Railway authorities in east China announced on Thursday that 341 trains in Fujian Province would be canceled from Friday to Sunday to prepare for this year's first typhoon.
Typhoon Nepartak is forecast to make a landing on the coast of Fujian on Saturday morning, bringing gales and heavy rain to the province and neighboring regions.
