Tropical Storm Dexter formed on Sunday night, Aug. 3, becoming the fourth named storm of the 2025 Atlantic hurricane season.

Tropical Storm Dexter emerged between the Eastern Seaboard and Bermuda, as two more Atlantic low pressure systems are being tracked for development.

There’s a new tropical storm in the Atlantic Ocean, and two other disturbances that have a shot to get names as well. The National Hurricane Center named Tropical Storm Dexter late Sunday while it was several hundred miles off the coast of North Carolina. Dexter is headed away from the United States, however.
