Zhang Linna, chief forecaster at Beijing Meteorological Service, said current conditions in the capital are favorable for more strong rain.

"Beijing has been affected by unstable convection, with high temperature and high humidity, which can easily result in severe convection featuring brief strong rainfall," said Zhang.

She also said warm air in the southwestern part of the subtropical high has been contributing abundant water vapor to the capital.

From Monday afternoon to Wednesday, Beijing will see more rain. On Tuesday, most areas in the capital are expected to receive rainfall of 30 to 40 millimeters. Hourly precipitation may be as high as 50 millimeters, she said.

On Monday, rescuers continued safety measures following a landslide of 5 million cubic meters of soil and rock on Thursday in Nanyu township, Gansu province. About 10,000 cubic meters of the debris entered the Bailong River, partly blocking the river and increasing the water level by about 7 meters.

More than 400 tents were set up in case more of the debris entered to block the river and flood nearby homes, local authorities said. But they noted that the water level had subsided.
