Part of the 1961 Pacific typhoon season

Typhoon Violet was an unusually intense super typhoon that made landfall in Japan in early October 1961. It was the second strongest typhoon of the year with wind speeds up to 205 mph, which made Violet the third strongest tropical cyclone in terms of 1 minute sustained winds, Just behind Typhoon Nancy in the same year and Hurricane Patricia in 2015.

Violet was first observed as a small circulation to the southwest of Marcus Island. On October 2, the system had organized enough to warrant further investigation. After a few days of observation, a report of tropical storm force winds was relayed back to the JTWC and on October 4, it was upgraded to Tropical Storm Violet. Violet took an unusual track, moving in a southern direction after formation. This was due to its location west of a high-pressure system, which the storm struggled to move around. After completing a curve to the south of the ridge, Violet quickly intensified into a typhoon. The movement of the subtropical ridge to the east resulted in Violet turning abruptly to the northwest. Violet continued to intensify and soon reached its peak intensity, on October 7, with sustained winds of 205 mph (330 km/h) and a minimal surface pressure of 886 hPa (26.2 inHg);[1] however, the wind readings during this era of reconnaissance were erroneously high. Violet moved in a smooth path northward and clipped the Boso Peninsula area of Japan, near Tokyo. After landfall, Violet began to transition into an extratropical cyclone and continued to move northward. By October 10, Violet had become fully extratropical.[2]

Impact

Violet was an intense storm, yet did not impact any landmass at or near peak intensity. On Guam, damages were light, mostly consisting of crop damage. The effects on Japan were generally minimal due in part to early preparation. A 9124-ton freighter, The Pioneer Muse, was left stranded on the Daitō Islands during the passing of the typhoon on October 9. All men on board were saved and later the cargo of military hardware was scavenged.[3] Another ship, The Sheik, also was stranded a few miles from The Pioneer Muse, it would later break in two due to rough seas. Two fatalities were reported in Japan due to the passage of Violet.[2]
