Typhoon Matmo struck the coast on the coastal regions of China on Sunday afternoon, shortly after passage over the island province of Hainan.

Ferry services were halted and flights cancelled at the airport in Haikou.

Storm Details

The typhoon, this year's 21st cyclone of 2025, had sustained wind speeds of 94mph and poured over 50mm of rainfall in six hours in Qinzhou and Chongzou. Urban areas of the region also experienced high rainfall totals.

The storm prompted China's top-tier red alert, with disturbances in the city, where commercial activities, transport links and highways were shut. In the special administrative region, numerous air services were affected and dozens called off.
