Tropical Cyclone Matmo Struck Coastal China Bringing Massive Relocations

The powerful storm struck the coast on the southern shores of China on Sunday afternoon, shortly after passage over the island province of Hainan. The intense weather led to the relocation of approximately 350,000 people, bringing torrential rain and damaging winds, particularly between Wuchuan in Guangdong and Wenchang in Hainan. Ferry services were suspended and flights cancelled at Haikou Meilan airport.

Typhoon Statistics

The typhoon, the 21st typhoon of 2025, recorded wind speeds of 94mph and dumped more than 50mm of rainfall in six hours in Qinzhou and Chongzou. Urban areas of Nanning also received high rainfall totals.

The storm triggered China's top-tier red alert, with disturbances in the city, where commercial activities, transport links and roads were shut. In Hong Kong, numerous air services were affected and 30 cancelled.

Future Projections

As Matmo moves inland towards the provincial area in Vietnam, it is projected to weaken into a less intense system with 89km/h winds but will continue to bring substantial precipitation. Northern Vietnam could face 130-150mm on Monday, raising the risk of flooding and landslides. The system is anticipated to move towards Yunnan region in China, where additional intense rain is probable.

Other Storm Systems

At the same time, a hurricane named Priscilla formed off the Pacific shoreline of Mexico on Saturday night, first as a storm system. It prompted a storm watch for the southwestern areas from Punta San Telmo to Punta Mita on the start of the week.

In the early hours of Sunday, the hurricane was about 491 kilometers from Cabo Corrientes with sustained winds of 65mph. It intensified into a severe cyclone in the evening, when sustained winds peaked at 75mph.

Although unlikely to hit the coast, the storm is expected to produce dangerous waves and strong currents as it moves northwestward along the coast towards Baja California Sur. Heavy rainfall is forecast on the coming day, reaching 100-150mm in specific Mexican states, with some areas at about 200mm. Other regions could receive moderate to heavy rain.

Elsewhere, a cyclone named Shakhti has formed as the first post-monsoon cyclonic storm of 2025 in the Arabian Sea, causing an warning from the national weather agency for Maharashtra. On that day, the cyclone was 209 kilometers southeast of a location in Oman with peak wind speeds of 103km/h.

Shakhti, which has moved south-westward and lost strength, is forecast to recurve towards the east into the Arabian Sea. Rough seas are likely to persist along the coastal stretch and heavy rainfall is anticipated in coastal districts including Dwarka, Jamnagar and Surat.
