Tropical Depression Seven forms as storm activity increases in the Atlantic
- A new tropical depression has formed in the central Atlantic after a notable period of inactivity.
- Forecast models suggest it will strengthen into Tropical Storm Gabrielle later today.
- The increased tropical activity marks a shift as conditions become more favorable for storm formation.
On September 17, 2025, a new tropical depression termed Tropical Depression Seven formed in the central Atlantic Ocean, marking the end of an unusual three-week period without storm activity during the peak of the Atlantic hurricane season. With maximum sustained winds reaching 35 mph, the depression is positioned less than 1,200 miles east-southeast of the northern Leeward Islands and is tracking westward at 13 mph. Forecasters predict that it may strengthen into Tropical Storm Gabrielle by the end of the day as environmental conditions appear conducive for its development. The area has had a lack of tropical activity, following a couple of weeks where atmospheric conditions, such as dry, stable air, hindered storm development. Historically, 60% of tropical activity occurs after September 10, indicating that the latter half of the hurricane season often sees an uptick in cyclonic activity. Current forecasts estimate a west-northwestward motion for the depression, with the potential to become a Category 1 hurricane by the weekend. Despite this, there are no immediate threats posed to land. Meanwhile, another tropical wave is being monitored, but its development potential appears low. This significant uptick in tropical activity thus highlights the increased chances for further storm developments in the Atlantic Basin as we proceed into the fall season.
