Haikou, Ramadan 20, 1435, Jul 17, 2014, SPA -- Typhoon Rammasun is expected to make landfall in south China's island province of Hainan or coastal area of Guangdong Province on Friday, the Hainan provincial meteorological station said on Thursday. Rammasun, packing rainstorms and winds of up to 120 km per hour, is moving northwest at a speed of 20 to 25 km per hour and will probably land in Hainan or Guangdong with a maximum wind speed of more than 140 km per hour around noon on Friday, Xinhua quoted to the station's forecast as saying. China's National Marine Environmental Forecasting Center on Thursday issued a red alert for high seas likely to be generated by Typhoon Rammasun within the next 24 hours in the northern part of South China Sea, and along the coast of east Hainan and west Guangdong. China has a four-tier color-coded weather warning system, with red representing the most severe warning, followed by orange, yellow and blue. --SPA 18:01 LOCAL TIME 15:01 GMT www.spa.gov.sa/w
