The system seems to be elongated, and that's probably why it doesn't look very impresive. Nevertheless, according to METEO-FRANCE the system has a well-defined LLC, convection around the center, and winds around 45 mph (1-min).

Most named storms in the North Atlantic are tropical cyclones as well. :lol:

Every tropical low pressure is a tropical cyclone. I mean just the name "tropical cyclone" not the exact qualification.

Looking better. NRL has upgraded it to Tropical Cyclone 16S.

It's pretty close to 90S, too (to the northwest of 16S). Fujiwara, maybe?

You know, "doe's" is the possessive form of a female deer. I believe the word you are looking for is: does (without the apostrophe).
