Dong Nai typhoon guide

Dong Nai, in southern Vietnam, now includes the former Bình Phước province, which was merged into it on 1 July 2025 under National Assembly Resolution 202/2025/QH15. The province is inland and is not hit by the sea, so typhoon effects are mostly heavy rain, flooding, flash floods, landslides, strong squalls, and flood releases from hydropower reservoirs on the Đồng Nai, La Ngà, and Sông Bé rivers. The Ban Chỉ huy Phòng thủ dân sự (Civil Defense Command) directs the response, and the Đài Khí tượng Thủy văn tỉnh Đồng Nai (Dong Nai provincial hydro-meteorological station) gives local forecasts. Official storm and flood notices are published in Vietnamese.

Evacuation centers

Open only when announced

Evacuation centers open only when officials announce them, and not every center opens for every storm. Check the official list of open centers before you leave home. Bring your own bedding, food, water, and medicines.

No standing list of shelters or evacuation sites was confirmed for this page. Evacuation is organized by the commune and ward People's Committees and the provincial Civil Defense Command under the "4 on the spot" principle (4 tại chỗ), which provincial directives repeat. Follow your commune or ward authorities and the provincial Civil Defense Command for whether to move and where to go.

Radio, TV and weather

Keep a battery or hand crank radio. When power and cell service fail, radio is often the only way to hear official updates.
