Flash floods pose significant risks to everyone, regardless of swimming ability. Even shallow-looking water can carry vehicles, debris, and other hazards, increasing the risk of drowning. Children are particularly vulnerable, as they may not recognize the dangers of high water or storm drains. Drivers are at risk of being swept away if they attempt to cross flooded roads, and pedestrians face similar dangers when wading into floodwaters. The NWS stresses that no one can reliably judge the depth, speed, or hidden dangers of floodwaters, making it crucial to avoid them entirely.
