Vietnam - November 24, 2025 A video filmed by X user Thanh Tuong shows heavy flash flooding on National Highway 51 in Dong Nai province during a nighttime rainstorm. The footage reveals a dark urban stretch of road where fast-moving muddy floodwater covers the asphalt, with depths ranging from several inches to about a foot. The scene is lit only by vehicle headlights, streetlights, and a red traffic signal, while heavy rain and darkness sharply limit visibility as water splashes and ripples across the frame. Traffic is engulfed in chaos as multiple vehicles try to move through the flooded highway, including cars, trucks, and motorcycles. A black sedan appears partly stalled or parked with its wheels submerged, while some drivers seem to be forcing or pushing their vehicles through the current, their headlights cutting sharply through the spray. Around the road, details of the surroundings emerge through the downpour. Road signs, including a triangular warning sign, roadside barriers, palm trees, and distant buildings or gates are partially visible. No pedestrians can be clearly seen in the clip, which keeps its focus on the dangerous driving conditions created by the sudden flash flooding.
