Discussion: Climate Impact Company often mentions optimum climate normal (OCN) which identifies 5-year, 10-year, and 15-year climatology due to the vast differences in these shorter-term historical weather records with standard 30-year climatology. During 2016-24, the North Atlantic basin has shifted into a consistently more active than normal tropical cyclone pattern which represents an OCN. Various forecasts for 2025 are very close to the 9-year OCN. During 2016-24, the first tropical cyclone of the season occurred very early with only 2019 seasonal debut after the month of June while 5 of the 9 years observed the first event prior to June 1st (Fig. 1). Currently, the North Atlantic basin is ALL CLEAR (Fig. 2). Operational models indicate no tropical cyclones during the next 15 days. If so, 2025 will be only the second year of the past 10 when the seasons first event took place after the month of June.
