Atlantic Hurricane Outlook – September 1, 2025
On September 1, the Atlantic remains storm-free with no active cyclones. A tropical wave emerging off the coast of Africa carries a 40% chance of development over the next 7 days. While environmental conditions—wind shear, dry air, and Saharan dust—are suppressing rapid growth, the wave will be monitored closely. Florida and the Gulf of Mexico remain quiet, experiencing only typical early-September thunderstorms.

Atlantic Basin Overview
No Active Storms
There are currently no active tropical cyclones in the Atlantic basin—the first tranquil period we've seen since the wake of Fernand and Erin.Emerging Tropical Wave Off Africa
A new tropical wave has emerged off the West Coast of Africa near Guinea-Bissau. Presently disorganized, the NHC assigns it a 0% chance of development in the next 48 hours, but the probability rises to about 40% over the next 7 days. This system will be closely monitored as it moves west across the tropical Atlantic.
Environmental Conditions
Sea Surface Temperatures (SSTs): Remain warm in the Gulf and Caribbean (29–31 °C), while the open Atlantic heat content diminishes northward.
Wind Shear: Elevated shear across much of the basin continues to suppress storm formation.
Mid-Level Humidity & SAL (Saharan Air Layer): Dry air and SAL dust are widespread, inhibiting significant convection and limiting the strength of the new wave emerging off Africa.
Gulf of America & Caribbean
The Gulf remains stable and quiet, under the influence of high pressure. Only routine afternoon sea-breeze thunderstorms are expected—no tropical threats are present.
Florida & Southeast U.S. Forecast
Florida continues in its trademark late-August/early-September pattern: hot, humid, with scattered afternoon thunderstorms. With no active systems nearby, no coastal or tropical threats are expected this week.
