A storm system dubbed "Subtropical Depression Seventeen" is expected to intensify into a subtropical or tropical storm by late Wednesday, but the current forecast has the system moving east out into the Atlantic Ocean over the next two days.
According to the National Hurricane Center (NHC), the storm was about 670 miles south-southwest of Bermuda as of 11:00 a.m. Wednesday.
The system is subtropical in nature, which means, according to modeler Risk Management Solutions (RMS), that it has some characteristics of both a tropical and an extratropical depression. "The structures of a tropical and subtropical depression are different. Subtropical storms have maximum winds extending farther from the center than in a purely tropical cyclone," RMS said. "Importantly, tropical cyclone intensification processes usually occur on much shorter time scales than those associated with subtropical cyclones."
RMS noted that the NHC is expecting Subtropical Depression Seventeen to become purely tropical in nature.
The NHC said heavy rainfall is possible in the Northern Leeward Islands, the Virgin Islands and Puerto Rico "during the next day or so."
The storm is not expected to make landfall as it turns to the north and then east tomorrow and Friday.
