It officially started on May 15, 1961, in the eastern Pacific and lasted until November 30, 1961. Ten tropical cyclones, 9 named storms (Madeline and Simone were operationally considered a tropical storm) and two hurricanes formed during the 1961 season, none of the hurricanes reached beyond category 1 status on the Saffir-Simpson Hurricane Scale.Unisys 2007 1961 Pacific Hurricane Season 2011-02-03 http://weather.unisys.com/hurricane/e_pacific/1961/index.html The 1961 Pacific hurricane season featured only one notable tropical cyclone: Hurricane Tara. Tara devastated southwest Mexico, causing 436–500 fatalities, making it the fourth deadliest tropical cyclone in the Eastern Pacific basin. Season summary The 1961 Pacific hurricane season was slightly more active than 1960, which had eight tropical cyclones, compare with 11 during this year. However, in 1960, there were five hurricane, but only two in 1961. Although there were an abnormally high number of tropical cyclones for its time, 1961 fell below the 1995-2008 average number of tropical cyclones, which is 15 tropical cyclones, 9 hurricanes, and 4 major hurricanes.http://www.cpc.ncep.noaa.gov/products/Epac_hurr/background_information.html Background Information: East Pacific Hurricane Season 2010 Climate Prediction Center 2011-02-03 In addition, there were eleven tropical cyclones, two hurricanes, but no major hurricanes. However, in post-analysis, it was noted that "Tropical Storm Madeline" was only a tropical depression, and shouldn't have been named. Tropical cyclone activity first began about a month after the official start of the season, with Iva developed on June 9. After Iva dissipated on June 11, there was another period of lack of tropical cyclogenesis for almost a month, ending after Tropical Storm Joanne developed on July 10. July was an active month, with four tropical cyclones developing. However, the month of August and September combined featured only two tropical cyclones. After September, there were two tropical cyclones in October, both existing only on October 3 and October 4. Two more tropical cyclones developed in November, which was the first time on record, and would not occur again until 2006. Operationally, the San Francisco Weather Bureau issued advisories for Tropical Storm Simone, which existed in early November south of Mexico. The system originated from the remnants of Atlantic Hurricane Hattie, crossing into the basin on November 1; on the same day, the system was named Simone. The system consisted of a broad circulation with gale force winds, which the Atlantic hurricane reanalysis committee referred as a Central American gyre; as it lacked a well-defined center, the system was removed as a tropical cyclone in 2019. The gyre intensified before moving ashore Mexico on November 3, whereupon it dissipated.Sandy Delgado Christopher Landsea Brenden Moses Reanalysis of the 1961–65 Atlantic hurricane seasons https://www.aoml.noaa.gov/hrd/hurdat/metadata-1961-1965.pdf 80–90 Hurricane Research Division 2019 November 26, 2019 Systems Hurricane Iva EPac Hurricane Iva weather map, June 10, 1961.jpg Iva 1961 track.png June 9 June 11 75 984 http://www.ncdc.noaa.gov/IPS/cdns/cdns.html Hurricane Iva was the first storm of the season, as the Eastern Pacific continued through the name lists regardless of the year. Iva was first observed on June 9 280 mi (420.61 km/h) southwest of Puerto Ángel. The storm slowly curved northward, and Iva did not intensify past its peak with winds of 85 mph (140 km/h). By June 11, Iva made landfall near Zihuatanejo, Guerrero, Mexico at the same intensity. Iva transitioned into an extratropical cyclone less than six hours later, and the remnants completely dissipated on June 12.

Winds were at 50 mph (80 km/h) upon development, and no further intensification would occur while Joanne headed generally westward. Joanne dissipated two days later 883 mi (1421 km/h) south-southeast of Guadalupe Island.

The names came from a series of four rotating lists. Names were used one after the other without regard to year, and when the bottom of one list was reached, the next named storm received the name at the top of the next list.http://australiasevereweather.com/cyclones/2008/summ0711a.htm Monthly Global Tropical Cyclone Summary: November 2007 First Installment Gary Padgett July 11, 2008 Australian Severe Weather February 24, 2024 Iva Joanne Kathleen LizaMadeline Naomi Orla PaulineRebecca SimoneSimone was operationally considered a tropical storm, but was removed as a tropical cyclone following HURDAT reanalysis in 2019.
