Two typhoons might make landfall in China in the next three days, the country's top weather observatory warned on Tuesday.

Typhoon Linfa, with its center about 390 km to the southeast of the boundary between China's Fujian and Guangdong provinces in the South China Sea as of 3 pm on Tuesday, is forecast to move northwest at a speed of 10 km per hour, and will probably hit the coast of the two provinces from Wednesday night, the National Meteorological Center (NMC) said.

Linfa is expected to bring gales of up to 30 meters per second, it warned.

Meanwhile, typhoon Chan-Hom, the center of which was 1,560 km to the southeast of the Diaoyu Islands as of 2 p.m. Tuesday, will move northwest at 20 km per hour, and enter the southern part of the East China Sea on Thursday night, the NMC forecast.

It said Chan-Hom may make landfall in Fujian and Zhejiang provinces late on Friday, bringing gales of up to 60 meters per second.
