Tropical Storm Dexter has formed over the western Atlantic, becoming the fourth named storm of the 2025 Atlantic hurricane season. As of Monday (August 4), Dexter was located about 250 miles northwest of Bermuda, with sustained winds of 45 mph and a central pressure of 1002 mb. The storm is moving east-northeast at 14 mph and is expected to remain over open waters, posing no threat to the United States or Bermuda.
Dexter developed from a stalled front a few hundred miles east of the North Carolina coast and about 300 miles west-northwest of Bermuda. The storm's formation was aided by unusually warm sea surface temperatures, which are about 1.5 degrees Celsius above average for this time of year.
The National Hurricane Center (NHC) predicts that Dexter will not strengthen significantly due to high wind shear and dry air. The storm is expected to become a post-tropical cyclone by Wednesday (August 6) as it moves further into the Atlantic. WESH reports that Dexter poses no threat to Florida or any other land areas.
In addition to Dexter, the NHC is monitoring two other disturbances in the Atlantic. One is a tropical wave near the coast of Africa with a 50% chance of developing into a tropical depression or storm later this week. The other is a low-pressure area expected to form near the southeastern U.S. coast, with a 30% chance of development over the next seven days. AL.com indicates that these systems are not immediate threats to land but will be closely monitored.
