The Atlantic Basin’s tropical activity is below average! No one is complaining, but maybe you are wondering why?
September 10th marks the peak of hurricane season, but this year it looks different because there are no named storms in the Atlantic basin.
This lull is a rare occurrence—from August 28th to September 10th, there have been NO tropical storms or hurricanes in the Atlantic. This makes 2025 the third time this stretch of two weeks has not seen a named storm.
The Atlantic Basin is experiencing lower moisture than usual, with more pockets of drier air and Saharan dust. Dry air shuts down development because moisture is needed to feed storms.
Another factor is high wind shear, which is the change in wind speed and direction. When wind shear is high, thunderstorms trying to form into tropical systems are ripped apart or pushed away from a low-pressure system’s center, making tropical development difficult.
However, stay alert as a new tropical wave is forecasted to move off the coast of Africa later this week. This wave currently has a low chance of development over the next 7 days.
