Visiting the Central Meteorological Station, Hui said China was in a major flood and typhoon period, and meteorological agencies should follow changes in weather patterns, especially of typhoons, and step up scientific evaluations of meteorological disasters.

The meteorological office said Kaemi carried less rain than Bilis, but caused fresh damage in areas already hit by Bilis, which killed 612 people and left 208 missing in southern China.

South China's Guangdong Province also reported two deaths, while local authorities are still counting the missing and affected population, Xinhua said.

Kaemi triggered floods and landslides in Central China's Hunan Province on Wednesday, leaving three people missing.

Kaemi, the fifth such storm of the year, made landfall in Taiwan and also hit East China's Fujian Province.

This year, typhoons came earlier and stronger than before, said Er Jingping, general secretary of Office of State Flood Control and Drought Relief Headquarters. The flood season lasted longer than usual and affected more people.
