Beijing is preparing for an intense spell of rain that could deliver more than one-third of the Chinese capital's average annual rainfall within 24 hours, raising the risk of flooding across densely populated districts.

More than 150mm forecast in 24 hours

The city's meteorological service said most areas would experience heavy downpours from Tuesday evening through Thursday. Rainfall could exceed 100mm within six hours and reach more than 150mm over 24 hours.

Some districts could receive more than 200mm in a single day, including Tongzhou, Daxing, Fangshan, Mentougou, Huairou and Fengtai. Beijing's average annual rainfall is about 528mm, with most normally falling between June and September.

Highest flood alert issued in Mentougou

Authorities in the mountainous western district of Mentougou issued the highest level of flood emergency alert on Tuesday. Residents were advised to stay indoors unless necessary and to avoid mountainous areas and rivers.

The rainfall threat developed as moisture associated with Typhoon Dolphin to the south converged with cooler air over northern China. The combination is expected to produce concentrated downpours capable of overwhelming drainage and rapidly raising water levels.

What it means for foreigners in Beijing

Foreign residents and visitors should monitor official weather and transport notices, avoid rivers, mountain routes and low-lying areas, and allow extra time for disrupted journeys. Do not attempt to walk or drive through floodwater. Travellers with flights or rail connections should check directly with their operator before leaving, while anyone in an affected district should follow local emergency instructions and remain indoors when advised.
