This market will resolve to "Yes" if Tropical Storm Norbert reaches hurricane strength at any point between market creation and September 21, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Norbert reaches hurricane strength if it attains a maximum sustained wind speed (1-minute average) of at least 74 mph, corresponding to Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale, as reported by the National Hurricane Center. Reaching hurricane strength at any single advisory during the market's timeframe is sufficient to resolve this market to "Yes", regardless of the storm's intensity at other times. If Norbert does not reach hurricane strength by September 21, 2026, 11:59 PM ET, or dissipates before reaching hurricane strength, this market will resolve to "No". If the National Hurricane Center has not published any data by September 21, 2026, 11:59 PM ET, this market will resolve to "No". This market will resolve based on the operational advisory data issued while the storm is active. Any revisions to the storm's peak intensity or category published later in a post-storm best-track report or Tropical Cyclone Report will not be considered for this market's resolution. The primary resolution source for this market will be the operational advisories issued by the National Hurricane Center (https://www.nhc.noaa.gov/). If Norbert is located outside the National Hurricane Center's area of responsibility, the maximum sustained wind speed reported by the responsible Regional Specialized Meteorological Center will be used.Tropical Storm Norbert, currently packing sustained winds near 50-60 knots with improving convective organization over the eastern Pacific, sits near the threshold for hurricane status on the Saffir-Simpson scale. Moderate westerly wind shear, mid-level dry air entrainment, and a wide spread among intensity guidance models create genuine uncertainty about whether it will reach the 64-knot threshold this weekend. National Hurricane Center forecasts project gradual strengthening over warm sea-surface temperatures as shear eases, yet several solutions cap intensification or show later weakening. New satellite observations, the next model runs, and updated NHC intensity discussions over the coming 24-48 hours will likely resolve the balance by clarifying shear trends and inner-core development.
