At 10.00am the storm was swirling around the central coast from Da Nang to Quang Ngai, weakening into a tropical low depression with winds gusting 50kph near its centre.
In the next 3 to 12 hours, Conson is forecast to move slowly at a speed of 5kph and weaken further into a low depression.
Though Conson is yet to batter the region, its strong winds and heavy rain have over the past hours caused consideration damage to coastal localities.
In Quang Ngai, two fishing boats and a barge tugboat sank at the height of sea surges. A total of 18 people on board these boats were luckily rescued by the local coastguard force.
Strong winds damaged or tore roofs off 23 houses in Thua Thien-Hue and Kon Tum provinces. More than 1,000ha of rice and subsidiary crops in Quang Binh, Quang Tri and Kon Tum were submerged.
Heavy rain triggered landslides, disrupting traffic flows on National Highway No24 and several provincial and inter-commune roads in Kon Tum. Rising floodwaters washed away a woman in Tu Mo Rong district. Her dead body was retrieved hours later.
Local authorities of Quang Ngai evacuated hundreds of residents out of low-lying areas at risk of flooding in Tra Bong, Ba To and Binh Son districts.
Weather forecasters say widespread rainfall of 100-200mm is possible over much of the central region. Higher amounts are likely in localities from Da Nang to Quang Ngai.
