The powerful storm struck the coast on the coastal regions of China on Sunday afternoon, following its passage over the island province of Hainan.

Storm Details

Matmo, the 21st cyclone of 2025, had sustained wind speeds of 151km/h and dumped more than 50mm of rainfall in six hours in Chongzou and Qinzhou. Urban areas of Nanning also experienced high rainfall totals.

Matmo triggered China's top-tier emergency warning, with disturbances in the city, where commercial activities, transportation systems and roads were shut. In Hong Kong, numerous air services were impacted and 30 cancelled.

Future Projections

Vietnam's northern regions could face 130-150mm on the following day, raising the risk of flooding and landslides. The system is anticipated to move towards Yunnan region in China, where further intense rain is probable.
