A tropical depression in the South China Sea, edging closer to the coast of southern part of China, strengthened into this year's 16th typhoon, Tapah, on Saturday and is expected to make landfall in South China's Guangdong Province on Monday morning, bringing heavy rains to parts of the coastal areas of Guangdong and Guangxi Zhuang Autonomous Region, China Central Television (CCTV) reported on Sunday.

As Tapah approaches, strong winds and heavy rains will sweep across much of South China, with central and southern Guangdong, central and southern Guangxi, and southern Yunnan expected to see heavy to torrential rainfall. Meanwhile, rain will also persist along the Yangtze River, with Chongqing Municipality, Hubei and Anhui provinces expecting localized heavy to torrential rain.

Tapah is forecast to move northwest at a speed of 10 to 15 kilometers per hour, gradually intensifying, and is expected to make landfall along the coastal area between Zhuhai and Zhanjiang in Guangdong between the early morning and midday on Monday as a severe tropical storm or typhoon.
