About 130,000 people have been evacuated from the Guangxi region while thousands of rescuers have been deployed.

Flooding from Tropical Storm Maysak has killed 39 people in southern China, most of them after a dam breach inundated the city of Nanning.

Ding Wei, the city’s vice mayor, announced the toll at a news briefing on Thursday, up sharply from a previous count of six, after record rainfall breached reservoirs and sent torrents of water through towns and cities in the Guangxi region.

The dam breach in Nanning killed 26 people, Ding said.

About 130,000 people have been evacuated from the region, and drones and thousands of boats have been used in a huge relief and rescue operation to reach people trapped by the waters.

Heavy rain battered southern Guangxi for days, with cumulative rainfall of 10-40cm (4-16in) in some areas and more than 90cm (35in) in hard-hit areas, the national meteorological centre said.

More than 8,000 people and about 5,700 boats have been deployed in the rescue operation, with rescuers battling strong currents and debris to reach victims.

Ding said the floodwaters are receding, but more rain is expected in certain areas in the next two days.

Crews have been deployed to clear mud and debris and disinfect several towns in hard-hit Hengzhou city, which is east of Nanning and under its jurisdiction.

Road repairs are ongoing, and electricity has been restored to more than 60,000 homes, Ding said.

Animals escape after flooding hits zoo

At least 100 animals, including alpacas, miniature pigs and zebras, escaped Guangxi province’s Guigang Zoo after the flooding damaged their enclosures.

The zoo appealed to the public Wednesday for help in finding its escaped animals.

The missing creatures include “two North American raccoons, four porcupines and thirty peacocks”, according to a statement posted by a local district’s Culture, Sports and Tourism Bureau.

The zoo said some of the escapees “may be frightened and potentially aggressive”.

“If you spot any of the animals, please keep a safe distance,” the statement said.

“Do not attempt to catch, approach or tease them, as this could be dangerous,” the zoo warned.
