a tropical depression on October 23, northeast of Puerto Rico. Moving towards the west, the depression attained tropical storm strength shortly after formation. A ship reported a minimum pressure of 999 mbar (hPa; 29.50 inHg) in the storm's vicinity. The large system gradually strengthened the following day, reaching its peak intensity by 1800 UTC on October 24. A ship reported a minimum pressure of 993 mbar (hPa; 29.33 inHg) early the next day, the lowest pressure measured in association with the tropical storm. At the same time, the tropical storm also recurved towards the northeast. Heading towards more northerly latitudes, a gradual weakening trend began, due to the presence of an extratropical system. The tropical storm was itself absorbed by the same system on October 27. This storm may not have been named operationally due to a lack of discernible tropical characteristics. Storm names The following names were used for tropical cyclones that reached at least tropical storm intensity in the North Atlantic in 1957. However, two of such storms, the first and last, went unnamed. The name Audrey would later be retired, only the seventh name to do so. Storms were named Audrey, Bertha, Carrie, Debbie, Esther, and Frieda for the first (and only, in the case of Audrey) time in 1957.
