Tropical Depression Nine, dissipated on November 7, over three weeks before the official end of the season on November 30. Tropical cyclogenesis in the 1977 Atlantic hurricane season began with the development of a tropical depression on June 13. Activity briefly halted, until two other tropical depressions developed in the second half of July. A fourth tropical depression formed in early August. Later that month, Hurricane Anita developed on August 29. It was the latest in the season for a first named storm to form in the satellite era. September, the climatological peak of hurricane season, was its most active month. Five tropical cyclones developed, including two tropical depressions, and hurricanes Babe, Clara, and Dorothy. There were also five tropical cyclones in October – three tropical depressions, Hurricane Evelyn, and Tropical Storm Frieda. The final tropical cyclone of the season, Tropical Depression Nine, developed between the Greater Antilles and Bermuda on November 3 and dissipated by November 7. The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 25, which was the lowest ACE value since 1946. ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Systems Hurricane Anita A tropical wave spawned a tropical depression at 1200 UTC on August 29, while located about 230 miles (370 km) south-southwest of New Orleans, Louisiana. The depression moved west-southwestward and strengthened into Tropical Storm Anita early on August 30. Later that day, the storm had intensified into a hurricane. Although intensification briefly slowed, rapid deepening occurred from September 1 to the following day, when Anita peaked as a Category 5 hurricane with winds of 175 mph (280 km/h). The storm weakened slightly to a Category 4 hurricane before making landfall near Soto la Marina, Tamaulipas. It rapidly weakened inland, decreasing to tropical depression intensity early on September 3. However, Anita remained intact across Mexico and reached the eastern Pacific Ocean as a depression. Prior to becoming a tropical cyclone, the precursor to Anita dropped light rainfall in Florida. Gusty winds and storm surge effected Louisiana. At Grand Isle, storm tides above
