China has activated an emergency response mechanism for potential damages from two upcoming typhoons.

Meteorological authorities have forecasted that typhoon Linfa will move toward the coastal area between Guangdong and Fujian Provinces tomorrow.

Typhoon Chan-hom will move towards the coastal area of Zhejiang and Fujian on Friday night.

The two typhoons will both bring heavy torrential rains to eastern and southern parts of China.

Dong Lin with China's Central Meteorological Observatory says Chan-hom may be much more destructive than Linda due to its more powerful strength.

"Chan-hom may combine with the midlatitude system, bringing a cold front and thus bringing more rainfall. Since it's a tropical cyclone, it'll bring abundant moisture. If Chan-hom doesn't combine with the system, the rainfall brought by the typhoon itself may decrease a bit. But all in all, the typhoon will definitely deeply affect the rainfall in east China and might deteriorate previous damages."

Locals in the areas affected by the two typhoons have been advised to stock daily necessities for one to three days, and emergency mechanisms for disaster relief might be initiated if necessary.
