south of Hong Kong. The conditions around the system rapidly became unfavorable after that, and it weakened quickly, finally dissipating on the 9th. Tropical Depression 20W Typhoon Joan (Sening) A tropical disturbance organized into Tropical Storm Joan on October 10, east of the Philippines. Conditions favored strengthening, and Joan reached typhoon status on the 11th. From late on the 11th to early on the 13th, Typhoon Joan rapidly intensified to a 175 mph Super Typhoon. It struck the southeastern Luzon at that intensity on the 13th, and crossed the archipelago. After weakening to a minimal typhoon, Joan turned to the northwest, where it reintensified to a 115 mph typhoon. It made landfall on eastern Hainan Island on the 16th, and dissipated on the 18th over China. Joan left 768 people dead (with 193 missing), and caused $74 million in damage (1970 USD), mostly from agricultural losses. Typhoon Kate (Titang) Tropical Storm Kate developed just behind Typhoon Joan, east of the southern Philippines on October 14. It tracked westward as a small cyclone, and strengthened into a typhoon on the 15th. It made landfall twice, once in the Philippines and once in Vietnam, resulting in at least 631 fatalities (with 284 missing) and $50 million in damage. Typhoon Louise (Uding) Typhoon Louise (classified as a tropical storm by the JTWC) formed as a disturbance east of the Philippines. The disturbance traveled across them before it became a tropical storm over the South China Sea. It made landfall in South Vietnam and dissipated over the Gulf of Thailand. Severe Tropical Storm Marge (Wening) Tropical Storm Marge followed a similar path to Louise. It formed over the Pacific, becoming a tropical depression south of Guam. It became a tropical storm 3 days later, then crossed southern Luzon before dissipating over the South China Sea off the Vietnamese coast. Tropical Storm Nora Tropical Storm Nora formed south of Vietnam and began to strengthen, becoming a tropical storm the next day. The system passed south of Cape Cà Mau as a tropical storm before weakening and dissipating over the Gulf of Thailand. The remnants of Nora then crossed the Malay Peninsula on the 5th, and contributed to the formation of the 1970 Bhola cyclone on the 8th, which devastated East Pakistan (Modern day Bangladesh). Severe Tropical Storm Opal Tropical Storm Opal formed as a disturbance over the sea east of Mindanao, then crossed the Philippines
