S. Korea braces for strong Typhoon Sanba Typhoon Sanba approaching South Korea Sept. Image courtesy of Weather Underground. 16 (UPI) -- South Korea was bracing for Typhoon Sanba's landfall Sunday with 107 mph winds and the potential for as much as 15 inches of rain, forecasters said. The Korean Meteorological Administration in Seoul said the storm was about 50 miles off the southern Japanese island of Okinawa, moving northward at 15 mph, the Yonhap news agency reported. Forecasters said the typhoon would buffet South Korea most Monday through Tuesday, The Korea Times reported. Before battering Okinawa and knocking out power to 36,000 homes with 60 mph winds, Sanba flooded parts of Manila in the Philippines and 300 families had to evacuate as water rose to 6 feet in some low-lying parts of the city, NBC News said. Early Sunday, the Joint Typhoon Warning Center in Pearl Harbor, Hawaii, reported waves more than 40 feet high as Sanba moved northward. Thousands of ships returned to ports and all ferry service in South Korea was suspended, Yonhap said. Parts of the Korean peninsula are still recovering from Typhoon Bolaven, which struck last month and killed more than 60 people.
