The origins of Aletta are from a tropical disturbance that was first noted on May 18 about 500 mi (800 km) south-southwest of Acapulco.
On May 20, satellite imagery showed evidence of a weak atmospheric circulation.
Based on this, the disturbance was upgraded into a tropical depression.
Moving northwest, the depression became Tropical Storm Aletta 36 hours later over 86 °F (30 °C) sea surface temperatures.
The system re-curved towards the northeast due to strong upper-level westerlies, reaching its peak intensity of 65 mph (100 km/h) on May 23.

Shortly after its peak, Tropical Storm Aletta began to weaken.
However, the tropical cyclone managed to maintain winds of 50 mph (85 km/h) for 30 hours before resuming a weakening trend.
While the steering currents weakened on May 25, Aletta slowed and moved in a large clockwise loop until May 28.
Shortly thereafter, Tropical Storm Aletta was downgraded into a depression.
Tropical Depression Aletta dissipated on May 29 roughly 180 mi (290 km/h) southwest of Acapulco.
