Matmo made landfall Wednesday night, local time, bringing with it heavy, tropical rainfall and possible flooding to southeastern Asia.
Tropical Storm Matmo developed early Wednesday morning, local time, after it moved over the open waters of the South China Sea on Tuesday. Warm ocean water, weak wind shear and little to no interaction with land helped the system to strengthen into a tropical storm.

While the mountains near the coast of Vietnam will work to tear apart and weaken Matmo, it can still bring dangerous flooding to the region.
With round after round of tropical downpours, widespread rainfall totals of 50 to 100 mm (2 to 4 inches) are expected.
In areas where the heaviest downpours occur, rainfall totals can reach 100 to 200 mm (4 to 8 inches). An AccuWeather Local StormMax™ of 300 mm (12 inches) is possible, especially in the higher elevations.
Through Thursday evening, local time, the city of Quang Ngai, south of Da Nang, reported 319 mm (12.56 inches) of rainfall from Matmo.
With this much rain expected in just a couple of days, flash flooding and mudslides will be a concern across much of the region.
Rain will spread farther west into Cambodia, eastern Thailand and Laos late in the day on Thursday and into Friday as the storm continues to dissipate. The heaviest rain will likely remain in Vietnam.
Winds began to increase along the coast of Vietnam on Wednesday and persisted on Thursday. Wind gusts reached 111 km/h (68 mph) in Quy Nhon.
According to CCTV Asia Pacific, approximately 1 million families in Binh Dinh, Quy Nhon and Phu Yen were without electricity.
Until Matmo moves inland and weakens, wind gusts will be able to reach between 65 and 97 km/h (40 to 60 mph). The highest gusts will be most likely to occur a the coast and near the center of the storm, especially on the northern side of the eye.
Wind gusts of this speed can bring localized damage and down some trees and power lines, especially given the saturated soil. Coastal flooding will also be a concern, especially in areas of the strongest onshore flow.
After a short break in the wake of the storm, spotty showers and thunderstorms will return to Vietnam through the end of the week as recovery efforts begin.
