the EPAC along with other ingredients and it is in the tropics and it is behaving in a tropical way bu it has not developed a real, solid center. Should and when this occurs it will be TD1 or TS Arthur. Note that the advisory discussion below shows it attaining tropical storm starus in 24 hours. This is the perfect example of why we have the Potential Cyclone category as storms often form close in along the coastline here and can intensify fast and the normal time parameters do not apply here vs  a long tracking tropical wave with potential far out in the distant Atlantic. 

You can see the spin.

It's across a broad area.

Waiting for a defined center.

Still a murky messy with spin...

...and strong convection.

Biggest problem?
