MIAMI, Florida – NOAA‘s National Hurricane Center issued a Public Advisory at 11:00 a.m. Atlantic Standard Time on Wednesday, September 17, 2025, for Tropical Storm Gabrielle, which strengthened from Tropical Depression Seven and Invest 92L earlier today while moving north-northwestward across the central Atlantic.
No tropical storm watches or warnings are currently in effect.
Interests in the central and western subtropical Atlantic should monitor the progress of this system.
Tropical Storm Gabrielle is located about 1,085 miles east of the northern Leeward Islands, and is moving to the north-northwest at 22 mph (35 km/h).
NHC forecasters say that an erratic northwestward to west-northwestward motion at a reduced forward speed is anticipated across the tropical and subtropical central Atlantic during the next few days.
On the official NHC forecast track, the center of the tropical cyclone is expected to move across the central subtropical Atlantic through early next week, with no immediate coastal impacts anticipated.
Computer models, often referred to as spaghetti models, show Tropical Storm Gabrielle moving northwestward to west-northwestward across the central Atlantic, with a potential northward bend next week.
While the guidance generally agrees with this scenario, there is some spread in the forecast track, particularly regarding the northward turn and potential long-range impacts.
The official NHC forecast track is in best agreement with the GFS (American model) and the TVCN consensus model.
Tropical Storm Gabrielle has maximum sustained winds of 45 mph (75 km/h), with higher gusts.
Little change in strength is expected during the next 48 hours, but some gradual intensification is forecast over the weekend.
NOAA forecasts an “above-normal” 2025 Atlantic Hurricane Season, which runs from June 1 through November 30.
September marks the peak of hurricane season, with historical data from NOAA and the National Weather Service showing increased tropical storm and hurricane activity during this period.
