The first named storm of the 2018 hurricane season made its debut before the season officially began. Often, these storms have a radius of maximum winds which is farther out than what is observed for purely "tropical" systems.
The difference between a "subtropical' and "tropical storm" is just a structural one that scientists used to distinguish the storms". The "subtropical" designation is a weather science nuance.

"A subtropical storm typically has a large, cloud-free center of circulation with very heavy thunderstorm activity in a band removed at least 100 miles from the center", Coffee County Emergency Management Agency director James Brown said Friday.

The storm is forecast to come closest to South Florida late Saturday night and early Sunday morning - although it will remain well out in the Gulf of Mexico.
