. On September 9, six more ships reported winds of 35 mi/h from the system, which was at 13°N, 101°W at the time, and the system was given depression status on the same day. Later that day, satellite pictures clearly showed the vortex and center of the developing cyclone, and on September 10, the first report of tropical storm force winds were reported south of the low by the ship Builder, which showed winds of 40 mi/h. The depression continued to develop at a rapid pace, with large feeder bands which helped to absorb moisture to strengthen the cyclone extending from the center, which was becoming better defined. One of the feeder bands developed near Manzanillo, Colima

, which reported winds of 45 mi/h from the band prior to daybreak. Towards the end of the day, the Allison Lykes reported 60 mi/h winds from the cyclone and, early on September 11, sufficient evidence that the depression had reached tropical storm status resulted in the cyclone being upgraded and named "Naomi".

For the next twelve hours, Naomi continued to rapidly intensify, with feeder bands flowing into a tightening spiral structure in the center of the storm. Ship reports around this time showed winds of 60 mi/h to 65 mi/h. Towards midnight, a computerized mosaic showed a clear eye and Naomi was upgraded to hurricane strength early on September 12 while at 19.8°N, 106.8°W based on the mosaic, an intensity that was verified by the Meisei Maru, which reported winds of 75 mi/h at 6:00 Greenwich Mean Time

. Although the highway reopened soon afterward, some areas that were struck by the hurricane were still rough. Naomi's most notable impact in Mexico involved the Lázaro Cárdenas Dam on the Nazas River, which was not complete by the time the hurricane hit. The dam, upriver from Gómez Palacio and Torreón, was feared to break down from the water being built up behind it, influenced by the hurricane. The two options were to either open the dam, saving Torreón by inundating Gómez Palacio, or risk inundating both towns by keeping the dam closed. The decision was made harder by the fact that, if the dam was released and no rain fell to refill the basin behind the dam, the farms would have insufficient water for agricultural growth. Photography from the Environmental Science Services Administration's Automatic Picture Transmission based on the ESSA-6 weather satellite showed that the clouds from Naomi responsible for the rain had almost moved over the area near the dam. Based on the images, the authorities decided to gamble on the dam to successfully hold up, and it managed to hold back the waters without breaking. The hurricane caused four drowning deaths and $16 million in damage in Sinaloa.

This was the second time an East Pacific storm was named Naomi and the only time that a storm named Naomi in the basin reached hurricane strength. Because the effects from the hurricane were minor, the name was not retired after this hurricane and was re-used in the 1976 season
