Tropical Storm Hanna weakened from a 40-knot storm to a post-tropical cyclone over roughly two days in the central Atlantic, the National Hurricane Center said, with the final classification issued at 1500 UTC on September 30, 2026.
The center, based in Miami, Florida, designated Hanna as AL082026. At 1500 UTC on September 28, 2026, Hanna carried maximum sustained winds of 40 knots (45 mph / 75 km/h) with its center near 36.6°N, 50.4°W. Those winds held steady through the early hours of September 29, then dropped to 35 knots (40 mph / 65 km/h) by 1500 UTC that day, the National Hurricane Center reported.
The storm tracked generally eastward and slightly southward across the central Atlantic between September 28 and September 30. By 1500 UTC on September 30, Hanna's center had settled near 33.4°N, 43.6°W, and maximum sustained winds had fallen further to 30 knots (35 mph / 55 km/h), at which point the center reclassified it as a post-tropical cyclone.
