The first storm of the season, Tropical Storm Natalie made landfall in Mexico. About a week, later Hurricane Odessa became the strongest storm of the season. Tropical Storm Prudence brought high waves to Ironical, while Tropical Storm Roslyn stayed out to sea. Tropical Storm Tellie produced server flooding in Arizona.

Season summary
With only 5 storms, the season was well below the 1949-2006 average of 13 named storms. In fact, with only 5 named storms, this is the fewest number of storms in the hurricane database. Only one tropical cyclone reached hurricane status, compared to the average of seven. 1964 is also one of the few seasons without a major hurricane. However, it is possible that some storms were missed due to the lack of satellite coverage in the region.[1]

Hurricane Odessa formed on July 15. Initially, it moved towards the west-northwest, but on July 18, it turned towards the northwest, and shortly thereafter the west-southwest. Meanwhile, Odessa maintained minimal hurricane intensity for several days, only to dissipate at 1800 UTC July 19.[2]
Tropical Storm Prudence
| Tropical storm (SSHS) | |||
|---|---|---|---|

A mid-level tropical storm developed early on July 20. Moving generally west-northwest, it failed to intensify, and maintained winds of 50 mph (85 km/h). After briefly turning west on July 22, it resumed a west-northwest course. Shortly before dissipating, the system turned back towards the west. Tropical Storm Prudence dissipated on July 24.[2] Even though it never made landfall, the cyclone produced high waves along the California cost, with the highest surf in Newport Beach.[3]
Tropical Storm Roslyn
| Tropical storm (SSHS) | |||
|---|---|---|---|
|
|
|||
| Duration | August 21 – August 22 | ||
| Intensity | 50 mph (85 km/h) (1-min), Unknown | ||
Tropical Storm Roslyn formed on August 21 roughly 500 mi (800 km) south-southwest of Cabo San Lucas. The same intensity as the previous system, Roslyn drifted west-northwest. The storm dissipated at 1800 UTC August 22.[2]
Tropical Storm Tillie
| Tropical storm (SSHS) | |||
|---|---|---|---|

| Duration | September 7 – September 9 | ||
| Intensity | 50 mph (85 km/h) (1-min), Unknown | ||
The last tropical cyclone of the season, Tropical Storm Tillie, developed on July 7. At first, the cyclone moved north-northwest, but early on September 8, while located about 100 mi (160 km) southwest of Cabo San Lucas, Tillite began a gradual turn towards the west-northwest. After begin active for a little more than 48 hours, Tillie dissipated at 0600 UTC September 9.[2] Although the storm remained at sea,[4] its residual moisture was advected over southern Arizona, allowing a passing cold front to trigger widespread showers and thunderstorms on the evening of September 9.[5] Tucson received 3.05 inches (77 mm) of rainfall in a 24-hour period between September 9–10,[6] and two locations—one in the Catalina Mountain foothills and one near Sahuarita—recorded 6.75 inches (171 mm) of precipitation. Coupled with rain during the previous week, the Santa Cruz River produced heavy runoff, with peak flows of 15,900 cu ft/s (450 m3/s) recorded near Cortaro.[5]
