Hurricane center ups odds for system near Bahamas, tracks 1 other as Tammy fizzles
The National Hurricane Center increased the chances a system near the Bahamas could form into the season’s next tropical depression or storm while also tracking a system in the Caribbean and issuing its final advisory on what had been Tropical Storm Tammy.
The area of low pressure now located in the southwestern Atlantic moved north after dropping rain over the eastern Caribbean islands this weekend and is now located a couple hundred miles east of the southeastern Bahamas showing more signs of organization.
“A short-lived tropical depression or storm is likely to form later today or tonight while the system moves west-northwestward. By Tuesday, however, strong upper-level winds and dry air should end the chances of further development,” forecasters said,.
An Air Force reconnaissance aircraft will head out to the system later Sunday.
The NHC gives it a 70% chance to develop in the next two days.
The NHC is also beginning to forecast a broad area of low pressure could form in the central or southwestern Caribbean Sea and form into a tropical system.
“Gradual development thereafter is possible while the system moves generally westward at 10 to 15 mph,” forecasters said.
The NHC gives it a 20% chance to develop in the next seven days.
Meanwhile in the central Atlantic, the NHC gave its final advisory on what had been Tropical Storm Tammy.
As of 5 a.m., now Post-Tropical Cyclone Tammy was located about 670 miles east of Bermuda moving east at 18 mph with maximum sustained winds of 40 mph.
The busy 2023 Atlantic hurricane season has already had 21 official systems including an unnamed subtropical storm in January and 20 systems since the official start of the season on June 1. Of those, 19 grew into at least tropical storms, of which seven formed into hurricanes.
The next system to form into a tropical storm would become Tropical Storm Vince with only Whitney left on the 21-letter initial storm name list before the NHC would have to venture into a supplemental list that starts with the name Adria.
Hurricane season runs through Nov. 30.
