Tropical Storm Hanna's sustained winds topped out at 35 knots, and the storm is already weakening as it crawls across the open Atlantic. The National Hurricane Center's Advisory Number 8, issued at 0900 UTC on Wednesday, Sept. 30, 2026, put Hanna's center near 33.5 degrees north, 43.9 degrees west, moving east-southeast at just 4 knots. Minimum central pressure stood at 1006 millibars, with gusts reaching 45 knots. Six hours earlier, at 0600 UTC, the center sat a short distance to the northwest, near 33.7N, 44.2W, confirming the storm's slow crawl.
Track and intensity
NHC's forecast has Hanna losing tropical characteristics within hours. The agency expects the system to become a post-tropical remnant low by Wednesday evening, then keep weakening through the rest of the week before dissipating entirely.

What NHC is watching
