Southern coastal areas of Guangdong, Guangxi and Hainan will see massive downpours, as the tropical storm Nock-Ten is expected to land on Friday afternoon or evening, the National Meteorological Center (NMC) said.

The NMC issued a yellow alert for the storm, warning local authorities and the public to take precautions and intensify safety checks. The yellow alert is the second-lowest alert level in the country's four-level rainstorm alert system.

Downpours will hit the northern part of the Sichuan Basin, the southeastern part of northwest China, the central and southern areas of north China and its eastern part, the provinces of Shandong and Liaoning, the northeastern Inner Mongolia Autonomous Region and southern coastal areas.

Meanwhile, thunderstorms will hit the northwestern part of the Sichuan Basin, the municipality of Tianjin and provinces of Shanxi and Hebei.

Scorching heat will continue to hit most areas south of the Yangtze River, the municipality of Chongqing, the eastern part of Guizhou Province and the Turpan Basin in Xinjiang Autonomous Region, with temperatures predicted to reach above 35 degrees Celsius.
