Atlantic Hurricane Outlook – October 3, 2025
Imelda now post-tropical, swells and rip currents remain key concern for East Coast
Atlantic Basin Overview
Post-Tropical Imelda
Imelda has transitioned to a post-tropical cyclone after passing near Bermuda. While it no longer maintains full tropical structure, it continues to generate strong winds, rain, and ocean swell. Impacts are now mostly marine and coastal in nature rather than landfall risks.Humberto & Other Waves
Humberto has lost tropical characteristics and merged with mid-latitude systems, but its residual energy still contributes to elevated surf and rip current conditions along the U.S. East Coast. Other Atlantic disturbances remain weak and suppressed by environmental constraints.
Environmental Conditions
Sea Surface Temperatures (SSTs):
SSTs beneath Imelda’s path remain moderately warm, but cooler waters ahead are aiding its weakening and limiting further tropical regeneration.Wind Shear:
Increasing vertical wind shear is disrupting Imelda’s convection and hastening its transition away from tropical structure.Humidity & Dry Air / SAL:
Dry mid-level air and Saharan dust continue to intrude, especially around weaker disturbances, suppressing convective activity and impeding new development.
Gulf of America & Caribbean
The Gulf of America and Caribbean remain calm with no organized tropical systems. Only typical late-season convection (afternoon storms) is present.
Florida & Eastern U.S. Forecast
Florida will remain outside the core of Imelda, though elevated surf, swell, and rip current conditions persist along Atlantic beaches. The broader Eastern U.S. coast should continue to monitor marine impacts and occasional squalls driven by Imelda’s remnants.

TL;DR – October 3 Snapshot
Imelda is now post-tropical but still influencing coastal waters.
Humberto has transitioned to an extratropical system, but contributes to marine hazards.
Environmental factors (cooling waters, shear, dry air) continue to weaken Imelda and suppress new development.
Gulf and Caribbean remain quiet.
East Coast marine impacts (surf, rip currents) are the primary hazard now.
