Le Dinh Quyet, a meteorologist from the Southern Hydrometeorological Center, told VnExpress that the storm weakened at 11.20 a.m. after making landfall in Vung Tau. The tropical low has moved over the nearby Can Gio coastal district in Ho Chi Minh City. Southern provinces including Ba Ria-Vung Tua, Long An, Tien Giang, Ben Tre, Tra Vinh and Ho Chi Minh City will be battered by heavy downpours of up to 180 millimeters until Sunday night, Quyet said. Storm Usagi comes a week after heavy rains from Typhoon Toraji triggered landslides that killed at least 20 people in the south central resort town Nha Trang. Weather forecasters in Vietnam have warned another four to six typhoons and tropical depressions could develop off the country’s east coast from now until the end of the year. Half of them would make landfall in and batter Vietnam’s central region, they said. A record number of 16 tropical storms hit Vietnam last year, killing 389 people and injuring 668 others, mostly in the northern and central regions. The General Statistics Office estimated damage at around VND60 trillion ($2.64 billion), 1.5 times the previous year’s figure. In the first 10 months of this year natural disasters left 185 people dead or missing and injured 134 others, and caused losses of more than VND8.8 trillion ($381 million).
