BEIJING — China's National Meteorological Center renewed yellow alerts for rainstorms and gales on Sept 19, calling for safety measures in multiple regions.

In the 24 hours from 2 pm on Sept 19, heavy rains and downpours are expected to hit parts of Liaoning, Shandong, and Hebei Provinces and the municipalities of Beijing and Tianjin, with the maximum rainfalls likely reaching 100 to 150 millimeters.

Parts of Henan, Anhui, Hubei, Hunan, Guizhou, Yunan, and Guangxi will also experience heavy rains.

A separate report from the center showed that the rain intensified on Sept 19. The daily rainfall of 35 national monitoring stations in Shaanxi, Shanxi, Henan, and Hebei exceeded the historical records for September.

But by Sept 21, the Mid-Autumn Festival, most parts of the country will be sunny or cloudy except for light to moderate rain in the northeastern regions.

As this round of precipitation covers a wide range and has powerful intensity, it is necessary to be especially vigilant against secondary disasters, said the meteorologists.

Given that the rainfall coincides with the Mid-Autumn Festival holiday, they urge authorities to enhance management of traffic to reduce the adverse effects on urban operations and public travel.

The National Meteorological Center also renewed yellow alerts for gusts and gales from late night on Sept 19 to midday on Sept 20 for the Bohai Sea, the Bohai Strait, and parts of the Yellow Sea.
