Staying Safe During Floods

Flood Safety

Flooding is one of the most common and costly natural disasters – and it can happen anywhere. Whether it is caused by overflowing rivers, heavy rainfall, or rapid snowmelt, even a few inches of water can cause significant damage to homes and pose serious risks to lives.

Idaho Office of Emergency Management (IOEM) encourages all Idahoans to take proactive steps to protect themselves, their loved ones, and their property before, during, and after a flood.

Before a Flood

Floods can develop gradually or strike without warning. Flash floods are especially dangerous due to their sudden onset and swift-moving waters. Being prepared can save your life and give you peace of mind.

  • Know Your Risk: Check local flood maps and stay informed about flood-prone areas in your community.
  • Sign Up for Alerts: Stay informed with flood watches and warnings from the National Weather Service (NWS). Sign up for emergency alerts through the Integrated Public Alert & Warning System (IPAWS), Idaho State Alert and Warning System (ISAWS), and Wireless Emergency Alerts (WEA). Follow local emergency management agencies and NWS on social media for real-time updates. Be sure to also tune into and the National Oceanic and Atmospheric Administration (NOAA) Weather Radio
  • Have an Emergency Plan: Make sure your household has a plan in place, including evacuation routes and a communication strategy.
  • Prepare an Emergency Kit: Stock up on essentials such as non-perishable food, water, medications, flashlights, batteries, and important documents in a waterproof container.
  • Protect Your Home: Elevate electrical appliances and store valuables in waterproof containers to minimize flood damage.
  • Purchase Flood Insurance: Standard homeowner’s insurance typically does not cover flood damage. Protect your property by investing in a policy through the National Flood Insurance Program (NFIP).

Knowing the difference between the different flood alerts issued by NWS can help you take appropriate action when necessary.

  • Flood Advisory: Flooding is possible but not expected to be severe. While it may cause inconvenience, caution is still advised to prevent potential threats to life and property.
  • Flood Watch: Conditions are favorable for flooding. Stay alert, monitor weather updates, and be ready to act if conditions worsen.
  • Flood Warning: Flooding is either occurring or imminent. Take immediate precautions, move to higher ground if necessary, and follow official instructions.
  • Flash Flood Warning: A flash flood is imminent or already occurring. If you are in a flood-prone area, move immediately to higher ground. Flash floods develop rapidly, often within minutes or hours.
During a Flood

Floodwaters can rise quickly and create dangerous conditions. Knowing what to do during a flood can help keep you safe.

  • Follow evacuation orders: Listen to instructions from local authorities and emergency responders.
  • Find Higher Ground: If flooding is imminent, move to higher ground immediately. If evacuation orders are issued, follow them without delay.
  • Turn Around, Don’t Drown: Never walk, swim, or drive through floodwaters. Just six inches of moving water can knock you off your feet, and one foot of water can carry away a vehicle.
  • Avoid Bridges Over Fast-Moving Water: Floodwaters can quickly erode bridge foundations, making them unstable and dangerous.
  • Stay informed: Tune into emergency broadcasts and weather updates whether that is through NOAA Weather Radio, or local alerting systems.
  • Electrical Safety: If water is rising inside your home, turn off electricity at the breaker but only if it is safe to do so. Never enter any room or basement where water is covering electrical outlets or submerging cords.
After a Flood

Floodwaters can leave behind devastation and hidden dangers. Taking precautions after a flood can help keep you safe.

  • Wait for All Clear: You are encouraged not to return home until local authorities say it is safe.
  • Listen to Road Closures and Cautionary Signs: Road closure and other cautionary signs are put in place for your safety. Pay attention to them!
  • Avoid Contaminated Water: Floodwaters can be contaminated with chemicals, sewage, and debris. Stay out of standing water to prevent illness and injury.
  • Inspect with Caution: Check for structural damage before entering buildings. If you smell gas, see electrical hazards, or suspect damage, leave immediately and contact emergency services.
  • Clean Up Safely: Wear protective gear like gloves and boots when cleaning up flood damage. Disinfect surfaces to prevent mold and bacteria growth.
  • Help Your Community: The road to recovery after a flood is a collective effort. Checking in on neighbors and supporting local relief efforts can make a significant difference.

By knowing your risk, creating a plan, and staying informed, you can protect yourself and your loved ones. Floods can happen quickly, but being prepared ahead of time helps make sure you stay safe during and after the storm.
