The National Hurricane Center identified Subtropical Depression One on Wednesday expecting a short-lived system in the far off Central Atlantic.

So what does it matter that the system morphed from sub-tropical to tropical?

But in a twist, the system turned fully tropical today with a more symmetric grouping of thunderstorms and 35 mph winds - four miles below tropical storm status.

The tropical depression was a subtropical depression until Thursday morning. Tropical Storm Bonnie formed in May 2016 off the SC coast.

The system has migrated from part tropical and part subtropical to a fully tropical system.

Should the system advance beyond the depression stage, the storm would be given a name as a result. The first name on the list for tropical storms for this year is Arlene.

The clock is ticking on strengthening of the system, however.

According to hurricane forecasters, the storm was 730 miles west-southwest of the Azores and was moving north at 14 mph. It will continue to cause rough seas over the middle of the Atlantic, however.

There are many documented cases in years past of named storms forming before the official start of hurricane season which is June 1, and those that occurred early were no indication of how active the season was overall.
