Will an Atlantic tropical cyclone reach hurricane strength during the window?

Observation window: 2026-08-16T00:00:00Z–2026-08-31T23:59:59Z. Yes if any NHC public advisory in-window classifies an Atlantic-basin system as a hurricane (sustained winds ≥64 kt). No only after the window ends with no such advisory. Ignore later best-track reanalysis. Void if NHC records cannot establish the answer by 2026-09-04T23:59:59Z. The primary source controls; use the named fallback only after 24 consecutive hours of primary unavailability. If both remain unavailable for 72 hours after this item's terminal deadline, or conflict materially without issuer reconciliation within seven calendar days, void. Later corrections change a result only where this item says so; otherwise the first published official record controls.

Starting Forecast source: Launch-slate research prior (2026-07-31); not equal prior.
