The hurricane season in 1969 in the Atlantic officially began on June 1, 1969 and lasted until November 30, 1969. These data usually limits the period of the year after, in the most in the Atlantic basin tropical cyclones form.
The strongest storm of the year was Hurricane Camille , the seventh strongest storm in the Atlantic Basin and the second strongest storm ever observed during the landfall in the United States. Camille's landfall was near St. Louis Bay , Mississippi . There he met as a Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale to land, killing 256 people and caused a cost of 1.4 billion dollars (9.2 billion in 2005) in property damage. Other notable storms included Hurricane Francelia , which caused severe flooding in Belize and killed 100 people, Hurricane Inga , which lasted almost 25 days and was the second-longest-ever hurricane at the time, and Hurricane Martha , which caused floods and landslides in Costa Rica and Panama .
The 1969 Atlantic hurricane season was the most active on record, with 18 tropical cyclones, 12 of which reached hurricane status, through the 2005 Atlantic hurricane season , and it is still the second most active season in the basin. The likely reason for the increased activity was the large barometric pressure differentials resulting from La Niña , which also affected the 1969 Pacific hurricane season and the 1969 Pacific typhoon season . Despite the high activity, most tropical cyclones either stayed over the sea or landed with minimal force.
Meteorologists had only begun to understand the connection between tropical and subtropical storms in the late 1960s ; a number of the eighteen hurricanes of the 1969 season were therefore not named. In addition, some of the tropical storms were retrospectively classified as hurricanes.
Martha was the southernmost hurricane in history. No other hurricane made landfall as far south as Martha on Panama on November 24, 1969 . It was also the first and so far only hurricane that made landfall on Panama.
