Question: How many hurricanes happened in the year they were most active before 1969? Passage:The 1969 Atlantic hurricane season was the most active Atlantic hurricane season since 1933 and is tied with 2019 as the fourth most active Atlantic hurricane season on record, and was also the final year of the most recent positive Atlantic multidecadal oscillation (AMO) era. The hurricane season officially began on June1, and lasted until November30. The season had the highest number of systems reach hurricane status twelve in a single season, until that record was surpassed in 2005. The season was above-average despite an El Nino, which typically suppresses activity in the Atlantic Ocean, while increasing tropical cyclone activity in the Pacific Ocean. Activity began with a series of five tropical depressions, the first of which developed on May29. The third system in that series, Tropical Depression Seven, caused extensive flooding in Cuba and Jamaica in early June. The final in the series formed on July25, the same day that Tropical Storm Anna developed. Neither the former nor latter caused significant impact on land. Later in the season, Tropical Depression Twenty-Nine caused severe local flooding in the Florida Panhandle and southwestern Georgia in September. Hurricane Blanche was a small and short-lived tropical cyclone in mid-August that resulted in minimal effects.
