Hurricane Isaias — 2026
Atlantic. Peak winds 120 mph (105 kt), Category 3. Tropical cyclone: Oct 6 – Oct 10, 2026 (UTC).
By the numbers
"Peak winds" means the strongest sustained wind NHC estimated at any point in the storm's life, averaged over one minute, not gusts. ACE adds up a storm's wind strength every six hours while it is at least a tropical storm, so a long-lived strong storm scores far higher than a brief weak one.
