Flood levels and safety

Most flood deaths in the US happen in vehicles. Six inches of fast water can knock an adult off their feet, and a foot or two can float a car. If a road is covered, turn around.

Readings can change quickly after heavy rain upstream, so check again before heading near the water.

How we check values

Each reading is stored as published. We hold back values that jump faster than physically plausible and show the measurement time with every value.
