Tropical Storm Arthur — 2026
Atlantic. Peak winds 45 mph (40 kt). Tropical cyclone: Jun 17 – Jun 18, 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.
