Quick Answer
If caught in a flash flood, move immediately to high ground, avoid low-lying areas, and avoid walking or driving through floodwaters. Stay away from bridges and culverts, as these can be swept away or collapse. If in a vehicle, abandon it and seek higher ground.
Assessing the Situation
When caught in a flash flood, assess the situation quickly. Check for hazards such as fallen power lines, sharp debris, and steep drop-offs. If you are in a vehicle, do not try to drive through the floodwaters. Water can be deeper and faster-moving than it appears. If you are on foot, move away from the water’s edge and find higher ground.
Seeking High Ground
Flash floods can sweep away buildings and infrastructure in seconds. Move immediately to high ground, which is typically at least six feet above the surrounding terrain. Look for natural high points, such as hills, ridges, or rock outcroppings. Avoid areas with standing water or where water is flowing rapidly. If you are in a valley or low-lying area, move to the sides or up-slope.
Vehicle and Water Safety
If you become trapped in a vehicle in flash floodwaters, abandon it and seek higher ground. Do not try to drive through the water or wait for the water to recede. Water can rise quickly, and currents can be powerful. If you cannot escape the vehicle, stay inside and call for help. If you are on foot, avoid walking through floodwaters, as the current can be strong and the water may be contaminated. If you must wade through the water, use a flotation device or a long branch to help you stay afloat.
