(TWN)-According to local meteorologists, the worst rainfall in 140 years triggered severe flooding in Beijing, and the region faces little respite as Typhoon Khanun batters Japan with wind and rain.

According to the Beijing Meteorological Service, 744.8 millimeters (29 inches) of rain poured in the Chinese capital from the remnants of Typhoon Doksuri between Saturday and Wednesday morning, the greatest rain over consecutive days since records began in 1883.

Meanwhile, Typhoon Khanun made its closest approach to Japan's southern Okinawa islands early Wednesday, packing gusts of 220 kilometers per hour (137 mph), the equivalent of a Category 4 Atlantic hurricane.

Various areas in Okinawa have received 175 to 220 millimeters (6 to 8 inches) of rainfall in the last 24 hours.

Strong winds knocked out power lines, leaving over 200,000 houses without electricity on Wednesday morning, and the prefecture government ordered over 600,000 inhabitants to leave their homes, according to Okinawa Electric Power Company.

In the next 48 hours, it is predicted that Khanun's core would stall in the East China Sea. During the course of the weekend, it may veer toward Japan's northern Ryukyu Islands, avoiding direct damage to China's eastern shore, which has been inundated by Doksuri's remnants.

The slow-moving Khanun is gradually losing strength, but in the next days, its outer bands may deliver strong winds and a lot of rain to China's eastern Zhejiang province and the coast near Shanghai.

The impact of Khanun follows that of Doksuri, which caused floods to overwhelm Beijing's western suburbs, destroying a bridge and washing away automobiles.

Twelve people have died in Beijing, according to Beijing Daily, the official Chinese media, while another twelve are still unaccounted for. More than 127,000 individuals were taken out of the city, according to state broadcaster CCTV.

According to CCTV, nine deaths were also recorded in the capital's surrounding province, Hebei. 10 meteorological stations reported record-breaking amounts of rainfall in Hebei, according to state-run news agency Xinhua.

According to state-run publication The Paper, over 300 people were left stranded in a residential building in Zhuozhou city, Hebei, on Tuesday.

According to a woman cited in the story, the tenants of the building had "no drinking water, no electricity, and no gas," and video revealed that floodwaters had seeped into the basement.

The downpour in Zhuozhou city has affected around 133,900 people, as reported by CCTV.

While significant downpours were warned for many northeastern provinces, including Jilin, Heilongjiang, and Inner Mongolia, Xinhua reported that rain was likely to lessen in Beijing and Hebei on Wednesday.

The leader of China, Xi Jinping, has instructed officials to reduce losses and quickly return living conditions to normal while also demanding extensive search and rescue operations.

The majority of the data is gathered over the internet.
