Hurricane Nolo reached a confirmed peak intensity of 155 mph sustained winds, placing it firmly in Category 4 on the Saffir-Simpson scale according to National Hurricane Center and Central Pacific Hurricane Center advisories. This outcome aligns with the market's near-certain trader consensus, driven by official intensity data showing rapid intensification to that threshold in late September before environmental factors like increasing wind shear and cooler waters prompted weakening. The storm maintained Category 4 strength long enough for verification before dissipating on October 11. Only a post-event revision to the official best-track record or an unexpected reanalysis could alter resolution, though historical precedents indicate such changes are rare once the system has fully dissipated.
