The U.S. National Hurricane Center said Sunday that a non-tropical low-pressure system located about 180 miles east of North Carolina has a 70% probability of strengthening into a tropical storm within 48 hours. Designated Invest 95L, the disturbance is producing disorganized showers and thunderstorms along a stalled frontal boundary as it moves east-northeast at roughly 10 mph, away from the U.S. mainland. If the system attains sustained winds of at least 39 mph it will be named Dexter, the fourth named storm of the 2025 Atlantic season. Forecasters expect environmental conditions to remain supportive through Monday, after which increasing wind shear should limit further development. While no direct coastal impacts are anticipated, the associated moisture could enhance rainfall across parts of the Southeast early this week. The hurricane center is also monitoring a large tropical wave expected to emerge off Africa, giving it a 30% chance of development over the next seven days. The Atlantic season, which runs through November, historically becomes more active from August onward.
