The eastern coastal provinces are bracing for the approach of Typhoon Muifa, which could be the strongest storm to hit the region in years. Provincial meteorological authorities expect the typhoon to make landfall in Zhejiang tonight or during the day tomorrow. Railway authorities in Shanghai said high-speed train services to and from Shanghai and nearby cities such as Wenzhou, Hangzhou and Ningbo might have to be suspended as the typhoon approaches. Authorities blamed lightning for the high-speed train crash in Wenzhou, Zhejiang last month that killed at least 40 people. In waters off Zhejiang, more than 4,000 vessels have been called back to ports in the cities of Ningbo and Taizhou. Coastal residents were also preparing to evacuate yesterday. Muifa is the ninth typhoon to hit China this year - and is also one of the most powerful in the past decade. It was located 745 kilometres southeast of Zhoushan city in Zhejiang yesterday morning. Meteorologists said it was packing winds of up to 162km/h near its centre and heading northwest at about 10 to 15km/h, according to a Xinhua report. Jiangsu authorities remained on high alert last night, particularly those involved with transport and maritime affairs. They were planning disaster relief in accordance with the typhoon's expected path. In Fujian province, some 5,000 fishing vessels were also called back. The National Marine Environmental Forecasting Centre is expecting waves of nine to 12 metres high in the East China Sea. Muifa is also expected to move north across South Korea. At least 70 people were killed in the Philippines when Muifa and Tropical Storm Nock-ten battered the country, bringing heavy rainfall and severe flooding.
