The Tornado Strikes
On March 27, 2023, Huntsville, Alabama, experienced a devastating EF3 tornado. You were in your basement shelter when the tornado hit. The basement was 12 feet below ground level, with 18-inch thick concrete walls and a 12-inch thick concrete floor. The tornado was visible through the basement window, with a funnel cloud just 100 yards away. You heard the tornado approaching 10 minutes before impact, with a sound like a freight train. The tornado passed 150 yards from the house, causing significant damage to the neighborhood. Your basement remained intact, and you emerged to find the house destroyed.
Preparing for Tornadoes
To survive a tornado, you need a sturdy shelter. Your basement was designed to withstand EF5 winds, but even a basic shelter can save your life. Here’s how to build one:
Choose the Right Location
Your shelter should be underground, at least 12 feet below ground level. This depth provides protection from flying debris and the force of the wind. Ensure the shelter is accessible and located away from potential hazards like gas lines or septic tanks.
Use Strong Materials
Concrete walls and floors are ideal. They can withstand the pressure and impact of a tornado. Use rebar and steel reinforcement to strengthen the structure. The walls should be at least 18 inches thick, and the floor should be 12 inches thick. This ensures the shelter can withstand the force of the tornado.
Ensure Proper Ventilation
Install vents that can be closed during a tornado. They should be covered with metal grates to prevent debris from entering. Ensure there is enough ventilation to prevent carbon monoxide buildup from any fuel-burning appliances inside the shelter.
Add Emergency Supplies
Keep a survival kit inside your shelter. Include at least one gallon of water per person per day for at least three days, non-perishable food for three days, a first aid kit, flashlights, batteries, a NOAA weather radio, and a whistle to signal for help. Also, include a dust mask for each person to help filter contaminated air.
The Warning Signs
Tornadoes can be unpredictable, but there are signs to watch for. Here’s what to look out for:
Weather Patterns
Tornadoes often form in areas with warm, moist air and cold, dry air. Look for dark, greenish skies, large hail, and a rotating, funnel-shaped cloud. These are signs of severe weather that could lead to a tornado.
Sound
Tornadoes make a loud, roaring noise, similar to a freight train. If you hear this sound, it’s time to seek shelter immediately. The noise can be heard up to 10 miles away, giving you time to act.
Emergency Alerts
Stay tuned to local weather reports and sign up for emergency alerts. These can provide crucial information about approaching storms. Set up alerts on your phone and keep a battery-powered or hand-crank radio in your shelter.
After the Tornado
Emerging from your shelter after a tornado can be dangerous. Here’s what to do:
Check for Injuries
Assess yourself and others for injuries. Provide first aid if necessary. Do not move seriously injured people unless they are in immediate danger. Use a first aid kit to treat minor injuries and call for medical help if needed.
Inspect Your Home
Be cautious when entering damaged buildings. Wear sturdy shoes and gloves to protect yourself from sharp objects and debris. Check for structural damage before entering. Look for signs of instability like cracks in walls or floors.
Stay Informed
Listen to local news and emergency services for updates. They can provide information about safety measures and recovery efforts. Follow their instructions to ensure your safety and the safety of your community.
Document Damage
Take photos of the damage for insurance claims. This can help you receive the compensation you need to rebuild. Document everything, including the extent of damage to your home, belongings, and vehicles. Keep all receipts and records related to repairs and replacements.
Summary
Surviving a tornado requires preparation and quick action. A sturdy shelter, awareness of warning signs, and a plan for after the tornado can make all the difference. By following these steps, you can increase your chances of staying safe during a tornado.
