Low-pressure systems exist on a spectrum between tropical and extratropical (non-tropical). Josephine has slipped across the spectrum in both directions several times over the past week. Originally a strong nor’easter, the system evolved into a subtropical storm on Wednesday before returning to its roots on Thursday. A subtropical storm is one that has characteristics of both a tropical and extratropical system, a sort of hybrid storm that can bring hazardous weather to the affected regions.
