The near-certain 99.7% market-implied odds against a hurricane forming by May 31 reflect the official start of the Atlantic hurricane season on June 1, when sea surface temperatures and reduced wind shear typically enable development. As of late May, National Hurricane Center monitoring shows no organized tropical disturbances or systems meeting the sustained wind threshold of 74 mph on the Saffir-Simpson scale. Historical climatology confirms pre-season hurricanes are rare, with most activity confined to June onward. While an abrupt intensification of an undetected low-pressure area remains theoretically possible before midnight, current NOAA observations and model consensus indicate negligible risk of meeting resolution criteria in the final hours.
