The most powerful typhoon in a decade is set to hit the Korean Peninsula early this week, weather forecasters said Sunday, prompting authorities to brace for a worst-case scenario. According to Yonhap, Typhoon Bolaven, which is named after a highland region in Laos, was moving northward at a speed of 15 kilometers per hour from southeastern waters off Japan's Okinawa as of 3 p.m., according to the Korea Meteorological Administration (KMA). The typhoon is expected to approach waters some 500 kilometers off South Korea's southern island of Jeju early on Monday, and then transit near the country's west coast before making landfall near Sinuiju, North Korea, on Wednesday.
