a tropical depression by 00:00 UTC on May 26 and further intensifying into Tropical Storm Ava approximately twelve hours later. The system remained over warm waters as it moved west and then north, allowing Ava to reach a peak intensity of early on May 28. A series of subsequent reconnaissance aircraft missions documented an incomplete eye in association with the storm, although this organization soon began to fade amidst increasing wind shear and cooler ocean temperatures. Ava weakened to a tropical depression around 18:00 UTC on May 29 and dissipated less than 24 hours later. Tropical Storm Bernice A tropical disturbance was first identified early on June 25 well southwest of Acapulco, Mexico. It quickly organized into a tropical depression twelve hours later while moving west-northwest. After strengthening into Tropical Storm Bernice around 12:00 UTC on June 26, the cyclone was restricted from further development by the entrainment of low-level clouds from the north. Instead, Bernice transitioned into an extratropical cyclone early on June 28. Hurricane Claudia A tropical disturbance, embedded within a larger area of convective activity, formed early on July 1 while well south of Acapulco, Mexico. On a westward heading, the disturbance coalesced into a tropical depression by 00:00 UTC on June 3 and strengthened into Tropical Storm Claudia six hours later. Rapid development ensued thereafter as an eye became evident on satellite imagery, and Claudia attained its peak intensity as a strong Category 1 hurricane with winds of early on July 4. Progression over colder waters caused the system to weaken below hurricane strength by 00:00 UTC on July 5, coincident with the eye becoming obscured on satellite. The cyclone was downgraded to a tropical depression around 00:00 UTC on July 7, and it ultimately dissipated six hours later. Hurricane Doreen A tropical disturbance first formed early on August 11. It drifted west and organized into a tropical depression around 00:00 UTC on August 13 before intensifying into Tropical Storm Doreen a little under a day later. Data from a reconnaissance aircraft was used to upgrade the system to a Category 1 hurricane with winds of around 18:00 UTC on August 14; this constituted the storm's peak strength. Doreen turned north-northwest thereafter, briefly drifting onshore the coastline of Baja California near San Carlos as a minimal hurricane. It continued generally northwestward, weakening to a tropical storm around 06:00 UTC on August 16 before making a second
