The rapid development of Typhoon CHANTHU from the light station will become a strong station. The 3th River Management,WRA has cooperated to complete various flood prevention preparations as soon as possible, and cooperated with the Taichung and Nantou county governments to confirm the key points of the previous Typhoon Lubi disaster and prevent it from letting go. After a second disaster occurs, we will continue to use smart flood prevention technology to monitor the safety of structures and prevent flooding, and we will deploy ahead of schedule.
