BEIJING, Sept. 10 -- China's National Meteorological Center on Sunday evening renewed a yellow alert for rainstorms as heavy downpours are expected to lash parts of China.

From 8 p.m. Sunday to 8 p.m. Monday, heavy rainfall is forecast to hit parts of Guangxi, Guangdong, Hainan, Gansu, Shaanxi, Sichuan, Hubei, and Henan, said the center.

Some areas of these regions may experience heavy downpours, with maximum hourly precipitation surpassing 80 millimeters, accompanied by severe convective weather, including thunderstorms and gales.

The center has advised local governments to prepare for rainstorms and traffic management authorities to implement proper traffic control on road sections hit by heavy rainfall.

It has suggested disconnecting at-risk outdoor power supplies, suspending outdoor operations in open areas, and transferring people from vulnerable areas to safer places.

The center said work should also be done to check the drainage systems of cities, farmlands, and fishponds, and necessary drainage measures should be implemented.

China has a four-tier, color-coded weather warning system, with red representing the most severe warning, followed by orange, yellow, and blue.
