The 1955 Atlantic hurricane season was, at the time, the costliest season ever recorded, just ahead of the previous year. The hurricane season officially began on June 15, 1955, and ended on November 15, 1955. It was an extremely active season in terms of accumulated cyclone energy (ACE), but slightly above average in terms of tropical storms, with 13 recorded tropical cyclones. The first storm, Alice, had persisted since December 30, 1954. Alice caused relatively minor impact as it tracked through the Lesser Antilles and eastern Caribbean Sea in early January. Tropical Storm Brenda caused two deaths and minor damage along the Gulf Coast of the United States in early August. The quick succession of Hurricanes Connie and Diane caused significant flooding in the Northeastern United States, with nearly $1 billion (1955 USD) in losses and at least 232 fatalities. The next three storms – Hurricanes Edith and Flora and Tropical Storm Five – caused very minor or no impact. In early September, Hurricane Gladys caused severe localized flooding in Mexico, primarily in Mexico City. Additionally, an offshoot of Gladys inflicted minor impact in Texas.
