BEIJING — The death toll from devastating storms in parts of China rose to 15 today, with hundreds more injured and tens of thousands evacuated, state media reported, as President Xi Jinping urged “all out” rescue efforts.

Dramatic video shared by state broadcaster CCTV showed a torrent of muddy water rushing past the crumbled concrete walls of a reservoir dam that had burst in the southern region of Guangxi.

Rescue workers wearing life vests and helmets searched for missing people, while others were deployed on inflatable boats, state media footage showed.

Thunderstorms and gale-force winds killed at least 11 people and injured 331 in the central province of Hubei, and tornadoes were reported elsewhere late yesterday, state news agency Xinhua said.

In Guangxi, heavy rains and severe flooding from Typhoon Maysak killed at least four people. At least 50,000 people were evacuated but eight were still missing.

Videos of villagers frantically trying to catch snakes swimming in a flooded Guangxi town went viral on social media, with a related hashtag racking up over 180 million views.

Around 800 to 900 snakes escaped yesterday morning after a breeding farm was washed away, Wu Zhi, the head of a local village committee, told state-owned media Red Star News.

Photos showed villagers wading through knee-deep water and using nets and their bare hands to capture the slithering reptiles.
