The death toll from record-breaking rains across northern China has risen to at least 78, as authorities warned of more flooding and another storm has approached the country.

Fatalities from flooding in Hebei province surged to 29, as reported by state media on Friday.

Typhoon Doksuri, which struck mainland China as a typhoon a fortnight ago, triggered the most extreme rainfall on record in 140 years.

Rescuers have continued to search for people swept away by the floods, as another storm, Khanun, approaches over the weekend.

The deluge followed weeks of historic heat, with scientists saying such extreme weather events are being exacerbated by climate crisis.

Streets in parts of Hebei, which borders Beijing, were still caked in mud on Wednesday. Residents were scrambling to recover waterlogged belongings and clean up damaged homes.

During a visit to affected communities last week, Hebei province party chief Ni Yuefeng said that the area could "reduce the pressure on Beijing's flood control" and serve as a "moat" for the capital.

As of Thursday, 29 people had been killed by the rains across the province, six of whom had been previously listed as missing, state broadcaster CCTV said Friday. Sixteen are still missing.

In Beijing, at least 33 people have died, including two rescue workers, authorities said this week and more than a dozen people were killed in northeastern Jilin province after torrential rain last week.

In the neighbouring Liaoning province, two deaths were reported after the first few days of intense rain in late July.

On Friday, state news agency Xinhua said that another flood control team had been sent to the province, where "the local flooding situation remains severe".

Heavy rains are expected again over the weekend as tropical depression Khanun – formerly a typhoon – approaches China.

Emergency alert levels are being held in place across northern China, Xinhua said, with key riverways being closely monitored.

Heavy damage

China's state media has hailed the government's efforts to mitigate damage from the inundations, with coverage focused on tales of mutual aid and selfless officials working tirelessly on rescue efforts.

But a week after the waters first swelled, some villagers in Hebei said they did not receive adequate warning from the authorities about when the floods would come.

The Chinese government on Wednesday said it would allocate one billion yuan ($139 million) to compensate residents in areas that had been inundated to control flood levels in downstream areas.

The fund would pay for "damage to crops, animal and poultry farms, commercial forests, houses and agricultural machinery", according to Xinhua.

Solely in Hebei, authorities stated that nearly four million individuals faced the impact of the floods, resulting in 40,900 homes collapsing, as per local reports.

Hundreds of thousands of hectares of crops have been damaged in the province. According to Xinhua insurance providers in Beijing are paying out at least 380 million yuan in claims for losses caused by the recent rains.

The bad weather is not limited to northern China. The State Flood Control and Drought Relief Headquarters reported the possibility of heavy weekend rain in Sichuan, Yunnan, Gansu, and Qinghai provinces.

Seven people lost their lives in a sudden flash flood near Chengdu, Sichuan. The incident occurred as an unanticipated surge of water swept away tourists along the Longxi River. And in Gansu, five people were killed when they were swept away by mountain torrents after a rainstorm alert on Thursday, Xinhua added.
