Typhoon Koto – Situation Update (28 November 2025)
Typhoon Koto continues to weaken as it moves slowly across the central East Sea. Forecasts indicate a possible approach toward Gia Lai Province around 1–2 December, most likely as a tropical storm. While the system is losing strength, some coastal effects are still expected over the coming days.
Key Points to Note:
• Sea conditions: Rough seas forecast between Da Nang and Nha Trang from 28–30 November, which may temporarily affect boat operations and island excursions.
• Tourism operations: All major destinations — Hội An, Da Nang, Quy Nhon, Nha Trang — remain open and functioning normally.
• On-ground monitoring: Local authorities and ASEV ground teams are closely following developments, especially in areas affected by early-November flooding.
• Forecast outlook: System likely to weaken further before nearing the South Central Highlands around 1–2 December.
ASEV Travel will continue to issue timely updates as needed.
Why Vietnam Faces Seasonal Flooding
Central Vietnam, particularly Hue and Hoi An, has recently been affected by renewed flooding caused by prolonged heavy rainfall and water released from certain dams after several days of intense precipitation. While some images circulating internationally may appear striking due to the very real flooding observed in certain areas of Central Vietnam, these phenomena nonetheless occur during the rainy (monsoon) season, and 2025 has proven to be an especially intense year in terms of rainfall.
Seasonal flooding in Central Vietnam is not unusual — it is a recurring climatic pattern between September and December. However, 2025 has registered exceptionally high rainfall, with some districts recording 1,000–2,000 mm in just a few days.
Key contributing factors:
- Steep mountain-to-coast topography
- Short, reactive river systems
- Water released from dams during prolonged rainfall
- Reduced vegetation & deforestation
Combined, these factors lead to temporary and localized flooding, managed through established protocols by local authorities and tourism professionals.
Latest Meteorological Data – Updated Context
Recent official reports confirm that several rivers across Central Vietnam have reached — and in some cases exceeded — historic flood levels, affecting a corridor from Quang Tri to Khanh Hoa, including Phu Yen, Dak Lak, and Khanh Hoa, among the most heavily impacted provinces. This situation results from high rainfalls in just a few days, saturating soil, river basins, and dams. Authorities also warn that risks of flash floods, sudden river rises, and landslides may continue in mountainous or downstream areas. We confirm that ASEV Travel currently has no groups travelling in these potentially affected zones.
