witnessed its highest discharge since at least 1892, and the San Pedro River saw its sixth-highest crest since 1913. At least of farmland were inundated, and about 90 homes were damaged mainly near Nogales, Arizona, though some property damage occurred throughout Amado, Green Valley, and Sahuarita as well. In addition, about 175 families were evacuated from Nogales; in the aftermath of the rains, residents were asked to conserve water after the city's wells were inundated with mud and rendered unusable. Two bridges were destroyed while an additional twelve to fifteen were damaged, in addition to telephone lines and other utilities. Damage equated to about $14.6 million. Other systems Despite the season featuring the lowest number of tropical storms on record at the time, there were numerous tropical depressions that failed to intensify into named storms. The first two tropical depressions existed from May 25–30 and from May 30–June 1, both west of the Honduras–Nicaragua border. Tropical depressions Six and Seven occurred in quick succession from July 8–9 and July 9–10, respectively. Tropical Depression Eight occurred solely on July 25, while Tropical Depression Nine existed from August 1–2. Yet another cyclone existed from September 3–4, while the seventeenth and final unnamed system formed on October 22 and dissipated on the next day. Storm names The following list of names was used for named storms that formed in the Eastern North Pacific in 1977. This is the same list used in the 1973 season. This is also the final year that this list was used, as the practice of using all-female names for tropical cyclones was replaced with a mixture of male and female names beginning in 1978.
