When flood warnings flash across your phone, it’s already too late to scramble for supplies. Unlike hurricanes that give days of warning, flash floods can develop in as little as an hour, turning neighborhood streets into rushing rivers and basements into dangerous traps.
Flooding is one of the most common natural disasters in the U.S., and the second leading weather killer (only behind heat).
Critical Flood Safety Rules
Before and after a flood, there are a few critical safety rules to keep in mind. Find shelter right away at the first alert warning, staying off bridges and avoiding fast-moving water.
- Evacuate immediately if possible: It sounds simple, but if you have a chance to evacuate, leave before the roads flood.
- If trapped at home: Move to the highest floor, but never into an enclosed attic.
- Never walk in moving water: Six inches of moving water can knock you down.
- Avoid electrical hazards: Stay away from downed power lines.
- Water contamination: Assume all flood water is contaminated.
- Use generators outdoors and away from windows: Generators can produce significant amounts of carbon dioxide.
