Tornado safety

1. Tornado Safety

Introduction

Tornadoes are violently rotating columns of air extending from a thunderstorm to the ground. They are among the most destructive forces in nature, capable of immense damage and posing a significant threat to life. Understanding tornado safety is crucial for everyone, especially those living in areas prone to these severe weather events. This article will provide a comprehensive guide to tornado safety, covering before, during, and after a tornado, as well as information on tornado watches and warnings, shelter options, and preparedness measures. This information is designed for beginners and aims to equip you with the knowledge to protect yourself and your loved ones. Understanding Weather forecasting is a key component of preparedness.

Understanding Tornado Formation & Terminology

Before diving into safety procedures, it's important to understand the basics of tornado formation and the terminology used. Tornadoes form within severe thunderstorms, specifically supercell thunderstorms. These storms have a rotating updraft called a mesocyclone. When this rotation tightens and extends towards the ground, a tornado may form. The intensity of a tornado is measured using the Enhanced Fujita (EF) Scale, which rates tornadoes from EF0 (weakest) to EF5 (strongest) based on the damage they cause.

Here's a breakdown of key terms:

• **Tornado Watch:** Issued when conditions are favorable for the development of tornadoes in an area. This means be prepared! Stay informed and monitor weather updates.
• **Tornado Warning:** Issued when a tornado has been sighted or indicated by weather radar. This means take action immediately! Seek shelter.
• **Mesocyclone:** A rotating updraft within a thunderstorm that can lead to tornado formation.
• **Supercell:** A thunderstorm with a rotating updraft (mesocyclone).
• **Wall Cloud:** A localized, persistent lowering of cloud base beneath a thunderstorm, often rotating. This is a visual clue that a tornado may be forming.
• **Funnel Cloud:** A visible condensation funnel extending from the base of a thunderstorm, but not yet touching the ground.
• **Debris Cloud:** A rotating cloud of debris near the ground, indicating a tornado is present, even if the funnel is not visible.

Understanding these terms, and regularly checking the National Weather Service website, will help you interpret weather information effectively.

Before a Tornado: Preparedness is Key

Preparation is the most critical step in ensuring your safety during a tornado. A proactive approach can significantly reduce the risk of injury or death. Here's a detailed checklist:

• **Develop a Tornado Safety Plan:** Discuss with your family where to go during a tornado and practice the plan. This should include identifying safe rooms and evacuation routes.
• **Identify a Safe Room:** The safest place to be during a tornado is an underground shelter, basement, or safe room. If none are available, an interior room on the lowest level of a sturdy building, away from windows, is the next best option. Avoid large rooms like gymnasiums or auditoriums. Building construction plays a vital role in the safety of a structure.
• **Assemble a Disaster Supply Kit:** This kit should include:

   * Water (one gallon per person per day for at least three days)
   * Non-perishable food (at least a three-day supply)
   * Battery-powered or hand-crank radio and NOAA Weather Radio with tone alert
   * Flashlight
   * First aid kit
   * Whistle to signal for help
   * Dust mask to help filter contaminated air
   * Plastic sheeting and duct tape to shelter-in-place
   * Moist towelettes, garbage bags and plastic ties for personal sanitation
   * Wrench or pliers to turn off utilities
   * Manual can opener for food
   * Local maps
   * Cell phone with chargers and a backup battery
   * Important documents (copies of insurance policies, identification, medical records)
   * Cash

• **Strengthen Your Home:** Consider reinforcing your home to make it more resistant to tornado damage. This can include anchoring the roof, bracing walls, and installing storm shutters.
• **Trim Trees and Shrubs:** Remove dead or weak branches that could fall and cause damage during a storm.
• **Stay Informed:** Monitor weather forecasts regularly, especially during severe weather seasons. Utilize multiple sources of information, including the National Weather Service, local news channels, and weather apps. Pay attention to Climate change and its potential impact on severe weather patterns.
• **Know Your Community’s Warning System:** Understand how your community alerts residents to tornado watches and warnings (sirens, radio, television, mobile alerts).

During a Tornado: Taking Immediate Action

When a tornado warning is issued, your immediate safety is the priority. Time is of the essence. Here's what to do:

• **If You Are in a House or Building:**

   * Go to the safe room or the lowest level of the building, in an interior room away from windows.
   * Crouch low to the floor, face down, and cover your head with your arms.
   * If possible, get under something sturdy like a heavy table or desk.
   * Stay away from doors and windows.  Flying debris is the primary cause of tornado-related injuries.
   *  Do not open windows. This is a common myth and does not reduce damage.

• **If You Are in a Vehicle:**

   * The safest option is to abandon the vehicle and seek shelter in a sturdy building.
   * If a sturdy building is not available, lie flat in a ditch or low-lying area, covering your head with your arms.  Be aware of potential flooding.
   * Do *not* try to outrun a tornado in a car or truck.  Tornadoes can change direction quickly and are often faster than vehicles.

• **If You Are Outdoors:**

   * Lie flat in a ditch or low-lying area, covering your head with your arms.
   * Be aware of potential flooding.
   * Stay away from trees, power lines, and other objects that could fall.

• **If You Are in a Mobile Home or Manufactured Home:**

   * Mobile homes are *not* safe during a tornado.  Evacuate immediately and seek shelter in a sturdy building or a designated community shelter.

• **If You Are at School, Work, or a Public Place:**

   * Follow the established emergency procedures.  Go to a designated shelter area.
   * Crouch low to the floor, face down, and cover your head with your arms.

• **Protect Your Head:** Regardless of your location, protecting your head is crucial. Use your arms, a pillow, a mattress, or any available object to shield yourself from flying debris.

Remember, the goal is to put as many walls as possible between you and the outside.

After a Tornado: Safety and Recovery

Once the tornado has passed, the danger isn't necessarily over. Here's what to do after a tornado:

• **Check for Injuries:** Provide first aid to anyone who is injured. Call for emergency medical assistance if needed.
• **Be Aware of Hazards:**

   * Downed power lines: Stay away from downed power lines.  Report them to the power company immediately.
   * Damaged buildings:  Avoid entering damaged buildings until they have been inspected by a qualified professional.
   * Debris:  Be careful of debris, which can be sharp and hazardous.
   * Gas leaks:  If you smell gas, evacuate the area immediately and call the gas company.
   * Water contamination:  Assume that the water supply is contaminated and drink only bottled or boiled water.

• **Report Damage:** Report damage to your insurance company and local authorities.
• **Document Damage:** Take photos and videos of the damage for insurance purposes.
• **Stay Informed:** Continue to monitor weather updates and follow instructions from local authorities.
• **Be Careful While Driving:** Roads may be blocked or damaged. Drive cautiously and be aware of hazards.
• **Help Your Neighbors:** Check on your neighbors and offer assistance if needed.
• **Beware of Scams:** Be wary of contractors who offer quick repairs at inflated prices.

Recovery from a tornado can be a long and challenging process. Seek support from family, friends, and community organizations. The Federal Emergency Management Agency (FEMA) provides assistance to disaster victims.
