The powerful storm struck the coast on the southern shores of China on Sunday afternoon, shortly after sweeping across the island province of Hainan.

Typhoon Statistics

The typhoon, the 21st typhoon of 2025, recorded wind speeds of 151km/h and poured more than 50mm of precipitation in six hours in Chongzou and Qinzhou. The city of Nanning also received significant rain amounts.

Matmo triggered China's highest-level red alert, with disruptions in Zhanjiang, where commercial activities, transportation systems and highways were closed. In Hong Kong, numerous air services were impacted and dozens called off.

Forecast and Movement

As the typhoon advances inward towards Cao Bang province in Vietnam, it is projected to diminish into a less intense system with 89km/h winds but will persist to bring heavy rainfall. Northern Vietnam could face significant rainfall on the following day, raising the risk of flooding and mudslides. The weather pattern is expected to move towards Yunnan province in China, where additional heavy rainfall is probable.

Other Storm Systems

Meanwhile, Hurricane Priscilla developed off Mexico's Pacific coast on the weekend, initially as a storm system. It led to a weather alert for south-western regions from Punta San Telmo to another location on the start of the week.

In the morning of the next day, Priscilla was about 305 miles from a Mexican cape with continuous gusts of 65mph. It strengthened into a severe cyclone in the night, when wind speeds peaked at 75mph.

Although unlikely to hit the coast, the storm is likely to produce hazardous swells and strong currents as it moves northwestward along the coast towards a Mexican state. Heavy rainfall is predicted on the coming day, amounting to a considerable volume in specific Mexican states, with some areas at about 20 centimeters. Other regions could face 50-100mm.

Elsewhere, Cyclone Shakhti has formed as the first post-monsoon cyclonic storm of 2025 in the a body of water, prompting an warning from the India Meteorological Department for an Indian state. On that day, the cyclone was 209 kilometers southeast of a location in Oman with peak wind speeds of 64mph.

Shakhti, which has moved south-westward and lost strength, is forecast to turn towards the east into the Arabian Sea. Turbulent waters are expected to persist along the coastal stretch and heavy rainfall is expected in shoreline areas including specific Indian cities.
