Temperatures are expected to drop further in much of China over the next three days as the cold wave that swept north China over the weekend heads south, China's National Meteorological Center (NMC) saidin Beijing Sunday.

The temperature in northeast China and the eastern Shandong Province is expected to fall by up to 16 degrees Celsius, while central, east and south China, as well as parts of northwest and southwest China would see a temperature drop of 6 to 12 degrees Celsius, said the NMC.

Many parts of China had experienced a sharp drop in temperature during the weekend as a cold wave hit Inner Mongolia Autonomous Region, and China's north and northeast regions.

In Mohe, China's northernmost county in Heilongjiang Province, the temperature plummeted to minus 20 to 23 degrees Celsius on Sunday morning, said the NMC.

The NMC issued the second cold wave alert since the first one on Friday, advising people to put on more clothes, fasten doors and windows, and pay attention to weather reports.

Sleet and snow are expected in southern Inner Mongolia, central and eastern parts of Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region, and parts of north and northeast China, it said.

In Gansu, local weather authorities issued a yellow snowstorm alert, as snowfall is expected to become heavier over the next 12 hours.

Strong winds are expected in these areas, as well as the Bohai Sea, the Yellow Sea and the northern part of the East China Sea, the NMC said.

Regarding Typhoon Megi, the NMC has canceled an alert for it as it had weakened into a tropical depression after it landed in the southeastern Chinese province of Fujian Saturday.

But rainstorms would continue in the coastal provinces of Zhejiang and Fujian due to the typhoon's residual influence, it said.
