Atlantic Hurricane Outlook – August 9, 2025: Quiet Tropics with More Waves Brewing

*TLDR Version, Jump Here!


The Atlantic remains calm, but early signs indicate a potential ramp-up in activity. One tropical wave is weakening, while another emerging off Africa is attracting attention due to improving environmental conditions.

Atlantic Basin Overview

  • Invest AL96 (Central Atlantic):
    The tropical wave associated with AL96 has seen its convection collapse in recent days, largely due to dry, Saharan-influenced air. Development chances remain low at 0–2 days, though gradual organization may become possible in the middle of next week as the system moves northwestward .

  • New African Tropical Wave:
    A fresh tropical wave just exiting the African coast has been designated an area of interest. The NHC currently assigns a 30% chance of development over the next 7 days. Long-range models depict a perhaps more favorable environment, suggesting potential development beyond a week and possible impacts in the eastern Caribbean around August 16–17.

Key Environmental Conditions

  • Seasonal Shift Underway:
    Climatologically, the Atlantic heads into its most active phase by mid-August. Increased sea surface temperatures, decreasing wind shear, and waning Saharan dust set the stage for heightened storm activity.

Florida & Coastal Outlook

  • No threats to land are expected over the next 10 days—including Florida and the continental U.S.—according to current tropical storm patterns and long-range models.

  • Ripple Effects: Though storm formation is uncertain, increased attention should be paid to rip currents and surf conditions as system trajectories evolve.
