in significant instability that allowed in quick strengthening. A hurricane hunters flight on September 12 reported winds of in the storm's northeast quadrant; as a result, the depression was upgraded to Tropical Storm Ethel. The flight observed a well-developed eye in diameter, although they only observed hurricane-force winds in one quadrant. Reassessment, however, discounted the observations of hurricane-force winds from the aircraft as being unrepresentative of Ethel's strength, and analyzed that Ethel peaked at late on September 12, with the lowest pressure reported being . Shortly after reaching peak intensity, Ethel began weakening and dissipated on September 14 to the southwest of Bermuda. September tropical depression A vigorous tropical depression moved through the Cape Verde islands on September 13, although the complete history of the cyclone is unknown. It dissipated before affecting the Lesser Antilles. Hurricane Flossy Hurricane Flossy originated from a tropical wave that moved through the Caribbean. A tropical depression formed on September 20 just east of the Yucatán Peninsula and headed northwest across the landmass. Upon entering the Gulf of Mexico on September 22, it quickly intensified into Tropical Storm Flossy. Continuing to intensify, the storm turned to the north and attained hurricane status on September 23. Bearing winds of , Flossy struck near Venice, Louisiana, on September 24 after turning to the northeast, crossing the Mississippi River Delta. The hurricane again moved into the Gulf of Mexico, continuing to the northeast and intensifying further until moving ashore near Miramar Beach, Florida, on September 25 as a strong Category 1 hurricane with winds of and a minimum pressure of . Later that day, Flossy became extratropical over Georgia after weakening into a tropical storm. The extratropical remnants moved through the southeast United States and emerged from North Carolina into the western Atlantic on September 27. The storm was last observed on October 3, near southernmost Newfoundland. Flossy was the only hurricane of the season to strike the United States. Winds in Louisiana reached , although an oil rig offshore Grand Isle reported a gust of . The storm dropped heavy rainfall along its path, peaking at in Golden Meadow, Louisiana. The rainfall and the hurricane's accompanying storm surge caused widespread flooding and beach erosion in southeast Louisiana. The flooding surmounted the eastern seawall in New Orleans, submerging an area of . Across the region, the resulting flooding drowned cattle and caused heavy crop damage. Hurricane Flossy left
