Potential Tropical Cyclone Nine is likely to become a tropical depression or tropical storm by Saturday (Sept. 14) night and will pose a threat to the Bahamas, Florida and possibly other parts of the southern United States, including areas devastated by Hurricane Dorian, according to The Weather Channel.

A “potential tropical cyclone” allows the National Hurricane Center (NHC) to issue advisories, watches and warnings on systems that have yet to develop, but pose a threat of bringing tropical-storm-force (39-plus mph) or hurricane-force (74-plus mph) winds to land areas within 48 hours.

The NHC has posted a tropical storm warning for the northwestern Bahamas, except for Andros Island. This means tropical-storm-force winds are expected there within 36 hours.

The NHC has also issued a tropical storm watch for portions of the Florida east coast, from Jupiter Inlet to the Flagler/Volusia County line. This means tropical-storm-force winds are possible there, generally within 48 hours.

Potential Tropical Cyclone Nine is moving toward the northwestern Bahamas and producing clusters of showers and thunderstorms over the islands. These convective clusters have become more persistent over the past day.

This disturbance is moving northwestward and an increase in forward speed is anticipated this weekend.
