The National Hurricane Center continues to track the season’s 16th named storm in Tropical Storm Philippe while keeping tabs on two other systems with a chance to become the season’s 17th.
As of 11 a.m., the center of TS Philippe was located regarding 1,160 miles east of the Caribbean’s northern Leeward Islands moving west at 13 mph with sustained winds of 50 mph. Its tropical-storm-force winds extend out 115 miles.

“This general motion is expected for the next day or two, with a gradual turn to the northwest by mid-week,” forecasters said. “Little change in strength is forecast during the next few days.”
The system is forecast to remain in the open Atlantic and is no threat to land.

Meanwhile, the NHC is keeping odds on one system in the far eastern Atlantic and one in the Gulf of Mexico with chances to become the season’s next tropical depression or storm. After Philippe, the next names on the 2023 Atlantic hurricane list are Rina and Sean.
The higher likely of the two is an area of low pressure located several hundred miles southwest of the Cape Verde Islands that has been producing a broad area of showers and thunderstorms.
“Environmental conditions are forecast to be conducive for additional development, and a tropical depression is likely to form within the next few days as the system moves west-northwestward across the central tropical Atlantic,” forecasters said.
The NHC gives it a 30% chance to develop in the next two days and 80% chance in the next week.
Down in the southeastern Gulf of Mexico is another system of disorganized showers and thunderstorms amid a surface trough of
low pressure and an upper-level trough.
“Development, if any, of this system is expected to be slow to occur over the next day or two while it moves slowly westward. The disturbance is expected to move into unfavorable environmental conditions by the middle of the week, ending its chances for development,” forecasters said,
The NHC gives it a 10% chance to develop in the next two to seven days.
Tropical Storm #Philippe is the 17th named storm of the 2023 Atlantic #hurricane season (a subtropical storm formed in Jan). This ties 2023 with 2005 for the 3rd-most Atlantic named storms through September 23 on record, trailing 2020 (23 named storms) and 2021 (18 named storms). pic.twitter.com/Hmpao3fF96

Technically, either system might become the season’s 18th official system as there was an unnamed subtropical storm in January, according to the NHC.
Other than that, every system has spun up to become at least a tropical storm and take a name from the official tropical system alphabet with only five more names before the NHC would have to dive into a supplemental name list. The letters Q, U, X, Y and Z are skipped.
Only 2005 and 2020 went beyond the 21 names of their years’ initial lists, both using letters from the Greek alphabet, a practice that has since been replaced simply with a second set of storm names approved by the World Meteorological Organization beginning with Adria.
The hurricane season runs through Nov. 30.
