in San Felipe/Mexicali, while the highest total in the United States was in Sierra Ancha. Joanne also caused heavy surf in California. A young man in Phoenix was electrocuted and killed when he attempted to remove a downed power line from his car. Tropical Depression Thirteen Tropical Depression Thirteen formed on October 12. It first headed southwest, then west, and performed a cyclonic loop. It headed north before sharply recurving. It dissipated on October 18. Tropical Storm Kathleen On October 18, a vortex in the Intertropical Convergence Zone was determined to be a tropical storm through the use of satellite pictures. Kathleen was a tropical storm for only eighteen hours before weakening into a tropical depression and recurving to the northeast. The tropical cyclone dissipated on October 19 while out to sea west of Puerto Vallarta. No deaths or damages were reported. Tropical Depression Olga Just east of the dateline, the northern hemisphere component of a "cyclone twin" formed into a tropical depression October 16. After crossing the dateline, it intensified into Tropical Storm Olga of the 1972 Pacific typhoon season. After passing through the Marshalls as a tropical storm, Olga intensified into a typhoon on October 25. It then swung through part of the Northern Marianas Islands before it was absorbed by a front near Honshū on October 29. As the NMI had already been hit by Typhoon Marie three weeks earlier, little damage was reported. Hurricane Ruby An area of enhanced convection in the ITCZ close to the equator formed into a tropical depression on November 11. It headed north northwest, and intensified into Tropical Storm Ruby on November 13. Ruby then abruptly turned west and crossed the dateline, briefly reaching hurricane status. After becoming a typhoon just after crossing the dateline, the first time that had happened since 1967, Ruby steadily strengthened and eventually peaked as a moderately intense typhoon on November 16 while east of Taongi Atoll. It then steadily weakened as it headed west northwest, and wind shear destroyed the cyclone on November 20 when it was east of the Northern Marianas Islands. Ruby caused no deaths or damage. Of note is the fact that on November 17, Ruby had a central pressure of 983 mb (983 hPa), which is high for a 100-knot typhoon. Tropical Storm Liza A tropical depression formed south of the Gulf of Tehuantepec on November 13. It headed nearly due
