Flooding is a temporary overflow of water onto land that is normally dry.
Floods are the most common natural disaster in the U.S., and one of the biggest threats for Williamson County.
- Result from rain, snow, coastal storms, storm surges and other water systems.
- Develop slowly or quickly.
- Cause power outages, disrupt transportation, damage buildings and create landslides.
Before a Flood
- Talk with your family about any areas around your home that flood frequently.
- Keep your emergency kit handy in case of evacuation, or in case you need stay home for a few days.
- Learn the safest evacuation routes from your home.
- Charge electronic devices if severe weather is expected, in case you lose power.
During a Flood
A flood can develop slowly over several days or within minutes, like a flash flood. You should know the difference between a flash flood watch and warning:
- Flash Flood Watch: Current or developing conditions are favorable for flash flooding the area.
- Flash Flood Warning: Flash flooding is in progress, about to happen, or highly likely.
In the event of a flash flood watch or warning, you should:
- Find a safe area right away!
- Have your emergency kit handy.
- If told to evacuate, follow your family’s evacuation plan.
- If floodwaters rise around your home move to a higher floor, but do not climb into a closed attic.
- If your home is not in danger but the roads are flooding, then stay home.
- Stay away from drainage ditches and culverts.
- Follow instructions. Listen to alerts and warnings, which are in place to keep you safe.
After a Flood
If you had to evacuate because of a flood, you may not be able to return right away. Right after a flood, emergency workers will have a lot to do to make sure it is safe before families can return to their homes. Once it is safe, the adults in your family may head back before kids in order to begin cleaning up.
Here are some important things to remember if you are in an area that has just flooded:
- Avoid floodwaters. Standing water can hide chemicals that can make you sick.
- Keep away from downed power lines, which can cause electrocution.
- Keep away from storm drains and culverts.
- Pay attention to those in charge for information and instructions.
Keep in contact with family and loved ones to let them know you are okay. If you are nervous or anxious, that's okay too! That is normal when big weather events happen. Talk to a family member or friend about how you feel.
