On August 12, a tropical disturbance entered the Caribbean Sea to the south of Antigua, believed to have been a strong tropical wave.
Although meteorologist David Roth assessed the storm as making landfall on August 19 at Isle Dernière to the west of New Orleans,[REF] a research paper from the American Meteorological Society estimated that the hurricane moved ashore about 40 mi (60 km) southeast of New Orleans [REF].
