BEIJING - Typhoon Bolaven is expected to enter the East China Sea on Sunday bringing gales to eastern coastal areas, the meteorological authority forecast Saturday.

Bolaven, the 15th tropical storm of the year, was located over the northwest Pacific Ocean at 5 am on Saturday, 1,250 km southeast of coastal Zhejiang province. It was heading northwest at a speed of 15 to 20 km per hour, the National Meteorological Center said.

The year's 14th typhoon, Tembin, which stayed 200 km southeast of the coastal juncture area between Guangdong and Fujian provinces early Saturday, will move southwest and linger in northeastern areas of the South China Sea over the next two days, the center said.

From Sunday to Monday, moderate and heavy rains are likely to hit the central and western parts of regions along the Yellow and Huaihe rivers, as well as southeastern part of North China, with some areas seeing rainstorms, it added.
