Satellite images and tracking maps of Tropical Storm Dianmu 2021, September 21 - 24. Max wind speed 65km/h.
Dianmu is expected to continue on its current track and make landfall south of Da Nang before 12 hours and transition across the rugged terrain of Vietnam and into Cambodia.
The marginal environment will likely maintain intensity while over water before beginning dissipation due to land interaction. Land interaction will erode the system to dissipation in 36 hours.
Numerical track models are in high agreement through the remainder of the forecast. Intensity guidance is in medium agreement due to competing environmental parameters.
Maximum significant wave height is 3.7 meters (12 feet).
