Continued heavy rainfall from Tropical Storm Gaemi triggered a landslide that killed 12 people in southern China, caused flash floods in the northeast and railway disruptions elsewhere, state media reported on Sunday.

Cyclonic winds from Gaemi, downgraded from a typhoon, had mostly dissipated by Sunday, but many parts of China remained under alert for flooding risks caused by earlier rain. Remnants of Gaemi’s vast cloud-banks could still dump rain on already waterlogged cities, forecasters warned.

The 12 were killed in the landslide near Hengyang city in Hunan province on Sunday morning that trapped 18, state broadcaster CCTV reported. Six injured survivors were rescued. Hunan provincial authorities issued a flood warning as heavy rain continued through Sunday.

Two officials, including the deputy mayor of Linjiang city in Jilin province, were reported missing during flood rescue efforts, CCTV said, citing city authorities. More than 27,000 people in northeast China were evacuated and hundreds of factories suspended operations.

The most powerful storm to hit the country this year lashed towns on coastal Fujian province on Friday with heavy rain and strong winds as it began its trek from the southeastern coast into the populous interior.

Jilin province, bordering North Korea, issued upgraded warnings for heavy rains and flash floods on Sunday morning.
