Typhoon Statistics

Matmo, the 21st cyclone of the year, had sustained wind speeds of 151km/h and dumped more than 50mm of precipitation in a short period in Qinzhou and Chongzou. Urban areas of the region also experienced significant rain amounts.

Matmo triggered China's highest-level emergency warning, with disturbances in Zhanjiang, where commercial activities, transportation systems and roads were closed. In the special administrative region, 100 flights were affected and 30 cancelled.

As Matmo 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 substantial precipitation. Vietnam's northern regions could face 130-150mm on the following day, increasing the threat of flooding and landslides. The weather pattern is anticipated to move towards Yunnan province in China, where further intense rain is probable.
