Quick Answer
High ground is not always the safest option during a flood. In some cases, it can even be more hazardous, especially in urban areas with stormwater drainage systems.
Understanding Flood Dynamics
When a flood occurs, water can rise rapidly, often exceeding 6 inches per minute in the first hour. This swift water can sweep away vehicles, buildings, and people. In flash floods, the water level can increase by 10-15 feet in a matter of minutes, making it difficult to escape to high ground. In these situations, it’s essential to prioritize escape routes over elevation.
Vehicle Safety in Floods
If you’re driving, never attempt to cross a flooded road. Water can hide obstacles, such as potholes, fallen power lines, or even entire vehicles. A mere 6 inches of water can cause a vehicle to lose traction, while 12-18 inches can sweep it away. If you’re swept away by floodwaters, your chances of survival decrease significantly after 30 seconds.
Assessing the Surroundings
When assessing your surroundings during a flood, look for signs of rapidly rising water, such as changing water levels, erosion, or loud rushing sounds. These indicators can signal an impending flash flood. Avoid areas with standing water, as they can conceal hidden dangers like sinkholes or structural damage. Stay informed through local news and weather reports, and follow evacuation orders promptly.
