00:00 UTC on July 26. The post-tropical cyclone dissipated about 1,740 mi (2,800 km) west-southwest of the southern tip of the Baja California Peninsula later that morning. Hurricane Darby A tropical depression formed at 12:00 UTC on July 26 while positioned about 760 mi (1,225 km) south-southwest of Cabo San Lucas, Mexico from a tropical wave that entered the eastern Pacific nearly a week prior. The system quickly intensified as it curved west-northwest around a subtropical ridge, becoming Tropical Storm Darby at 00:00 UTC on July 27 and strengthening into a Category 1 hurricane early the next day. After attaining its peak as the season's first major hurricane with winds of 120 mph (195 km/h), increasing wind shear and cooler sea surface temperatures begin to weaken the cyclone. It weakened to a tropical storm at 12:00 UTC on July 30 and further to a tropical depression a day later as it entered the jurisdiction of the Central Pacific Hurricane Center. At 12:00 UTC on August 1, Darby dissipated about 850 mi (1,370 km) east of the Hawaiian Islands. Although Darby produced no impacts to land as a tropical cyclone, its remnant moisture field combined with an upper-level trough over Hawaii to produce an unstable atmosphere. General rainfall amounts of 2–5 in (51–127 mm) were recorded across the Big Island and Oahu, with a localized peak of 9.04 in (230 mm) in Kaneohe; this led to flooding and several road closures. Minor stream flooding was observed on the southeast flank of Mount Haleakalā. A rainfall total of 3.06 in (78 mm) was recorded at the Honolulu International Airport, contributing to the wettest August on record in the city. Some coffee and macadamia nut trees were damaged. Tropical Depression Six-E Operationally, an area of disturbed weather was thought to have coalesced into a tropical depression at 09:00 UTC on July 29 while located well southwest of the Baja California Peninsula. The depression was only expected to intensify slightly before entering cooler waters and interacting with outflow from nearby Hurricane Darby. By late that evening, however, its presentation on satellite imagery more resembled a trough, and the NHC discontinued advisories. In post-season analysis, the organization determined that the depression did not form until 06:00 UTC on August 1 and lasted but 24 hours. Tropical Storm Estelle A tropical wave interacted with a disturbance embedded in the ITCZ in mid-August, leading to the designation
