Thái Bình Province
On August 15, a tropical depression developed about to the southeast of Hong Kong. During the course of August 17, enhanced satellite imagery showed that Dianmu was rapidly organizing with deep flaring convection surrounding its LLCC. Dianmu made landfall in Haiphong and Thái Bình Province in northern Vietnam. While overland, the system gradually weakened into a tropical depression, before it degenerated into an area of low pressure during August 20 while over Myanmar.
