Nolo reached Category 4 status with peak sustained winds of 155 mph and a minimum pressure of 929 mb on September 28, 2026, as confirmed by Central Pacific Hurricane Center observations during rapid intensification amid warm sea surface temperatures and low wind shear. Official analyses show the annular hurricane structure supported this intensity before subsequent shear and dry air caused weakening, with later restrengthening to Category 3 but no exceedance of the prior peak. Trader consensus at 97.8% for Category 4 reflects this verified maximum on the Saffir-Simpson scale. A realistic challenge would require new data revisions showing Category 5 winds or an unexpected reintensification episode before dissipation, though current model trends and monitoring indicate continued weakening over open water.
