Tropical Storm Dexter, the fourth named storm of the 2025 hurricane season, formed Sunday night as forecasters also track two other disturbances in the Atlantic Ocean, according to the National Hurricane Center.
None of the systems pose an immediate threat to Louisiana.
Dexter has maximum sustained winds of 45 mph and is moving east-northeast at 12 mph. The tropical storm is expected to move away from the United States, forecasters said.
Meanwhile, a tropical wave moving off the west coast of Africa could become a depression later this week as it moves west-northwestward across the central tropical Atlantic. The system is currently producing only limited shower activity, forecasters said, and has a 50% chance of forming within the next week.
A broad area of low pressure is also expected to develop in a couple of days a few hundred miles off the coast of the southeastern U.S. Forecasters said the system has a 30% chance of developing this week as it drifts slowly westward to northwestward.
Hurricane season runs from June 1 through Nov. 30. According to experts, the cast majority of storms form in the Atlantic after Aug. 1.
