Floodwaters rise due to heavy rainfall in the northern mountain regions, issuing warnings for potential flash floods and landslides.
Heavy Rain and Flood Warnings Sweep Across Vietnam
Vietnam is bracing for severe weather conditions as heavy rain and flash flood warnings affect multiple provinces across the northern, north-central, Central Highlands, and southern regions from mid to late August 2025. The rainfall amounts vary by region, with some areas receiving over 300 mm in 24 hours.
In the northeastern provinces, such as Quang Ninh and Hai Phong, rainfall is expected to range between 50–150 mm, with localized areas exceeding 300 mm within 24 hours. The north-central provinces, including Thanh Hoa, Nghe An, Ha Tinh, and Quang Tri, are expected to receive rainfall ranging from 20 to over 250 mm. Thanh Hoa and Nghe An are forecasted to receive 60–130 mm generally, with local areas exceeding 250 mm.
The Central Highlands and southern regions are predicted to receive 50–100 mm generally, with some spots exceeding 200 mm. Coastal and sea areas are experiencing strong winds, waves 2-3 meters high, rough seas, and hazardous maritime conditions.
Risk levels and warnings indicate that flash floods on small rivers and streams and landslides on hillslopes are expected in many communes and wards in 13 provinces. The disaster risk for tornadoes, lightning, and hail is rated Level 1, indicating some threat though not at highest severity.
Residents are urged to follow official forecasts and warnings to prepare for flash floods, landslides, and potential tornadoes from now until the end of August 2025. All vessels in these areas are at risk from severe weather, and authorities warn that events could threaten lives, disrupt traffic, and damage infrastructure and production.
The affected areas include the Trường Sa (Spratly Islands), Lâm Đồng to An Giang, and the Gulf of Thailand. Forecasters expect rain and thunderstorms throughout Monday in the northern and southern East Sea, northern Gulf of Tonkin, waters from Lâm Đồng to Cà Mau, from Cà Mau to An Giang, and the Gulf of Thailand. Thunderstorms may bring whirlwinds at sea, strong gusts, and waves up to 3 meters.
Local agencies are urged to inspect vulnerable areas and take preventive measures. Scattered showers and thunderstorms are affecting the southern East Sea (South China Sea). Officials are closely monitoring the situation as tropical convergence zones and low-pressure systems potentially intensify severe weather, including a tropical depression and remnants from Tropical Cyclone Wipha.
| Region / Provinces | Rainfall Amounts | Risk Level / Hazards | |--------------------------------|---------------------------------|---------------------------------------------------| | Northeastern (Quang Ninh, Hai Phong) | 50–150 mm, some >300 mm in 24h | Flash floods, heavy rain, strong winds up to 49 kph | | North-central (Thanh Hoa, Nghe An, Ha Tinh, Quang Tri) | 20 – 250+ mm, locally heavy | Flash floods, landslides, Level 1 tornado/lightning risk | | Central Highlands & South | 50–100 mm, some areas >200 mm | Flash floods, landslides | | Coastal waters (Khanh Hoa to Ca Mau, Gulf of Tonkin) | Rough seas, waves 2-3m (occasionally >3m) | Strong winds, hazardous navigation |
- Amidst intensifying weather conditions in 2025, Vietnam's Central AI systems are being utilized to predict and manage the water levels in vulnerable areas, aiming to minimize damages caused by flash floods and landslides.
- In the face of the environmental-science challenges posed by severe weather, scientists are working tirelessly to forecast and model potential impacts on the country's vulnerable terrains, offering preventive measures against war-like destruction resulting from the floods.
- As Vietnam grapples with the wrath of nature, the government is issuing AI-based alerts to inform residents in affected provinces about potential weather hazards, urging them to prioritize safety over their daily activities until the end of August.
